adhesive removal

Stick it back up?

WD40 is worth a try.

Can't stick it back on without removing the old adhesive. If I put more stuff on top it won't fit against the wall IYSWIM. I'll get some WD40 tomorrow and try it.

Are you sure boiling water would crack the tile? I am happy to be corrected but I would have thought tiles were meant to withstand boiling water. Perhaps use soapy water.

I hope you manage to remove the adhesive.

Would steam soften and loosen the adhesive? Do You have a steam cleaner you can try. I use mine to clean the bathroom tiles without damaging them.
Or a wallpaper stripper steam pad held there.

I have something similar to this for just that sort of problem:

Meant to add a disclaimer - I've never used it on tiles.

I think Wilko has similar products (if you have one near you).

White spirit might work

Nail polish remover?

Kathsue - I’ve just asked my very practical DH and he says try very carefully to slide/cut behind the glue just a little at the top and then dribble a little WD40 in. Give it time to work and repeat....he says it will work but takes time. Good luck!

Try Multi-Solve. DH used it to remove the sticky labels that are stuck to the floor when cleaning in Waitrose. You can use it on glass, so I reckon it would be safe to use on tiles.

Oh, I meant to say that the floor is highly polished tiles, and Multi-Solve doesn't leave marks.

Try sliding some dental floss behind the blob of glue and cutting into it with a sawing motion then try the wd40 or sticky stuff remover but read the instructions . Apply then leave for 10 whole minutes or it does not work.
If all else fails ... A hammer ?and chisel.

Multi-Solve first and then WD40 if that doesn’t work.

I'd try a window scraper paint remover but then I'm pretty clumsy and the dental floss would probably be a better idea. Once it's off you can now get suction toilet roll holders which work well on tiles - we've had one on our toilet wall for over a year now and it's never come off. Tiles need to be perfectly flat though so if they're the patterned type it won't work.

Sticky stuff remover, available from Lakeland. I use it to remove everythi g from price tags to tar marks on floors. It has never let me down, even takes chewing gum out of hair.

Suggest you do not use WD40 as it will leave residue on the tiles and nothing will stick again.

Maybe warm it with a hairdryer then try to chip it off with a plastic spatula ? Gently gently !

Multisolve sounds good, I have ordered some. Thanks for the recommendation, Grannyknot.

I find most sticky substance dissolves with lighter fluid. I often use it on oil splashes on my clothes as well as label residue etc.

Success! Used the hairdryer and a very sharp knife to scrape most of it off then lighter fluid for the residue.

Thank you for all of you suggestions.

Thank you for letting us know what works. I'm sure it'll come in handy one day!
