Remove Old Oil And Rust Without Removing The Paint... Any Ideas

[Wizcrafts]

If you identify where you are located, it sometimes makes answers to your posted questions more meaningful, if the responders actually note where you live. In most cases, it means little to nothing. But, if somebody in Europe makes a request for where he or she can buy parts or machines and a person in the USA thinks that this person is also in the USA, his or her answer may not apply to the person asking for assistance.

One way to avoid confusion, which is used by a lot of members living outside the USA, is to simply mention "I live in {your country} and am looking for a supplier of parts for my {brand / model} sewing machine. This way, a person replying in the USA will not necessarily refer you to a US dealer (who may or may not be willing to handle the paperwork and packaging required ship overseas). Americans are not always familiar with European import taxes and the VAT that gets added to all parts and machines imported into these countries. The prices that we are used to paying in the USA can easily double or triple when shipped overseas.

Thor, at the risk of being berated for keeping off-topic, I have no idea what GT85 is, never heard of it out here. Dupont Teflon spray was brought into the country some time ago but was discontinued. When queried about it by people constantly looking for it they were told that there was no demand for it so wouldn't bring it in! As for Johnson's Paste Wax, many have looked for an equivalent but again, there is nothing that is quite the same out here (I have compared the MSDS on many products and can't find a match).

With regard to the OP, rust stains can be a problem due to the fact that they often get into the paint surface. Sometimes they can be polished off, but with anything other than kerosene/WD40 type stuff you run the risk of the paint lifting too. Electrolysis is a good way to remove rust without damaging the metal, but if the rust is under the paint then again the paint will probably lift.

I'm going to talk about this product one last time renaissance wax polish was invented in the 50's by scientists at the British museum at the palace or some such they wanted something that worked better than what was being used. this is what they came up with. they kept it for over 20 years before they let anyone know about it. the use it on most everything. leather medal glass paintings paper I hate saying this but you need to at least look it up if no try it or I feel your just narrow minded . some one here says if we don't share what we learn we will know nothing I feel if we as men never shared we'd still be in the caves here in the USA its used at the Smithsonian .NRA and several colleges and museums around the country so get over it

I'm sorry, thunter, are you referring to me? If so, I'm well aware of Renaissance Wax, and have been for many years. It was primarily developed for coating blades - swords, knives etc - for display purposes in museums. It is sometimes used by knifemakers/bladesmiths.Some museums have used it to try and preserve leather book bindings, but have found that it can cause long-term problems on leather. On metal, however, it does work well. If you're suggesting to use it to try and remove rust stains, then it's worth a try, I guess (although it does tend to be on the pricey side) but I doubt it will be any better than a good quality wax-based polish.

It is intended to be a preservative, not a cleaner (although it does contain white spirits, a solvent).

They make a rust remover

[dikman]

Yep, although they call it a "de-corroder". After a bit of searching I found that the active ingredient is Citric Acid, which can be bought pretty cheap at supermarkets etc. Nothing special about it, I use Citric Acid to clean my brass cartridges in my tumbler.

The main problem, in this case, is that it is a very slow process because it's such a mild cleaner. It's pretty difficult to get it to stay put on vertical surfaces so it can react with the rust, generally these sort of cleaners work best when the object can be immersed in the cleaner.

Well this must be the longest thread I have ever had....

Anyway, the machine is stil not here, but when it arrives I really want to try coke... So will try that just for fun and then try Darren's suggestion of wire wool and kerosene..if not then WD40....

Thanks, I have learnt something, which hopefully I can use in the future, because I am sucker for machines I don't need...

Cheers
