Tri-Flow with Teflon is a far superior product than WD 40,probebly just as toxic,but I just use mineral oil on my razors.

My old man used to buy it in 25 gal drums for his gunshop.
Parts would come out of the bluing tanks,Rinsed than soaked in a tank of wd,worked well.

DO NOT throw your WD 40 in the trash,needs to go to the Bio-hazard drop off place.:)

As above,mineral oil is all you need,and just do not get the pivot wet,no need to do so.

My Dad used to do that to his knees,but when he had two AK amps,he stopped.

WD 40 is made from recycled motor oil,thats why it is so cheap,Whatever turns your crank:) loaded with carcinogens.
