I have a patio that hasn't been maintained. The bricks on one side are
discolered with a moss/midldew.
Previous posts say bleach or muric acid? Are these still the best
solutions? Anything better out now adays?
Use bleach first, a garden sprayer makes it easy, bleach will kill mold
acid wont. If you want it cleaner a mild scrubing or powerwasher will
do. If you still want it cleaner then muriatic acid and a powerwash.
after it is clean regular spraying with bleach will keep off the mold.
