hey guys i have heard of people using mineral oil on aluminum oxide stones specifically i have a cheap aluminum oxide by norton that i got in home depot for like 7$ just curious isnt regular mineral oil too thick? i think there is a few kinds of mineral oil dont know wich 1 would be right i think regular would be a little to think can you thin it out with something? also i have heard "simple green" being used as a lubricant i use the concentrated spray of simple green to clean the few stones i have most of the time just a few sprays and warm water sometimes i let it soak in water and a couple sprays...are you supposed to just put the concentrate right on the stone for lubricant or mix it with water?

I cannot speak to the questions regarding Simple Green. I have also heard of Windex being used on these stones.

You can use all manner of thinner oil. Clear lamp oil is thinner and works OK, as will all kinds of industrial oils. I use mineral oil because it works fine, is ingestible, is common enough to be found everywhere and is inexpensive. Being a tiny bit thick is alright as well, it stays on the stone a bit longer and theoretically can float more debris. Some forms of baby oil are a thinner viscosity than the laxative grade stuff and might be worth a try. At my Home Depot they sell a thin mineral oil made by Norton - in a small can right next to the stones:)

IMHO the oil has to be pretty thick to interfere with how the stone works, something like Castor oil.
 
Baby oil is a bit thinner (and scented; may be good or bad, depending on preference. ;)).

Regarding Simple Green, I tried it a while back with my Norton Economy stone (silicon carbide), picked up at Home Depot. Initially, I liked it; however, I later figured out it's somewhat caustic, more so in full concentration. MSDS shows 'sodium citrate' at ~5%, which is somewhat alkaline. In sharpening some carbon blades (non-stainless) with the SG on the stone, I later noticed some rusty spots on the blade. At full strength, it's also pretty rough on the skin, if the hands have been wetted with it through a sharpening session. May be a great cleaner, and it smells nice; but possibly overkill for use on a sharpening stone as a lubricant. I've since decided basic liquid dish detergent and water are more user-friendly for these things, both for lubing the stone and for cleaning it afterward. :)

I've also tried Windex, but it evaporates too fast in the dry desert southwest...

I use coon p oil. Its very stone friendly. You can order it online from smkw. Stones recommend oil or water, most oil. Idk why people use chemicals. That's not good for the stones.
