Evening All,
I bought a tin of this a while back ( Pre-Lim Cleaner) but never really tried it until now and I have had some success with a roman bronze and a rose farthing which both gave surprisingly good results!! (I feel another cleaning video coming on!) But I was also wondering if anyone else uses it and to what degree of satisfaction are their results?

Snap, so would I. I’m not good at cleaning copper based stuff really.

Yes please to the video :thumbsup:
Yes I really don’t like Roman coins, I’m not joking

I suppose the type of cleaning would depend upon the desired outcome.

I have a George III Halfpenny that's sat on the kitchen table at the moment, it's possibly the nicest Georgian coin that I've managed to find to date. It has a few dodgy corrosion spots on it which is a shame, but overall the detail is quite decent all things considered. I'd love to improve it's appearance if there's a way.

The thing you have to watch out for is sealing in any moisture within the metal. Do that, and the coin will eat itself from the inside out and conservators use vacuum chambers to remove moisture content and so help prevent bronze disease.

Having said that, there's no harm in trying these things out on low- or no-value items if it improves their appearance or aids an ID and I'd also be interested in seeing what your gear will do :thumbsup:

Hadn't heard of this - thanks, although it does say not suitable for silver.

Yes I did try this after seeing it on your video. I feel it does lift the crud off of the coin which is what we want isn't it but I have not used it enough yet to pass a decent judgement. I didn't like the white powder after-effects, found that a bit of a pain to get rid of.
