Can You Use Wet and Forget to Clean Your Deck? A Comprehensive Guide
Yes, you can use Wet and Forget to clean your deck, and it’s often a highly effective solution for removing moss, algae, mildew, and lichen. However, understanding the product, its application, and potential impacts on your specific deck material is crucial for achieving the best results and avoiding damage.
Understanding Wet and Forget for Deck Cleaning
Wet and Forget is a popular non-bleach cleaner designed to eliminate unwanted organic growth over time. Unlike some deck cleaners that require vigorous scrubbing or power washing, Wet and Forget is a leave-on formula that allows natural elements like rain and wind to gradually wash away the contaminants. The active ingredient in Wet and Forget is typically alkyl dimethyl benzyl ammonium chloride (ADBAC), a quaternary ammonium compound (quat) known for its antimicrobial and algaecidal properties.
This product’s appeal lies in its ease of use and long-lasting effects. You simply apply it, saturate the affected areas, and then let nature do the rest. Over time, the moss, algae, or lichen will turn brown or black and eventually disappear. This process can take weeks or even months, depending on the severity of the growth and the weather conditions.
Suitability for Different Deck Materials
While Wet and Forget is generally safe for a variety of deck materials, it’s essential to consider your deck’s specific composition:
Wood Decks
Wet and Forget is often a great choice for wood decks, including pressure-treated lumber, cedar, and redwood. However, always test a small, inconspicuous area first to ensure the product doesn’t stain or discolor the wood. Certain wood types might react differently to the cleaner. Older, weathered wood decks might benefit from a more concentrated application.
Composite Decks
Composite decking is generally more resistant to the chemicals in Wet and Forget than natural wood. Most manufacturers approve the use of non-bleach cleaners like Wet and Forget on their products. However, consult your composite deck manufacturer’s guidelines before applying any cleaner. Improper cleaning can sometimes void the warranty.
Painted or Stained Decks
If your deck is painted or stained, exercise extra caution. Wet and Forget might fade or discolor the finish. A test spot is absolutely necessary. If you notice any adverse effects, avoid using Wet and Forget on the entire deck. Consider using a deck cleaner specifically formulated for painted or stained surfaces.
Application Techniques for Optimal Results
Applying Wet and Forget correctly is crucial for achieving optimal results:
Preparing Your Deck
Before applying Wet and Forget, remove any loose debris such as leaves, twigs, and dirt. This will allow the cleaner to penetrate directly into the moss, algae, or lichen. You can use a broom, leaf blower, or garden hose to clear the deck.
Mixing and Application
The standard Wet and Forget concentrate needs to be diluted with water. The recommended dilution ratio varies depending on the product formulation and the severity of the growth. Always follow the instructions on the product label. Use a garden sprayer to evenly apply the solution to the affected areas.
Best Time to Apply
Choose a day with no rain in the forecast for at least 4-6 hours. This allows the Wet and Forget to dry on the surface and effectively kill the growth. Apply in the early morning or late evening to avoid the solution drying too quickly in direct sunlight. Avoid applying when temperatures are below freezing.
Potential Risks and Precautions
While Wet and Forget is generally safe, it’s essential to take precautions:
Safety Gear
Always wear gloves, eye protection, and long sleeves when applying Wet and Forget. Avoid contact with skin and eyes. If contact occurs, rinse thoroughly with water.
Environmental Considerations
Avoid spraying Wet and Forget directly into bodies of water or storm drains. The product can be harmful to aquatic life. Be mindful of runoff, especially if you have plants or vegetation nearby. Consider using a more environmentally friendly alternative if this is a significant concern.
Potential for Slippery Surfaces
After application, Wet and Forget can leave the deck surface slightly slippery, especially when wet. Be cautious when walking on the deck until it has completely dried. Consider applying a non-slip coating to the deck after cleaning.
Frequently Asked Questions (FAQs) about Using Wet and Forget on Decks
Here are some frequently asked questions about using Wet and Forget on your deck, offering practical advice and helpful tips:
1. How long does it take for Wet and Forget to work on a deck?
The time it takes for Wet and Forget to completely eliminate moss, algae, or lichen on a deck can vary significantly. It often takes several weeks or even months to see complete results. The timeframe depends on the severity of the growth, weather conditions, and the type of organism being targeted. Regular monitoring and a second application in particularly stubborn areas may be necessary.
2. Can I use Wet and Forget on a newly built deck?
It’s generally safe to use Wet and Forget on a newly built deck, but allow the wood to weather for a few weeks before application. This allows any treatments applied during the manufacturing process to dissipate. Always test a small, inconspicuous area first to ensure there are no adverse reactions.
3. Does Wet and Forget kill grass and plants?
Yes, Wet and Forget can harm grass and plants if directly sprayed on them. Avoid spraying the product near vegetation. If accidental contact occurs, immediately rinse the affected plants with water. Consider covering nearby plants with a tarp during application.
4. What is the best dilution ratio for Wet and Forget when cleaning a deck?
The recommended dilution ratio varies depending on the specific Wet and Forget product. Always consult the product label for the manufacturer’s instructions. Typically, it’s a 5:1 or 7:1 ratio of water to Wet and Forget concentrate. For severe infestations, a stronger concentration might be needed, but testing is still recommended.
5. Can I power wash my deck after applying Wet and Forget?
While you can power wash your deck after the Wet and Forget has had time to work (several weeks or months), it somewhat defeats the purpose. Wet and Forget’s advantage is its “leave-on” approach. Power washing will remove the protective layer and may require you to reapply the Wet and Forget. If you choose to power wash, do so gently to avoid damaging the deck.
6. Will Wet and Forget damage the sealant on my deck?
Wet and Forget is unlikely to damage most deck sealants. However, it’s always a good idea to test a small area first to ensure compatibility. If you notice any discoloration or degradation of the sealant, avoid using Wet and Forget on the entire deck. Re-sealing your deck periodically is generally recommended, regardless of which cleaner you use.
7. Is Wet and Forget safe for pets and children?
While Wet and Forget is safer than many bleach-based cleaners, it’s still important to keep pets and children off the deck until it’s completely dry. Once dry, the product is generally considered safe. However, avoid allowing pets to lick or ingest the solution.
8. Can I use Wet and Forget on my deck railing?
Yes, you can use Wet and Forget on your deck railing, provided the railing is made of a compatible material like wood or composite. Follow the same precautions and application techniques as you would for the deck surface. Test a small area first, especially if the railing is painted or stained.
9. How often should I apply Wet and Forget to my deck?
The frequency of application depends on the local climate, the amount of shade the deck receives, and the type of growth you are trying to control. Typically, reapplication is needed every 6-12 months. Monitor the deck for signs of regrowth and reapply as needed.
10. Can I use Wet and Forget Mold and Mildew on my deck?
Yes, Wet and Forget Mold and Mildew is generally safe to use on decks, as it contains the same active ingredient (ADBAC) as the original formula. Ensure you follow the dilution instructions on the product label, and always test a small, inconspicuous area before applying to the entire deck.
11. What are some alternatives to Wet and Forget for deck cleaning?
Alternatives to Wet and Forget include oxygen bleach cleaners, deck washes specifically formulated for your deck material, and DIY solutions like a mixture of water and vinegar (for mild cleaning). Always research the potential effects of any cleaning product before applying it to your deck.
12. Where can I buy Wet and Forget?
Wet and Forget is widely available at home improvement stores, hardware stores, and online retailers like Amazon and Walmart. Compare prices and read customer reviews before making a purchase.
