This should probably be an FAQ. Is there any real difference between using a DA from a big box store that has 40-60% Ethanol vs one that has ~90%? I’ve decided to branch out from the “big Z” and mix my own. I’ll only mix enough to use so I won’t be storing it for a long period.

If you mix your own, why not 100% Ethanol instead? Denatured alcohol is so-called because it has additives to render it non-drinkable (according to Wikipedia).
How it functions as a solvent would likely depend partly on the non-ethanol ingredients.

I wouldn’t use alcohol that was less than 90% to dissolve shellac. I haven’t tried to use the lower proportions, but have read several times in finishing books that you shouldn’t, and it makes sense to me because if you have 40% DNA you have a lot of water in the rest of it, which will hinder the drying of the shellac.

I’ve read on many sites that 90% alcohol or better is what to buy. Any less and you risk blushing and whatnot.

Sunnyside brand denatured alcohol only has 5% water. The balance is a combination of ethanol and methanol. Coincidentally I phoned and talked to their engineering department this morning. I had to know so I could mix flattening/softener for veneers.
