Where to buy MINERAL SPIRITS

[0007]

These days most "paint thinners" have an acetone/keytone base as in "lacquer thinner". Mineral spirits is something different and normally will not affect "hard" plastics. That said, it is always best to test a small out-of-sight/non-critical spot before using any solvent on any plasic.

You might consider parts washing fluid from the automotive store. I got mine at Napa, but if you can find a local petrolium dealer like one that sells oil to diesel shops, you might find it cheaper. I use it in an automotive parts washer I got at harbor freight. It's a good solvent that's safe for plastics, low odor, low flammability, and the jug says not bad on your hands (I still use gloves though).

It's expensive though, like $20 a gallon, but that will last a very long time. Most of the crud will settle to the bottom given time, then you're back to new fluid again.

The ONLY time I've ever seen a Glock that was too "dry" to operate properly was at a rental range that used an ultrasonic cleaner. The slide was extremely stiff to rack and it was jamming occasionally. A strategically placed drop of oil fixed it.
