Hello everyone and thanks in advance for you help. I’m currently cleaning a deck that was stained last year with a dark red solid stain. I’m using the BEHR Quick-Fix Deck Finish Remover, but I haven’t been very successful. There are a lot of overhead boards left to clean and I’m having a very hard time with taking the stain off that part of the deck/porch. Am I just using the wrong remover? Please HELP!!!
