I've got a small problem with sharpening stones. My dad died last year and left me his stones. I have a double sided stone
that's extremely rough, a couple of diamond hone blocks (180, 260 & 360 grit) that look like they came from HF, a double
sided white and blue and a stone reading "Franz Swaty." All of them are loaded and have extremely shiny surfaces.
Is there a way to clean and/or save these stones? What's the proper way to use them..oil, water or dry? I've got a number
of carving tools, planes and power tools I'd like to sharpen but don't have any idea if these stones will work or are worth
the effort. R. Wink


Also, below (previously) in this NG search for the header:
"flattening Shapton stones - any alternatives to the Shapton plates?"
You'll see some good suggestions for flattening stones, which
I intend to try.

I think wd-40 is too thin, never done it, but saw someone else do
it and the stuff soaks right in when some should remain on top,
to be effective. He kept on putting it in frequently as I watched.

Point being is, the oil prevents the stones from clogging the way you
found yours and creates "slippage". I suggest as cheaper source that
will be effective, 3-in1 oil. You can get large sizes of it cheaply at places
like home depot or orchard supply hardware.
