Kenny55 43 Report post Posted October 26, 2017 Had a similar issue in the past so far the only thing that managed to work for me was something called HCL89. It had managed to clean my tiles and restore them to their original self One good thing i like about it is that creates a protection layer that helps prevent my tiles from getting too overly dirty I usually get it from http://hcl89.byethost10.com or http://hcl89.atwebpages.com Hope this helps you out 2 Share this post Link to post Share on other sites

DillonM12 0 Report post Posted March 27, 2020 Try bleach again, and if it doesn't work, try acetone. It's really concentrated. Share this post Link to post Share on other sites
