[Farmall] cleaning solvents

[Bob Currie]

Seems like as far back as I can remember, we've always had a 5 or 10 gallon 
tank of some kind to clean the greasy parts when we took things apart for 
repair. Soaking them overnight and then using a hand brush to remove the 
crud usually did the job. Within the last 5 years, I've noticed the solvent 
that I buy has less and less potency  and won't clean much of the 
grease.  The 55 gallon drum where I buy my solvent now says "mineral 
spirits" on it.  The guy at the parts house just shrugs and says "that's 
all we can get now days".  I'm wondering if it like this all over the 
country, or just out here in California where the EPA runs everything?  And 
what solution seems to work the best?
