Wet and Forget Patio Cleaner Where to Buy and What to Get
What Wet & Forget actually is (and what it's genuinely good at)

Wet & Forget Outdoor is a no-scrub, no-rinse cleaner designed specifically to kill and remove moss, mold, mildew, and algae stains from outdoor surfaces. The way it works is different from most patio cleaners: you spray it on and then leave it. Wind and rain do the work over the following weeks, gradually breaking down the growth until it disappears. There's no pressure washing, no scrubbing, and no bleach. It's genuinely a set-it-and-forget-it approach.
Where it really shines is on surfaces that are tricky to treat aggressively, like sandstone, slate, and natural stone pavers, where bleach-based products can discolour the surface and pressure washing can erode the material. It's also very useful for large areas like driveways, walkways, and patios where scrubbing is just not realistic. That said, it's not an instant cleaner. If you need the patio looking spotless this weekend for a party, this isn't the product. It works over weeks, not hours.
It's worth knowing that the product was recently rebranded from Wet & Forget Outdoor to Wet & Forget Outdoor MAX. The formula hasn't changed at all, just the label. So if you see either name on the shelf, you're looking at the same original product.
Where to buy Wet & Forget in 2026
Here are all the reliable places to pick it up, whether you want it today or are happy to order online.
The official brand website
Buying from wetandforget.com means you'll always get the current product version, and it's a good option if you want to order refills or the hose-end format directly. Pricing is fairly standard, and the site occasionally runs bundle deals. Shipping times vary, so if you're in a hurry, a physical retailer is faster.
Home Depot

Home Depot is probably the most reliable physical retailer for Wet & Forget. They carry the 0.5 gallon concentrate (model 800064), including a case-of-4 option if you're covering a large area or want to stock up. They also carry the Xtreme Reach hose-end refill (48 oz, model 805048RF), which is useful once you already own the hose-end nozzle attachment. Check the Home Depot website or app to confirm your local store has it in stock before making the trip.
Lowe's
Lowe's stocks the 1 gallon concentrate (model 800066CA), which is a great size for patios and driveways. The 1-gallon version gives you more coverage per dollar if you're treating a reasonably large outdoor area. Same advice applies: check the app or website for local availability before driving over.
Ace Hardware
Ace Hardware carries the 0.5 gallon concentrate (Mfr # 800064) online and through many of their independently owned stores. Ace is worth checking if you're in a smaller town where big-box stores aren't as close. Stock levels at Ace vary more than at the national chains, so calling ahead is a smart move.
Walmart

Walmart carries the Xtreme Reach hose-end format in a 48 oz bottle, both online and in many stores. If you want the ready-to-spray hose-end version and you have a Walmart nearby, this is a quick option. In-store availability is less consistent than Home Depot or Lowe's for Wet & Forget specifically, so checking the Walmart app for your local store's stock before going is a good idea.
Costco
Costco carries the Xtreme Reach Hose End in a 68 oz bottle, which is the largest single-bottle size I've seen in retail. This is available through Costco's same-day delivery service and may also be on the warehouse floor depending on your location and season. If you're already a Costco member and treating a big area, this is good value.
Amazon
Amazon is a solid fallback if you can't find the right size or format locally. You'll find multiple Wet & Forget variants there, including concentrate and hose-end options. Just double-check you're buying from the official Wet & Forget store or a reputable seller to avoid old stock or counterfeit listings.
Use the brand's store finder
The quickest way to find Wet & Forget near you is to use the official store finder at wetandforget.com. Enter your zip code and it shows you nearby retailers that carry the product. This saves the frustration of driving to a store only to find an empty shelf, especially because smaller hardware stores and garden centres sometimes carry it seasonally.
Which Wet & Forget product to buy for your patio

