Help - how do I remove the remains of very old sticky fixers?

[Monkeychopsmummy]

I removed an old mirror from the back of the bathroom door when we moved in but haven't been able to remove the remains of the sticky fixers - it is kind of a spongy residue - does anyone know how to remove it (with minimum elbow grease!)?

wd40

White spirit rings a bell for this type of thing

Don't forget to test a small hidden area first before ruining door - just in case the bells ringing are actually tinitus

definitely wd40.

Thanks - I think I have some white spirit so I will try that first.

The white spirit seems to be working - spongy stuff is coming off when I scrape it now - yippee! Thanks again.
