What are the advantages of a homemade deck cleaner?

Two advantages of using a homemade deck cleaner are that it could save a homeowner money and that it might have fewer harmful environmental effects. One drawback of using a homemade deck cleaner is that it might take more work than a power washer.

One type of cleaner that can be used is oxygen bleach, which is often available in powder form. A combination of water, bleach and dishwashing detergent is also effective for annual cleanings. A mixture using trisodium phosphate is an option for decks with algae problems, while adding rubbing alcohol and Murphy's oil soap to a mixture can be useful in battling mildew.
