What is the best way to get gypsie moth p**p stains off a new deck?

Question

The deck was just a few weeks old when the gypsie moth caterpillars came and did their thing all over. The p**p was swept off 2-3 times a day, but still some stains remain. Because the deck is new there was no stain or sealer on the deck prior to the pooping. (Already tried a pressure washer and it didn't work)

Answer 1

Since you didn't seal it you might need to use a light grain sand paper on it.   This would possibly cause you to have to restain it or touch it up.   then DEFINITELY seal it.  Also, you might try mold and mildew spray remover on it and use an abrasive spong  as long as it doesn't contain a bleach.
