Got rid of the old tiles in the kitchen.

Some of them were on plasterboard, and I have some holes to mend, but I
can cope with that. The problem is that some of the old tile adhesive is
still adhering to the PB. What's the best way of getting a clean
surface, ready for retiling, without destroying the PB?


There isn't one! Rip out the plasterboard and replace it - it's dirt
cheap. You don't have to skim the new board before tiling it.
