Over here in our corner of Almost-But-Not-Quite-Perfect, we supply hand lotion to our operators with dry skin to ensure that ESD wrist straps make good contact. Only the lotion that we supply is permitted in our shop (which is a periodic struggle). The point, as I understand it, is to prevent depositing silicones, which can be a bear to clean off. Doug mentioned a couple of sources for these lotions. And like Doug, we clean our assemblies right before conformal coat. But we have one operator allergic to aloe vera, and every ESD lotion I've seen has this stuff in it. Anybody know of an aloe-free alternative?

Almost certainly a sales pitch. It is supposed to enhance contact with the wrist strap, implying it is conductive and non-evaporative. Do you want to risk conductive and non-evaporative chemicals transferred to critical assemblies? The MSDS is particularly non-informative and I suspect the product is mostly water plus a fragrance, a dye and some form of surfactant. Probably a very expensive way of buying water. Have you tried my thumbprint test?
