Best Deck Cleaner to Keep Your Deck Spotless

You love spending time out on your deck, but it can fade and look worn out with sunlight exposure and heavy traffic. Even if you make a point to routinely maintain it, you’ll need a high-quality deck cleaner on hand and ready to use to bring the rich hues out in the wood and make it look like new again. A deck cleaner can safely get rid of layers of grime without stripping the deck paint or wood of oils or making it look dull and faded, and there are several excellent brands to choose from when you start shopping.

Deck Cleaner Buyer’s Guide 

If you need a deck cleaner, you most likely want to prep your deck to stain or refinish it or clean it to get rid of any stains or set-in debris. If you want it to clean, it’ll remove any dirt, grime, mold, or mildew while leaving the deck with the stain and varnish intact. If you want to prep it, you’d apply it before you apply sealer, varnish, or stain to give yourself a clean work surface. 

You can apply it by hand with a scrub brush or a pressure washer. This will help the deck cleaner remove unwanted blemishes and dirt from your deck’s surface. It can effectively cut through fine moss, lichen, algae, weathered stain, oxidation patches, dirt, oil, grease, and grime. Once you clean it, you can sand it to remove any remaining patches of stain. 

Deck 2 Guide
A well-maintained deck will look nice, resist stains, and have a protective barrier to prevent weather damage. Using a high-quality cleaner is one way to extend the life of your deck and make it look presentable all year round. 


If you were to use your deck cleaner before you refinish your hardwood floor or deck, the concentration would be very important. This is a measure of how potent the product is, and it can range from a very diluted formula to a very concentrated one. Usually, when you buy a concentrated formula, you’ll use the instructions to dilute it down before you use it to make it last longer. If you don’t, it could strip the wood down much further than you originally wanted it to. 


A lot of deck cleaners made the switch to using biodegradable formulas without any harsh chemicals that could harm the surrounding environment. Since you will usually wash the cleaner off your deck or patio and onto your lawn or flowers, you want something that won’t burn them. This is especially important if you plant to clean your deck on a regular basis. Double-check that the formula is environmentally-friendly, biodegradable, and that it won’t cause issues for your plants or lawn. It’ll usually say right on the package whether or not it is. 


The most popular type of deck cleaner comes in liquid form, but you can also get granular form. With the liquid form, you either pour it straight onto your deck, put it in a pressure washer and spray your deck, or dilute down the concentrate before applying it. Granular or powder form requires you to sprinkle it on the deck and apply a layer of water so it foams and starts to lift the stains. Both work, but the liquid usually has a much stronger formula to help it lift stains

Deck 3 End
Decks develop stains over time, and the varnish can peel away. It’s important that you remove any grime before you refinish your deck to give yourself a clean work surface for the stain to stick too. 


Oxygenated bleach has really grown in popularity over the past several years because it can tackle a broad range of stains without being too harsh on your skin or eyes. These cleaners contain Sodium Percarbonate, and this makes it slightly more environmentally friendly than traditional bleach. Check and see which ingredient your product uses before you apply it to your deck. This will give you a good idea whether or not it’ll damage the surrounding area. 

Square Footage

How large is your deck? You’ll have to find the square footage to make sure you’re buying enough product to cover it. Some deck cleaners can effectively clean up to 2,500 square feet, and other cleaners may only go as far as 750 square feet. You may want to buy enough so you have enough product to cover your deck twice to get it very clean. 

Bottom Line 

Deck cleaners can effectively lift a lot of stubborn stains and ground-in grime and dirt from your deck to make it look new again. I’ve rounded up several quality options that are both environmentally-friendly and not, and the short buyer’s guide can help you narrow down your choices to find the product that suits your needs the best.
