Best stuff i have ever used was ammoniated hand cleaner.Was back before we used gloves for hot mopping and it took the tar off pretty good.Stuff went fast and i grabbed the last container made it last a few years.
I would get greasy rebuilding an engine or doing cv joints or whatever auto related this stuff would clean hands so good.Wish i could find a similar product.Today best i can do is use dish soap then use a squirt of lemi shine it does pretty good.I have tried many hand cleaners most are ok
In my experience...On hands.....Wd40 works well as a oil base paint remover and oil, grease, grime remover as well but it does require a followup cleaning with a hand cleaner, soap etc. To get a final clean. Lanolin hand cleaners seem to work well without drying out your hands. As has been said previously...a brush is a necessity to get under finger nails and deep clean the all the pores.
Been a long time since I needed to get more so don’t know that they are open but Soap Man in Ventura has a kickass hand cleaner that’s easy on the skin too. It’s liquid with grit and works well. They also have an excellent concrete floor cleaner that would pull all the oil out.
