Easy way to remove flex adhesive from porcelain tiles?

[TheNibbler]

Had a bit of a disaster yesterday...

My bathroom guy accidently used my wall tiles to tile the floor. We managed to get the tiles up intact but the back of the tiles are caked in fast setting white flex adhesive.

I need to salvage these tiles as without them I'm not sure I have enough to finish the job on the walls. I'm reluctant to buy more as they're pretty big 60x30cm and cost £55 a box.

I've managed to clean up 4 with a hammer and chisel but its bloody hard work and took ages.

Does anyone know an easier way or some chemical I could use to remove the dried adhesive?

Many thanks!

Try a spot of methylated spirit, it often works on grout and adhesive.

Thanks!

Do you have to dilute it and/or leave it to soak in?

Just soak a rag straight from the bottle and rub it you may need to leave it on for a few minutes if after say five or ten it has not softened chances are it isn't going to work
