Nail polish remover works too as an alternative to traditional rubbing alcohol, but may prove damaging to fabric. If you’re at all concerned whether it’s going to leave a stain of its own, do a test scrub of the nail polish remover on a part of your jeans that won’t be easily seen, such as the inside or the bottom of a pant leg.
Use some more rubbing alcohol and apply it to the stain if you’re not yet getting the results you’d like.
As always, remember to wash your clothes according to their respective labels.
It is generally recommended you use a blunt knife for doing this, as sharp knives run the risk of causing damage to the pants themselves.
Even if you don’t have any paint stains yet, it’s a good idea to keep an oil solvent handy so you can fix your clothes as soon as possible if it ever arises
Use a toothbrush if you think the washcloth isn’t working as well as it should be. If you think a heavier-duty chemical is needed such as industrial paint remover, it’s a good idea to test the chemical on an innocuous part of your pants (such as the inside of bottom pant leg) first before moving in to solve the stain. That way, if it’s shown to have damage, the damage will have been caused somewhere relatively harmless and irrelevant.
If you don’t already have some in your cabinet, glycerin is very easy to get and can be found at just about any supermarket.
