Please tips to take off stickers and blue tack stuck on the wall/furniture

[Dorange]

That's it. I'm redecorating dd's bedroom and my nails and fingers can't take anymore.
I won't paint the room but I need to get rid of those bloody stickers, blue tack and its stain.
Any tips how can I do it more easily?

Haven't tried it but heard that hairdryer on stickers helps to loosen them. No idea on the blu tack though - good luck :)

Soak them in lighter fluid or WD40

You need 'Sticky stuff remover' by De-solv-it. It's available in John Lewis/Lakeland/many supermarkets. It's bril for that sort of thing.
