Depending on what you have on your deck, you need to find a good cleaner for your specific needs. We clean wood with few different types of cleaners. Good questions to ask before start cleaning are: What type of wood do I have? What type of stain currently have on the deck? Am I going to strip, or wash the wood? What I’m trying to clean (dirt, derbies, mold, algae)? If you know answers cleaning the deck will be fun. Just watch for correct concentration and neutralization schedule if applicable.
