Scrub brushes screwed to your steps are perfect for cleaning shoes and boots to keep from tracking dirt in the house.
Scrub brushes with a plastic body won’t rot and last longer than wooden brushes.
Start by drilling two 3/16” holes in each scrub brush.
Attach the scrub brushes to the bottom step with 1 5/8” coated decking screws.
Hose out the scraper periodically to remove dirt, and unscrew it when refinishing the steps.