There are three main formats. Picking the right one matters more than most people realise, so here's a quick breakdown based on your setup.
| Format | Best For | Where to Find It | Notes |
|---|---|---|---|
| Concentrate (0.5 gal or 1 gal) | Large patios, driveways, walkways, regular maintenance | Home Depot, Lowe's, Ace Hardware | Mix with water (5:1 ratio), apply with a pump sprayer. Most cost-effective for big areas. |
| Xtreme Reach Hose End | Medium to large patios, fences, decks, hard-to-reach areas | Walmart, Costco, wetandforget.com | Attaches to your garden hose. No mixing needed. The nozzle has significant reach, good for roofs and high fences too. |
| Ready-To-Use (RTU) | Small patios, spot treatments, furniture, tight spaces | wetandforget.com, some hardware stores | Pre-mixed, just spray and leave. Easier for beginners but more expensive per square foot. |
Matching the product to your surface and problem
Wet & Forget Outdoor MAX works across all the common patio surfaces: concrete, brick, pavers, natural stone (slate, sandstone, limestone), and porcelain. It's especially well-suited to natural stone like sandstone and slate where you need a gentle approach. The formula is free from bleach and phosphates, so it won't strip colour from sensitive stone or leave residue in the joints between pavers.
- Green algae, moss, or black mold on concrete or pavers: concentrate or hose-end works well, applied in spring or autumn before the growing season peaks.
- Lichen or stubborn moss on natural stone (slate, sandstone): the concentrate applied at full dilution and left for several weeks is the right approach. Don't expect overnight results.
- Mildew staining on porcelain tiles: the RTU or concentrate both work here. Porcelain is less porous, so results tend to come through faster.
- General green growth on large driveways or patios: the 1-gallon concentrate from Lowe's is the best value for this job.
- Rust, grease, or pet stains: this is where Wet & Forget is not the right tool. It targets biological growth only. For rust, you need an oxalic acid-based cleaner. For grease, a degreaser or alkaline cleaner is more appropriate.
Buying tips: sizes, refills, pricing, and what to watch for
The 0.5 gallon concentrate (800064) at Home Depot and Ace typically covers around 1,800 to 2,000 square feet when mixed at the standard 5:1 dilution, which is usually plenty for an average patio plus a path or two. The 1-gallon version at Lowe's doubles that coverage and generally works out cheaper per square foot. If you're treating a large area or want to do the whole back garden, the case-of-4 from Home Depot is worth considering.
For the hose-end format, the 68 oz Costco version is the best single-bottle value, but only if you have a Costco membership. The 48 oz Walmart version is easier to find and good for most standard patio jobs. Once you own the Xtreme Reach nozzle/applicator, buy the refills (48 oz, 805048RF at Home Depot) rather than replacing the whole bottle each time. It's cheaper and less plastic waste.
One important heads-up: there was a CPSC recall in 2024 affecting certain 48 oz and 68 oz Xtreme Reach hose-end bottles due to nozzle issues. If you're buying from a physical store, check that the product has a current manufacture date and hasn't been sitting on the shelf since before the recall. The brand's website and major retailers should only be selling compliant stock at this point, but it's worth being aware of when buying from smaller shops or marketplace sellers.
Shipping on concentrate bottles can be slower or more expensive from some retailers due to the liquid weight. If you're ordering online and need it quickly, check whether your nearest Home Depot or Lowe's offers same-day or next-day ship-to-store before defaulting to a slow delivery option. For large orders (case of 4), shipping from Home Depot online is often free or low cost.
How to use Wet & Forget safely and get actual results

The most common mistake I see is people applying it wrong and then assuming it doesn't work. Once you know the right process, this also becomes your go-to guide for <a data-article-id="CC690481-1093-4440-867E-38797FF17083">how to use Wet & Forget patio cleaner</a> correctly from start to finish. It works, but you have to follow the process. Here's how to do it properly.
- Apply to a dry surface. This is the most important step. If the patio is wet or rain is forecast within a few hours, wait. The product needs to dry onto the surface to start working. Early morning application on a dry day is ideal.
- For concentrate: mix 1 part Wet & Forget to 5 parts water in a pump garden sprayer. Apply liberally until the surface is thoroughly saturated but not pooling.
- For hose-end (Xtreme Reach): connect to your garden hose, set the dial to the correct setting, and spray across the surface. No mixing needed.
- For RTU: just spray directly from the bottle. Useful for furniture, railings, and small areas.
- Protect nearby plants by rinsing them with water before you start and again immediately after application. The product isn't designed to harm plants but rinsing is good practice, especially on windy days.
- Leave it. Don't rinse it off. Rain and wind do the work. You'll usually start seeing results in 1 to 3 months depending on the severity of the growth and your local weather. Heavy moss or lichen can take longer.
- Reapply once a year for maintenance once the surface is clean. This is much easier than treating heavy buildup.
Pets and children can use the area once the product has dried, which is typically a few hours after application. Don't let them onto the patio while it's still wet from spraying. The product contains no bleach, which is one reason it's popular for households with pets and gardens with sensitive planting nearby.

