We got some heavy rain this morning so I took the time to scrape off my deck and put some fresh blades on. I knew the grass was going to be wet so I decided to try PAM spray on the bottom of the deck. Ive heard some good things about it and thought I would give it a shot. It worked great! The bottom of my deck stayed clean and there was less clumping with the wet grass. If anyone hasnt tried it yet I HIGHLY reccomend it.
