I found out about it on the Forestry Forum. They make the log rite can't hook that I use and after all the posts about how good Blue Creeper works I decided to try it. Mostly for the low odor that is non toxic. Really amazed me by how little it takes to free up rusted items, especially things like lugnuts and no toxic outgassing. You just need a couple drops and wait a couple minutes. If it doesn't break free a couple more drops and usually that's it. I use the sewing machine oil on all my CNC machines and things like squeaky hinges in the house where you don't want fumes. Really great made in America products by a small business. My wife has a little bottle of each now and takes care of the house squeaks without bothering me.I too have never heard of "Blue Creeper"
Reviews are all very good,.....for sewing machine lubrication.
I have been using Kroil, as a penetrant, for many years, with phenomenal success.
Blue Creeper sells for $4.20 per oz.
Kroil sells for $1 per oz. ($128 per gallon)
I bought a full gallon of Kroil.
A gallon of Blue Creeper would apparently be $4.20 x 128oz = $537.60 ?
I shall pass on Blue Creeper.
I have multiple penetrant needs.
I only have one sewing machine!
