Hi, Shawn.

I use CLR on a Q-tip to remove rust, and rinse off the CLR with
isopropyl alcohol.

Rather than hassle with nitric acid solutions I use computer board
etchant that you can purchase at any Radio Shack
(http://www.radioshack.com/product/index.jsp?productId=2102868). Dab
it on with a foam brush and rinse with warm water, followed by an iso
alcohol rinse and a couple hours in the oven to dry. After it's dry I
apply a light coat of automatic transmission fluid. I don't use
lacquer because if I don't want to seal anything in by accident, and I
prefer to be able to quickly re-clean if needed.

Here's a small Campo slice I recently rehab'd, it came out great!

Best,
Michael in so. Cal.

The first one is I know some people seal their iron slices with a clear coat lacker, now is this safe to do if done right, and if so, what is the producted used. If someone wants to take it off the clear coat what can be used? Could acetone be a good agent to take off the coating?

Also if there is some lite rust on the slice, whats a good agent to clean off the slice before etching. Why I aske is because I have an iron that is etched on one side and on the other side its kinda etched with some cool looking saw marks but could be etched more. I would like to have both side etched nicely and see what peoples thoughts are.
