White Powder on New Car Parts - What Is It Really?

Update: I went with the compressed air method and it worked perfectly. Most of the powder came right off without any effort. I'm confident the parts are now clean and ready for installation. Thanks everyone for the advice!

The white powder is typically talc or clay-based, right? I read somewhere that you shouldn't let it sit on rubber components for too long because it can degrade the material over time. Has anyone experienced that?

Has anyone tried using isopropyl alcohol for cleaning this stuff off? I'm wondering if that would be gentle enough but still effective.

Following up on my earlier comment - if anyone uses chemical solvents, make sure they're compatible with the material of the part. I made the mistake of using the wrong solvent on an aluminum component once and it left spots.

Isopropyl alcohol should work fine. It evaporates quickly and won't leave residue. Just make sure the parts are dry before installation to avoid any moisture-related issues.

Noah, just because you haven't experienced problems doesn't mean they won't happen. Proper maintenance and preparation take time for a reason. Cutting corners is how issues develop.
