Gideon Posted October 21, 2014 Share Posted October 21, 2014 Hi I have a few non-valuable fossils I am going to practice sealing in paraloid to hold back, or prevent decay. However, a couple of them already have patches of rust and decay on them. Would it be enough just to scrub them well before sealing, or would they need some specific treatment. I have a tub of Kurust rust-remover I use for the car. I was wondering whether I could apply this to convert the rust, then scrub clean before drying, and treating with paraloid. Any suggestions or warnings would be greatly appreciated. Thanks Link to comment Share on other sites More sharing options...
Adam.morris08 Posted October 21, 2014 Share Posted October 21, 2014 Some people use ammonia to neutralise the corrosion as it's usually acidic due to the suplher released from the breakdown. Link to comment Share on other sites More sharing options...
Ptychodus04 Posted October 22, 2014 Share Posted October 22, 2014 I soak in Iron Out then scrub, dry, and seal.

Gideon Posted October 24, 2014 Author Share Posted October 24, 2014 Thanks guys. I'll test a few theories on my box of bits of fossils and see what happens. Ive already stained my hands blue with Kurust, and spilt acetone over my hands and sideboard. Link to comment Share on other sites More sharing options...
Gideon Posted October 24, 2014 Author Share Posted October 24, 2014 Update - I wouldnt recommend Kurust rust remover. It works great on cars, but not ideal for this job.....it turns rust black, so darkens many areas of the pyrite. Link to comment Share on other sites More sharing options...
Ptychodus04 Posted October 24, 2014 Share Posted October 24, 2014 Try the Iron Out. Mix with hot water (about 1cup per gallon of water) and soak pyrite for about 4 hours (overnight is better if you can). The pyrite will come out black. Never fear, scrub with concentrated Simple Green or liquid dish soap and a tooth brush. The black goes away and leaves nice clean pyrite behind once rinsed with water. 2 Regards, Kris Global Paleo Services, LLC https://globalpaleoservices.com http://instagram.com/globalpaleoservices http://instagram.com/kris.howe Link to comment Share on other sites More sharing options...
Gideon Posted October 25, 2014 Author Share Posted October 25, 2014 Thanks Kris I've ordered the UK equivalent of Iron Out via ebay. Link to comment Share on other sites More sharing options...
Ptychodus04 Posted October 26, 2014 Share Posted October 26, 2014 Make sure you don't soak the stuff in your kitchen if you have a significant other. The smell will cause an argument... Says the man with first hand experience! Good luck. Once you get them clean, let them dry for several days (or even heat slightly in oven as suggested in another post on forum). Then once you seal them in your Paraloid solution you should be good to go.
