CLASSICPW 14 Report post Posted April 26, 2005 I've had 2 jobs this year to remove dark grey runs coming off windows on brick. I've tried everything except muriatic acid, any ideas? Share this post Link to post Share on other sites

0 Howard 50 Report post Posted April 26, 2005 I used a product from ecochem called "Safe Restore" used it on the commercial building I cleaned (pictures in Gallery) it works on all sorts of stains, rust, green stains from brass/copper plates on memorials. I'd give it a try, I know it works for me. Share this post Link to post Share on other sites
