i know i shouldn't re use them. but im a junkie and that's what i do. but any way the other day my plunger got stuck and popped out of the black thing inside. so after slowly and carefully pulling out the plungers i lubed the black thing with a very small amount of brand new . i made sure there was nothing on the black thing on the plunger. Then i submerged it in water. After having the plunger back in the rig i cleaned it out with water before using.
My question is that is it safe to use chap stick to lube the rig? i used it couple of times and it works great now. but what are the dangerous? can it get into the blood? And what do you use to lube your rig?
