adhesive removal

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

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.

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.

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

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

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.

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.

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

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.

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

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.

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!

Nail polish remover?

White spirit might work

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

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

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

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.

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.

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.

WD40 is worth a try.

Stick it back up?
