mackie,

No I haven't, although it sounds like a great product for rust removal. I would be concerned, however, about leaving a str8 razor in it for 30 min. to 24 hrs. --esp. one with gold etching. Do you think a shorter duration would accomplish the same result? Perhaps 10-20 minutes?

Is there anybody involved in restoration work at SRP who is willing to test this product on a rusted str8 razor blade and post the results?
