Hi, I just got thinking that my ornaments look terrible. They're dark green and I can't get the algae for anything!! I scrubbed and scrubbed and it barely came off. I don't want to bleach them because I just don't. And also, I dont want to sit and scrub scrub scrub for 2 hours to get a little lighter green. Sooo, what other way is there to get it off easier? Thanks!
