This is my first time trying shellac. On my 3rd coat, one cut with
alcohol, the finish dried on part of the piece with milky white streaks.
Tomorrow, I'll snad them off and reapply, but I want to know why, of
this happened out of the several other coats I put down. The shellac
was thinned with alcohol.
Thanks for any suggestions

I still use a rag for applying shellac, but I haven't done any
fancy furniture with it so it hasn't been a problem.
You can clean the cloudy shellac off with straight denatured alcohol,
let it dry overnight to let the moisture finish evaporating (although
the alcohol will gather a lot of it) and try again with a clean brush.

Next time don't "clean" the brush. Rinse it in clean denatured alcohol
and let it dry semi-hard with a small amount of shellac on it. Save
the brush cleaner solution to mix new shellac. The next time you use
the shellac, let the brush sit in it for a minute and it'll be good
to go. Shellac is very easy to work with that way.

Could also be trying to apply too many coats at once, particularly if it is
humid. FWIW, not a bad idea to clean shellac brushes in the same solvent you
used to thin it ... and they don't have to be totally free of
shellac/perfectly clean, as long as you're planning to use them with shellac
the next time.

That's what I thought, thanks. I was thinning with denatured
alcohol, however I was cleaning the brush with ammonia and water, and I
must have left some water in the brush.

Sounds like moisture in the process. You didn't use household
alcohol (70% Isopropyl, 30% water), did you? If so, toss it
and melt more flakes with denatured or anhydrous Iso.
