I have some new Japanese water stones that I use for sharpening plane irons and chisels but I also have some old arkansas stones. But over the years these stones have gotten all clogged with gunk after being used. What is the best way to restore this type of stone or is it not really worth the effort?

Let them soak in mineral spirits.

I had some super old really gunked up stones. I brought them up to the kitchen sink used some Dawn and a Scotch Brite pad and got them looking like new again. Need to flatten one as it’s a bit dished but it’s clean as a whistle.

Simple green and some type of scotch brite type pad has worked well for me.

It is worth the effort. Try mineral spirits. If that doesn’t work I’ve had luck putting a few rags in the bottom of a pan (or can) and boiling them for a while. The rags keep the stones from bouncing off the bottom of the pan and chipping as they boil. Pour off the funky water and refresh with clean water every once in a while. I like to let the stones cool some when adding fresh water to avoid temperature shock. I’ve heard of people who’ve run stones through a dishwasher cycle but the same people caught hell from their partners for leaving an oily film on the inside of the dishwasher.

Yes, I agree it is worth it for several reasons. First, I don’t think the current stones are as good as the ones from several years back—simply a matter of using up a finite supply in nature; and, second, there is something nostalgic about the old Arkansas stone if you’re like me and started with them before water stones became the fad and before diamond stones even existed. My solution was not the most economical and took several years before I finally pulled the trigger, but I purchased a DMT Dia-Flat Lapping Plate (c.f., ) and have not regretted it one little bit. The DMT Lapping Plate renewed the dished out and clogged Arkansas stones that I’ve had since the early 1970s without much effort and I use it to keep my water stones true after each use—it’s amazing how much water stones dish out with even a single use.

I have had a Arkansas white for over 15 years now. I use cheap carburetor cleaner for an instant cleanup. Spray on and wipe before it evaporates. In between, after each use, if you wipe it with sawdust, you may have to clean it once a year or so.

If they are old I would check them for flatness before investing any time in them.
I got ahold of some of my Dad’s old stones and they were dished so bad I couldn’t use them.
I don’t know what the heck he was using them for I guess knife sharpening.

I flattened a green Arkansas Stone with my DMT blue dot diamond stone. I used Gojo as a lubricant which pulled the oil out and at the same time cleaned off the diamond stone. After several hours the Arkansas stone was absolutely flat, but the diamond stone was incredibly smooth. It wouldn’t cut anymore. I called DMT and was told that the DMT diamond stones are for metal only, and the DMT DIA-FLAT lapping plate is specifically designed for to flatten sharpening stones. HillbillyShooter above has it right. I’ve used the DMT diamond stone to flatten water stones for a long while, but the Arkansas stone killed it. By the way, the DMT stone was brand new.

Would DMT warrant the diamond stone or were you left SOL?
