  Don't know if anyone can help but if so could be a big money spinner. Do you
  find marks of small rough circles on your customer windows and you can't get
   them off. Have tried but customers are now taliking about getting new windows.

   I spoke to a builder about this and apparently it is the glue that adheres
   the stones to the walls, when it rains it runs down the windows. Hence
   the marks on the windows.

   Any substance you know of take this off.

   Cheers

 Cheers I have a bottle of that and read the instructions, what type of scrub do
  you use. And is it potent as it says, do you have to wear protective clothing !
