What is the best box store bought solutions for each?
Hi James. Boy, I like EZ Cleaner by Amor. It comes in an attachable bottle, so you just put it on a hose. If you want to use natural products, baking soda and a stiff bristled broom works quite well. All that's required is elbow grease.
The best solution for this is to power wash them. You can buy a power washer, rent one or pay someone with a power washer to clean them.
I have a power washer, I wanted to know what the best liquor to use that I can buy at lowes or home depot to lit into power washer for decks and side wark?
