i am repalcing the bath, etc in my batheroom, and am trying to save and reuse wall tiles, these have come off easily around the bath. Is there a solvent or similar that will soften the old tile adhesive to allow it to be scraped off. The tiles are old and i'm sure replacements will not be available. I'm sure that i could get frustrated trying toscrape/chip old adhesive off and break some. Any suggestions would be appreciated
