It’s supposed to be environmentally friendly and clean black streaks without scrubbing…on decals too, without hurting them. You know how filthy the Lurch is…I gotta try something goooood! :unsure: May 28, 2014 at 4:30 am #3702 Julie GramollParticipant HI Norma, I bought some Bio-Kleen last season and used on the recommendation of a friend. I like it. It does take the black streaks off. I also used it on the underside of my awning. I also bought the sudsy cleaner as well. May 28, 2014 at 5:16 am #3703 NormaParticipant Thanks, Julie. Think I’ll get them both, too! Author Posts Viewing 3 posts - 1 through 3 (of 3 total) You must be logged in to reply to this topic. Log In Username: Password: Keep me signed in Log In
