Ran across this when I was looking at some badly environmentally damaged Buffalo nickels. I've never heard of it and wondered if any of the CT members have experience with it. Appears to be no more damaging than acetone soak. http://vi.raptor.ebaydesc.com/ws/eB...ategory=11953&pm=1&ds=0&t=1522266575000&ver=0 Use directions: https://wonderoil.com/safeclean_use_instructions
I don't know about the chemical composition or activity level of this stuff, but based on the instructions you linked, it doesn't look like the folks developing it know much about coin conservation. I'd be extremely hesitant to use it.
My thoughts too, and I wouldn't use a brush and would only do some junk coins to experiment with it. I'll wait for more possible feedback, but thanks JeffB.
I don't see any obvious evidence of cleaning from their photos, but I would never recommend using any of these types of products unless it's super dirty, but, as long as the Buffalo Nickels have very little value, you don't plan on grading them, and they're just dirty, normal Buffalos, you could give it a try. From the description, it doesn't sound like the most legitimate product, but you never know if it's at all useful unless you try it.
From the description, it sounds to me like soap that's optimized for biodegradability instead of coin safety. It might be fine, especially if you rinse the coins very thoroughly afterward, but I don't see what would make it better than standard dish detergent. (Edit: since you're living off the grid, biodegradability might be more important to you. Fair enough.) I did find it interesting that the instructions mention using VerdiCare afterward. @BadThad, are you aware of this SafeClean product? Any thoughts?
Well, they conserved a couple of circulated 1964 Nickels with it so that makes it worth it right there...
It's been around for years. He basically stole my ebay description and layout when I sold VC there. Based on the description, it's likely a self-emulsifying veg ester or sulfonate. I've never tried it or analyzed it in the lab, so just a guess. Apparently it works well in certain applications because he has a ton of feedback on ebay. More concerning is the seller seems to specialize in selling nickels on ebay.
