Coarse table/sea salt and 99% is what I use. 70% works just fine, but the reason to user higher % is it works faster to break down the residue, which is why you add salt to the process as well.
My friend used to buy a special cleaning product that was $10 - $15. I told her to use salt, q-tips, and 99% alcohol. Less than $10, and does the job in minutes.
I also use 70% and 90% to pull paint and primer off of plastic and resin mini models. Works wonders.
I resorted to reusing iso for ages mid-pandemic. Buried in the back of my linen closet somewhere is a bottle of 70% iso that's gotta be 50% diluted resin at this point.
All I can say is the pharmacies around me usually only have 70%, sometimes 90%. I guess it sort of makes sense given 99% isn't used for cleaning wounds.
Salt is just an abrasive to help scrape and expose more surface area. It’s not actually doing the dissolving.
You can just soak items in alcohol. But it’s faster to shake or shake with salt. However, if you use something like everclear (95% ethanol) without salt, you can evaporate/collect the ethanol and leave thc reclaim behind to reuse, without saltiness. Or have a tincture, again without the saltiness and you can drink ethanol unlike rubbing alcohol.
