Tell us about yourself!
This was fantastically helpful advice! We just realized that trick-or-treaters were likely to wipe out on the algae-ridden landing of our front steps. After reading your instructable I grabbed a scrub brush and a bottle of hydrogen peroxide, and five minutes later, our landing is safe for ghouls, witches and any other variety of Halloween visitor! Thank you!
