I have tried as many sources local and online and find that Calfornia has banned the sale of denatured alcohol. Although the CalEPA was mostly concerned about its use as a fuel, what are woodworkers supposed to do?
I am on my last few ounces of the can I bought at Home Depot in 2022. I have about half a can of Zinsser clear left. I usually cut it to get a 1 pound cut for final work. There is not any substitute that I know of.
Does anyone have any place to get it?
I too am frustrated as I will run out in a year or so. My suggestion is to contact professional furniture restorers. Likely though what they use will be expensive. Alternatively you can use Everclear or similar 190-200 proof alcohol. Again expensive though.
Crazy world we live in.
The solution here in SoCal: Arizona. 
you can still pick it up at TH&H. The laws literally don’t apply there. Small supplier loop-hole or something like that (no joke).
Hi Will
Went there. After 5 minutes searching, finally found they had one gallon left in the store. That would last me longer than I want, and be hard to store. Maybe later they will have smaller quantities.

ShellacFinishes.com sells 200 proof denatured alcohol right here in San Diego. It is listed on our Sponsors page, a subpage under Resources. They are an excellent company. Shop localo!
Thank you Tobias, I have been buying flakes from them, didn’t notice the alcohol. Wonder if he’ll ship out of state…. I’m no longer local… but I sure don’t miss the heat you all have right now…
