Post by: AC Pressure on June 10, 2010, 05:44:46 pm

Hello guys i cleaned a drive recently and part of it was covered in white marks which still remain after cleaning any idea what may be causing this and how to remove it.

Looks like clay pot plants etc. have been there. These can leave a permanent stain.

Would have to be very big clay pots this covers an area of 3 by 2 mtrs  :)
