Removing Retouch Varnish

What do you use to remove retouch varnish.

I have a painting I did a year ago and it is still wet to the touch. Why??
I had sprayed it with retouch varnish. I've never had that problem before.
Anyway, I thought I should remove the retouch varnish but don't know what to use.

Re: Removing Retouch Varnish

The paint should have been dry before you applied the varnish in the first place...

If the varnish is a removable sort then a lint free cloth dampened solvent could be used to remove it, but that might remove the paint too. It will remove the paint if the paint is not fully dry.

It's not easy to keep an oil painting wet for a year. All I can think of is contamination of the oil by a non-drying oil or lots of retarder like clove oil. I've read on here that water miscible oils can stay tacky for long periods.

In a worse case scenario you could frame the picture behind glass and accept that it will remain wet forever.

A year?

Wassie, most retouch varnish is thought to be made from dammar, which would mean you'll probably have to use turpentine. If you don't have any turps then try mineral spirits but it may not be strong enough to properly dissolve it.

Your retouch varnish might be made from a modern synthetic resin, in which case any mineral spirits will do fine.

A previous thread and some tips that might be helpful: Safe Damar removal

Quote:
Using a lint free cloth dipped in [spirit], start in a small corner and gently rub the surface of the painting. The varnish will dissolve onto the cloth. If any colour is seen on the cloth then you must stop. Work your way across the entire surface of the painting in small squares. TIP: Keep using fresh pieces of cloth to ensure that the varnish is being lifted and not just spread.
...
If in doubt, give the painting one last rub with [spirit].

Golden (the acrylic maker) also suggest, for their MSA varnish, laying a solvent-soaked cloth onto the painting for a few minutes before you begin the rubbing procedure. Worth testing this out on a small area, see if it makes any problem with colour coming off on the cloths worse.

You don't need to remove the retouch. Being in Las Vegas, have you placed the painting in the warm sun for a while?
