Hello. I have around 16 used shock absorbers that I purchased from BrickLink, all used. When they arrived, I cleaned them thoroughly with a Clorox Wipe. I spent about 1 minute wiping each one. Can the bleach in the Clorox Wipe rust the metal spring? Is there anything I should do to prevent rust? Thank you.

Bleach can cause corrison on metal such as steel. You could use a light oil to coat the springs to prevent rust. Be sure the oil used is plastic safe, particular ABS plastic.
