My favorite penetrating lubricant spray
This stuff works great. It sprays and stays - doesn't drop a lot from where the intended location is. You can see it easily penetrating. Can't say how much better of a lube it is; they say 3x more lubricant than other products. That doesn't really mean anything in and of itself. The SDS says 30-60% hydrotreated heavy naphthenic petroleum, so that's a starting point. 1-5% SbDTC as well as a useful additive. Other products Ive looked at that are competitive seem to only have 10-20% heavy paraffinic lubricant in them, but they have a good quantity of "light" cut which may also lubricate and protect. Bottom line, I think this is the best penetrating and lubricating spray Ive used. There are some that are cheaper and more available, which should be considered for some applications. But they also seem messier and don't always creep in as well. This is good stuff.

Amazing stuff.
This stuff is not WD-40. I am a fan of WD-40 but penetro in a can is a different situation. If you have a squeeky door, and you spray this stuff on the hinges, you will not only have a non squeeky door, but the door will flip open and swing with the velocity of a Nolan Ryan fastball... If you could figure out what they put in this and just put it on everything... I'd spray it on pancakes if I could. This stuff is amazing. If I am having a bad day I just spray some of this on my butt and things just get smoother. I am so impressed, honestly... I just walk around my business and randomly spray hinges, joints, or anything I want... it is therapeutic for me. DO NOT spray it in your eyes.

This is the absolute best penetrating oils in the market.
I have used plenty of penetrating oil in the past and none have compared to Sheffield 90 it’s the best.