What to do if you can't find Wet & Forget near you
If the shelves are bare and you need something sooner, there are a few genuinely good alternatives depending on your surface and problem.
Similar spray-and-leave cleaners
Patio Magic is the most widely known UK equivalent (though less relevant if you're in the US), and in the US market, products like Spray & Forget and 30 Seconds Outdoor Cleaner work on the same principle: apply, leave, let rain finish the job. These are worth considering if you're after the same no-scrub experience. If you're looking at broader spray-and-leave options, the reviews of similar products in that category are a useful reference point.
Faster-acting alternatives for urgent cleaning
If you need the patio clean quickly and can't wait for a no-rinse product to do its thing over weeks, here are your options by surface type:
- Concrete and brick pavers: a diluted bleach solution (sodium hypochlorite) or an oxygen bleach product like Sodium Percarbonate works well and gives faster results. Pressure wash after 20 to 30 minutes.
- Natural stone (sandstone, slate, limestone): avoid bleach entirely. Use an oxygen-based or enzyme cleaner specifically labelled safe for natural stone. Apply, leave for 15 to 30 minutes, then rinse with low pressure.
- Porcelain patio tiles: most cleaners are safe here. A patio cleaner concentrate or diluted bleach solution works quickly. Rinse thoroughly afterwards.
- Stubborn moss or lichen on any surface: iron sulphate-based products (often sold as lawn moss killers) can also be used on hard surfaces for heavy moss treatment, though rinse-off is essential and staining is possible on light-coloured stone.
The honest truth is that no same-day patio cleaner will do what Wet & Forget does without some physical effort involved. If you want truly no-effort cleaning, Wet & Forget (or a comparable spray-and-leave product) is the category to buy in. If you're trying to treat outdoor fabric or shade items, you may also want to ask can you use wet and forget on patio umbrellas to see whether the spray-and-leave approach carries over safely. If you're wondering, do you have to wash off patio magic, the key is that it is also designed to be left to work rather than scrubbed away immediately Wet & Forget (or a comparable spray-and-leave product). If you are comparing options, it helps to look at Wet and Forget versus Patio Magic to see which spray-and-leave product fits your patio and your timeline. But if speed matters more right now than effort, a traditional cleaner plus a stiff brush or pressure washer will always get you there faster. Once the patio is clean, coming back to Wet & Forget for annual maintenance is a smart way to keep it that way with minimal work going forward. If you're still deciding, reading wet and forget patio cleaner reviews can help you gauge real-world results for your specific patio surface.
FAQ
If I see Wet & Forget Outdoor versus Outdoor MAX, are they different products?
It comes up as Wet & Forget Outdoor or Wet & Forget Outdoor MAX after the rebrand, and they refer to the same formula. However, availability varies by store and season, so if you only see one label, you can still buy it as long as it matches the Outdoor (MAX) product line you are trying to treat patios with.
Should I buy concentrate or the Xtreme Reach hose-end format?
For the hose-end bottle, the key is to buy refills once you already own the Xtreme Reach applicator. The 48 oz refill format is typically cheaper per use and reduces waste, while concentrate is usually the better deal if you are diluting for large coverage and can store it safely.
What should I check to make sure I am not buying recalled Xtreme Reach bottles?
If you are shopping in-store, the safest way to avoid old stock is to check the manufacture date on the label or box and look for a current date after the 2024 CPSC nozzle recall. If you are buying from a marketplace listing (not a major retailer), confirm the seller is the official Wet & Forget store or a verified retailer and that the listing is not showing unusually discounted, dated inventory.
Will Wet & Forget start working right away, or does it always take weeks?
Yes, but the timeline depends on growth type and weather. Plan on multiple applications spaced out if needed (for example, for heavy algae), and give it time for rain and wind to work, usually weeks rather than hours. If you need immediate results, plan a different approach because spray-and-leave cleaners are not designed to look perfect the same day.
How do I get the best results on natural stone or porous pavers without damaging them?
If you are trying to avoid residue or color issues on sensitive materials, choose Outdoor MAX and skip bleach or harsh cleaners before or after. You generally do not need to pressure wash to get results, but if you have loose dirt or moss mats that are deeply embedded, you may need light brushing first so the chemical can contact the surface evenly.
What is the most common way people apply it wrong, and how can I avoid wasting product?
Concentrate requires dilution, and the common issue is using the wrong mix strength or skipping coverage. Measure the dilution (often the standard 5:1 process), mix thoroughly, apply enough product for full wet coverage, then do not rinse it off, since rinsing too soon can reduce effectiveness.
What should I do if my spray looks patchy or doesn’t seem to cover evenly?
If you have a nozzle or sprayer that clogs or delivers uneven spray, the application will look patchy and may seem like it is not working. For concentrate, use an appropriate sprayer that produces a consistent fine spray, and if you are using the hose-end system, ensure the applicator is properly seated and not spraying inconsistently before you treat the whole area.
When is it actually worth buying refills instead of new bottles?
Refill purchasing only makes sense if you already have the Xtreme Reach hose-end applicator. If you do not, buying a starter bottle is usually the most cost-effective path, then switching to refills is better for future treatments. If you are treating many areas repeatedly, calculate whether concentrate plus dilution is still cheaper per square foot for your specific patio size.
When can pets and kids go back on the patio after spraying?
The product is typically safe for people and pets once it has dried, but you should keep children and animals off the treated surface while it is still wet from application. Also, avoid letting runoff pool in small enclosed areas (like near containers) right after spraying, since local puddling can extend drying time.
What is the best option if my local stores say they are out of stock?
If Home Depot or Lowe’s shows none of the specific model/size near you, the store finder on the brand site is still the best first check because it reflects nearby retailer stock. If nothing nearby has it, ordering from the official Wet & Forget site reduces the risk of old inventory compared with third-party marketplace sellers.
