Masking tape welded to glass

[Dec66]

I've been painting some garage doors with glass lights in them. I masked the panes off to stop them being covered in paint, but now I can't get it off without leaving gummy residue on the glass which is a bugger to shift.

Can anybody suggest something to remove the gum without affecting the paint?

Solvent cleaner (electrical cleaner, general purpose cleaner, pvc cleaner..almost any will do) will break down the glue but not sure about the paint. You can buy aerosol cans of label remover...that will obviously break down the glue but again...the paint ?

If I used either, I'd probably apply it to a cloth or similar to prevent too much cross contamination to the paint.

White spirit should shift it.Or maybe acetone.

I always keep a bottle of isopropyl alcohol in the house for that sort of thing. Usually works.

I would leave the paint to harden for a week and then attack the gummy residue with nail varnish remover.

Is the glass flat? WD-40 is good at removing residue, as are baby wipes

A steady hand and then you don't need masking tape

WD40, then washing up liquid to get rid of the WD residue

A blow-torch might shift it (but there could be 'collateral damage")

wd40, gt85,.... both will shift the sticky residue

+1 for WD40. It's good for removing decals from frames as well.

I work at a printers and we use isopropyl alcohol and methyl ethyl ketone (don't try and get or use this) at different ends of other things.. If the residue is strong then alcohol will do little, we have recently started using some strong double sided tape for a process which leaves a lot of residue, and after getting some aerosol canisters from planet x recently as they were much cheaper than normal - I have to say that their jobsworth brake disk cleaner is awesome for this purpose... And it doesn't kill you quite as quick as MEK either..

Razor blade scraper.

Buy new windows

But as said ,let the paint harden fully then most of the above.​

+1 for the razor blade scraper.

I've invested in a plastic thing that you hold against the edge you're painting up to. Hopefully I'll never need to use masking tape again.
