This is mainly for Californians and Canadian members but other feel free to chime in.
Some of you might know that DNA is banned in California and Canada. As with most things, there are usually some workarounds and alternatives.
It looks like we can still get some products likeMultimedia File Viewing and Clickable Links are available for Registered Members only!!  You need to Login or Register
Or we can use Everclear (grain alcohol)

For those of you who use DNA as part of you finishing, what have you been using instead of good old DNA.

Why has DNA been banned?

What will you use to dissolve shellac?

Just did some checking and to answer my own question:

the federal mandate that California reduce VOC emissions did not specify which sources of VOCs should be controlled. Denatured alcohol was put on the list because industry and stakeholders decided that it would be less disruptive and less expensive to eliminate than some of the other candidates.

DNA should really never have been on the list but it's one of those situations where it's easy to get on the list and almost impossible to get off.

This is why I was asking about what other are using as alternatives.
IMO DNA was never the best choice. The specialized shellac reducers/thinners are more strictly controlled and blended. You get a better quality finish using a better quality reducer.
For those of use who use shellac sort of infrequently, our supplies a DNA or whatever are dwindling or gone all together.

One site I read said to use isopropyl alcohol as a substitute. Was not talking directly about dissolving shellac though.

I found this:
Isopropyl rubbing alcohol is no good for thinning shellac because it contains about 30% water. The water will cause the shellac to turn white, or “blush.” If you have access to 95-to-100 percent pure propanol or isopropyl alcohol, you could use it for thinning without a problem
