i have a new 2nd hand tank. it is very smeary in places. how do i get rid of this? ive tried white vinegar. it cleared alot of the lime scale but not the white smear on glass. when i dampen a cloth and wipe it, it looks as if its gone, but when it dries it back again.
is it possible to get rid of these marks??
