[Wipe Away]

hello,

Can Someone Help ??

I specialise in builders cleans and am usually last on a job for clean then sparkle etc, I went to a nice big job this weekend 15 units, and this company gives me alot of work, got there this weekend and the window frames and windows were covered in concrete and i was only there to get the site ready for the mastic man, I took 2 days trying to get this s*** off and eventually managed to pressure wash most of the frames with my washers, its 4000psi but the water pressure was very low (borrowed from a neighbours garden then ran about 50 metres via hoses.....

Has anyone got any ideas how to get this stuff off ? I am struggleing, some advice would be great of ideas....

Are my washers powerfull enough ?, is there a chemical I can get, please HELP !!!!!!!

Brick acid,.. but wear goggles, gloves etc etc, its nasty stuff.
And make sure you NEVER get it on chrome or stainless steel.
