removing stickers

[samuelcat]

There is an old sticker on the inside of my caravan window. It has dried out so wont peel off.
What can I use to remove it without damaging the perspex window?
Thanks

DIY store, sticky stuff remover where the sticky stuff is.

methylated spirits usually effective

Lighter fluid.

alternatively non-acetone based nail varnish remover (the bluish coloured one with no alcohol)

WD40 works at removing sticky stuff too :-)

To remove those self adhesive labels from anything plastic,
cover the label with ordinary cooking oil and leave for 24 hours or so. It does not affect the plastic at all.

Mayonnaise is good too.

WD40 does the job in seconds

and will not harm the plastic
