sound Posted June 21, 2014 Posted June 21, 2014 OZjohn,Missed this interesting thread having been away. Thought the results vindicated your decision to clean. Could be argued that it's not really cleaning but preservation.Just wondered whether you care to explain what product you used quantities etcRegardsMark Quote
Benny who Posted June 21, 2014 Posted June 21, 2014 The best way to start with this is to let the reaction begin slowly,with warm water.Then if not much is happening increase the water temp for a quicker reaction,and wash of any remnants with distilled water,rather then tap water to prevent water marks,or other foreign material sticking to the surface.Definitely a better looking coin now,with no real harsh treatment to the coin. 1 Quote
ozjohn Posted June 22, 2014 Author Posted June 22, 2014 Hi Mark,I used sodium bicarb plus salt in hot water with aluminium foil in the bottom of the dish. I tried to make the solution fairly weak so I could control the reactionby removing the coin and then washing it. I did this about 3 times (hard on the fingers with the hot water) until I was happy with the result. I looked around atvarious commercial silver dips to see if they would be suitable but most contained sulfuric acid which I thought would not be very good for coins.Johnj 1 Quote
sound Posted June 22, 2014 Posted June 22, 2014 John,Thanks. I have some old low grade silver that I will try it on. Thanks for sharing.Mark Quote
Peckris Posted June 23, 2014 Posted June 23, 2014 Goddards contains uric acid rather than sulphuric acid if I remember right. Quote
ozjohn Posted June 24, 2014 Author Posted June 24, 2014 You are probably right but I could not find Goddards locally and all I could get were various preparations offered by chain jewelers which all contained sulfuric acid. Funny thing is Goddards used to beavailable from discount stores in Australia but no longer it seems. Even the polishing cloths seem to have disappeared. Quote

Peter Posted July 5, 2014 Posted July 5, 2014 If no one has had it it is hard to explain.I'm sitting here with a constant pain.A sheet will cause me agony.At least the pain stops me from going for another beer. Quote
Rob Posted July 5, 2014 Posted July 5, 2014 I've never tried gout, however, I can recommend red wine, red meat, oily fish, cherries, white wine, beer, plus a host of cheese varieties. Water I cannot recommend, as it is a poor substitute for item no.1. Quote
Peter Posted July 5, 2014 Posted July 5, 2014 White rum is meant to be Ok but last time I missed the footie and had 2 cats sitting on my head.We have just got a new feral(he would of been drowned)...Going to try to go to bed. Quote

Co-codamol is the best thing I've found for pain, if you don't mind a bit of constipation and going ever so slightly doolally. It does work though... Quote

Co-codamol is the best thing I've found for pain, if you don't mind a bit of constipation and going ever so slightly doolally. It does work though...They just don't put enough codeine in the over-counter version (8mg I think it is), though it's better than nothing and, I agree, it does pack a punch!Don't forget folks, co-codamol contains 500mg of paracetamol per tablet too, so two of them is your paracetamol lot!You could always add ibuprofen to the cocktail, if you're desperate, AND you've taken them before!
