Last spring we FINALLY cleaned the siding at Steph's house. We used a pump-up sprayer for the cleaner we used. Part way through the cleaning, we discovered Ryobi had a battery powered chemical pump sprayer. We were very interested as the pump-up sprayer was proving to be a tedious, fatiguing option.
Fast forward to our recent trip to a DIY conference where we learned more about the Ryobi sprayer and ended up getting to bring it home with us! We immediately put it to the test with the moss, mold, mildew, and algae stain remover, Wet & Forget.
