Cast iron stains

[blanning]

I recently bought a lathe from grizzly.  So far I love it.  But it has one minor problem.  The way it's shipped, the cast iron legs are stored on top of the bed in the crate.  This has caused a stain on the bed.  It's smooth as glass.  So it's just a discoloration.  I tried some rust stain remover that came with the Boeshield.  And it helped slightly.  But nowhere near enough.

Is there a good way to clean these kinds of stains off of cast iron?

I don't know of a way. I had a leaky roof in my shop and my saw ended up with a couple of rust stains. I grabbed my RO sander and proceeded to start with a little coarser grit paper and progressed through the finer grits. Followed up with some good wax. The stains are still there but it is clean and smooth. Adds character.

I don't really think there is or at least I haven't found it. I have a Grizzly table saw that had some rust spots and I was able to get the rust spots off with WD40 and and gray abrasive pad. It's as smooth as I could ask but I can still see the discoloration. As museumguy says, it's character.

My Uniasw has a few from its previous life....yup, character.

I saw this from the Wood Whisperer the other day. Not sure if it helps. I am watching this discussion closely since I bought a new Sawstop a while back and it seems like every time I touch the surface it leaves a blemish.

Thanks, this looks good.

I have some older machines that need some help.  This looks good for that also.

Blanning, if you try it I would be interested to hear about your results and impressions. 
FYI. There was a comment under the YouTube video about it destroying the hook and loop pad on somebody’s festoon sander and they weren’t very happy about that. So maybe do some checking on how to protect your sander pad.

If you press down to hard you'll generate enough heat to mess up the velcro.

^^^^^^^that's the reason a lot of folks have to replace their pad so often.
