Shane 14 Report post Posted March 19, 2007 Hello all, its been awhile. How would you clean/remove this white stuff (phosphorous I think, not sure) from brick. We tried 4000psi w/heat, nothing. Any suggestions would be greatly appreciated, thanks Shane. Share this post Link to post Share on other sites

0 PressurePros 249 Report post Posted March 19, 2007 I can guarantee you you made the problem worse with heat and 4000 psi. You need acid. There are scecialty chemicals made by EacoChem and Aldon that will work. Share this post Link to post Share on other sites
