If concerned about toxic chemicals, you can use nitrile gloves and make sure you're in a well-ventilated area when using.
I recently obtained a sample of Weapon Shield
which is a CLP which does NOT contain toxic chemicals (note: BreakFree CLP has some toxicity issues). That's one reason I wanted to try it. A CLP Cleans, Lubricates, and Protects from rust and corrosion. I haven't had a chance to test it yet but Weapon Shield has a very good reputation. It has a good reputation as a lubricant (looks similar to a good 10W-30) and I've seen a couple of informal rust tests where it has held up very well. A CLP product should take care of everyday cleaning needs.
