If you buy a bottle of Everclear 190 proof vodka it is nearly pure alcohol when freshly opened. Naturally as time goes by and the bottle is repeatedly opened it will absorb some water.
I have successfully used the slightly dampened cloth and a warm iron method to fix this. Must very careful, but as stated, the issue is moisture trapped just below the surface. It must be softened and allowed to escape before the finish re-hardens.

You have to buy the fuel grade alcohol? Didn't they discontinue denatured. My can of denatured is so old it probably has absorbed water.

A cloudy finish is water trapped in the finish. Isopropyl/rubbing alcohol has water in it. the alcohol softened the finish and the water permeated to cloud the finish.
Denatured alcohol will soften the finish and draw out the water as it evaporates. Don't use too much. Dampen a cloth and lightly wipe it on, then wave the cloth over the area to aid evaporation. This is how one removes white rings in a finish. It works for shellac/varnish finishes too but you have to be extra careful because the alcohol will dissolve the finish faster.

I stupidly got a dribble of rubbing alcohol down the from of the stretcher. It clouded the finish a looks white. It's like when someone sets a drink on a wood take and it leaves a ring,
I forget what lifts the white but there is a way?
