I recommend a mix of rubbing alcohol, baking soda, and salt, and shaking that around in the utensil.
if you use a very strong rubbing alcohol, the baking soda and salt will not dissolve.
I believe that is desirable. You are using them as abrasives to help scrape resin off mechanically, aiding the chemical breakup by the alcohol.
This is correct. If you make a supersaturated mixture of 91% isopropanol and salt, the 9% water will dissociate the salt ions a little bit but they will not dissociate/ dissolve in the alcohol.
Assuming there is nothing non-volatile added in, yes. Bitrex is sometimes added to methylated spirits.
I have found a rinse with acetone followed by NaOH solution to be most effective.

Use non-acetone nail polish remover with ethyl acetate in the ingredients list. It's like magic. You need to do an alcohol wash to get rid of the taste, though.
I have heard of many pipes being successfully cleaned with acetone. Some people even save the wash, evaporate away the solvent, and use the resin.
Yes.
