Outdoor decks are a wonderful place to chill, host meals al fresco, and soak up nature. Constantly exposed to the elements, however, decks can also get grimy and dirty pretty quickly. Keeping your deck clean is essential in both extending the deck's longevity and enjoying your time outdoors. Luckily, there are plenty of deck cleaners out there to suit your needs.

"Attentive maintenance can keep decks looking their best and make it less likely you’ll have to replace the whole thing prematurely," says Gina Perry, senior merchant of cleaning at Home Depot. Perry advises, "One of the keys to good deck maintenance is giving it regular inspections for rot and seeing whether it's structurally sound. Consider inspecting your deck in summer, as the air is warm and dry." To maintain a clean deck, you’ll want to use a deck cleaner.

To find the best deck cleaners we researched a variety of picks, keeping in mind the suggested surfaces, coverage area, and application method. We also consulted Perry for additional insight and spoke to a deck cleaning expert for her opinion and recommendations.

It works on fabric, concrete, wood, plastic, and vinyl, so you won't have to invest in multiple different cleaners.

You’ll need to mix the concentrate with water and spray it on your deck, so a spray bottle or tank sprayer is necessary.

If you’re hoping to use your cleaning time wisely and clean a whole host of outdoor items at once, this multifaceted cleaner is all you need. This fast-acting formula can remove mold, algae, or mildew from virtually any outdoor surface including metal, cloth, plastic, fiberglass, wood, composite, cement, asphalt, and more.

The smallest size bottle that this cleaner comes in is one gallon, but larger options are available. To use it, you’ll need to mix up a combination of half water and half cleaner. One gallon of the concentrate can clean 200-600 square feet, depending on the material and what you’re cleaning.

Because the concentration gets mixed with water and sprayed on a deck (or other items), you’ll need to purchase either a large-size spray bottle (best for small items) or the recommended tank sprayer, which is more efficient and easier for cleaning a deck. Both are sold separately, making for an additional cost.

Starting with a dry surface, spray the cleaner onto your deck, fully saturate it, and wait the appropriate time for your decking material. While the product gets to work ASAP, there's a range of times for how long you need to let it soak on a surface. For example, plastic only needs about three minutes while cement may require 15 minutes.

Since you always want to keep the surface wet while waiting, a second coating may be necessary for some decks. Once the recommended time frame has passed, simply rinse the surface clean with a garden hose and you’re all set.

The product is safe around lawns, plants, and landscaping, so don't worry if the runoff goes into your yard. Plus, you can also use it on fences, roofs, and patios, so you won't need to purchase any additional cleaners for those areas.

If you’re looking for a less expensive option, the best deck cleaner is this option from Olympic. The cleaner, which is best for wood surfaces, is ready to use so you won't have to mix any ingredients together.

Allow the product to stand for five to 10 minutes and then spray and rinse the deck with your water hose. If you are treating a vertical surface, like a fence or lattice, always start from top to bottom, so the wood catches any drips.

To successfully use this product, there are some precautions you should take. The brand recommends that any plants or vegetation that may come in contact with the cleaner be liberally sprayed with water before and after cleaning.

You don't allow this product to come into contact with plastic, vinyl, or fabric, so be sure to move any furniture or decorative items far away from where you're cleaning.

In addition, exterior mold can easily work its way into the house if left unchecked."

To use, you’ll want to dilute the vinegar concentration. Tougher jobs can handle full strength but if you want to tone it down, you can use up to 60 parts water. Once you’ve made your solution, use a handheld sprayer, sponge or mop, bucket, or pump-up sprayer.

Overall, the best deck cleaner is the 30 Seconds Outdoor Cleaner Concentrate because it's long-lasting and easy to use, though does require diluting and having a spray pump or spray bottle on hand.

An outdoor deck can be built in a variety of materials, like wood, concrete, or composite wood. To find the best deck cleaner for your home, consider the material and what each cleaner is suitable for. Otherwise, using the wrong cleaning agent on certain materials can cause long-term damage or discoloration.

The best deck cleaners are offered in a variety of formulations, like powder, liquid, or gel. Though one is not necessarily better than the other, some may have to be used with a pressure washer while others may need to be scrubbed or swept. When choosing the best deck cleaner formula, it's worth considering if you have the proper equipment, as well as how much effort you want to put in.

No matter the formula, it's also best to be cautious and wear protective clothing and eyewear as the cleaners may be heavily concentrated and can cause damage.

When it comes to choosing the best deck cleaner for your home, you’ll want to consider the size of your space. Some deck cleaners can cover a surface area that's a few hundred square feet while others can cover thousands. Most cleaners list the approximate size that their product will cover, but this can vary based on dilution ratios and the number of applications.

Some deck cleaners may require a pressure washer while others can just be sprayed onto your deck. When choosing the best deck cleaner, consider what equipment you have at home, as well as what suits your lifestyle best. For example, with some spray and liquid options, you may be able to set it and forget it. However, options that require equipment will take more of your time.

The best way to clean a deck without ruining it is to find the right cleaner for your specific needs. Each formulation is different and may require specific dilutions. Perry recommends homeowners, "read the instructions as some deck cleaners require a longer time to sit or may not require you to scrub the cleaner off."

This depends on the type of deck you have, the size, the preferred cleaning solution, and if you have a power washer. If you use a power washer, always follow the instructions for your type of material and start on the lowest setting. You can always increase the power.

If you don't own a power washer, consider a "tool rental service to get your project done. Use once, then bring it back–no maintenance required, and you won't need to store it either," advises Perry.

As an important first step, "Be sure to wear protective equipment to avoid contact with skin and eyes," says Perry. Then follow the instructions based on your deck's cleaner. For most formulations, the deck needs to remain wet for the solution to soak in, so be prepared to lightly mist your deck while the product is working. You can usually scrub any stubborn spots after the allotted time and rinse the whole deck with fresh water to complete the cleaning process.
