Listerine contains thymol -a potent fungicide.
That's why papilio28570 can keep his specimens in the relaxing chamber for
a month.

ok, just to say the isopropyl alcohol in the relaxing box did get absorbed into the wings and they seemed pretty wet and sticking together even . But they quickly dried to normal on the spreading box with no residual staining.
But the muscles were't more relaxed than with water .I also injected a mixture of alcohol and water and it didn't make a difference than just water either
Overall I found the general handling more difficult with alcohol than just water , with more danger to rip the wings

Have you tried injecting a very small amount of boiling water into the thorax?
I leave all specimens in the relaxing chamber for only one day.
Small specimens are ready for setting after one day larger ones I inject.
You could inject without relaxing first but this means only the muscles are relaxed, not the wings.
Wings damage more easily and are less easy to flatten but it works great if you have to set large amounts of specimens for example for decorations.
I have only used alcohol for other insects but I know people who use it in the relaxing chamber as well.
In addition I take all specimens out of the envelope and put them upright in the container.
This way the body touches the wet towels but the wings don't.
Hope this gives you some ideas to experiment with.

yeah, I also inject boiling water. But I think by the time I get it into the seringe and inject it it might not be so hot anymore.
So far the best method is to leave it 1-2 days in relaxing chamber and if it's still stiff inject water and wait again
But I never inject water before it's partially relaxed because I could break the thorax getting the needle in.
I guess papered specimens can't always get as soft as "freshly killed"

If you boil it right before injecting it should still be hot enough to soften the muscles even if it cools a little in the syringe.
Like you said the problem could also be the kiling agent.
In some tropical countries or remote locations it's difficult to get the right stuff and people experiment with whatever they can get their hands on.
As someone pointed out earlier, you could stab or cut the wing muscle.
I do this (cutting)in large Hepialidae and it does help.
