While looking at an article on Renaissance Wax, I came across this:

http://www.picreator.co.uk/articles/10_renaissance_metal_de.htm

Could this be used on daggers or would it be too harsh?

They have a couple of products that look interesting. I'll get some samples and try them out. They may be something we should carry here.

That's great Vern... the one in the link above looks particularly interesting.

I agree, the cleaner and the de-corroder look promising. Put me down for some if you order any, Vern!
Thanks!

As they are UK based and I am. I have just ordered three products. Wax, De-Coroder liquid and De-Coroder paste (pre lim)

I spoke to the owner and these products are supplied to the Royal Armouries. What better confirmation do we need?

There is also a main US supplier/importer in Florida.

Spock... any chance you can take some before and after shots after you've obtained the products? Cheers, Scott

Sure I have a couple of old prussian dualing sabres (practice type) that are totaly covered in rust, I will play with the iron cages on them. I will have the items ordered next week.

Vern:
Please keep us informed on these products. I for one am always looking for a better way to deal with corrosion.
Jim

I have samples on the way from the US distributer. We'll see how they work.

Hello.

My products arrived today. I have a parts Naval dagger that is in a poor state. I will be starting my first ever restoration project using the Picreator products. I have taken some before pictures. I will post as soon as I have some results. The Brass items are in soak now.

Looking forward to the photos.

Things are in soak. It turns out that the PRE LIM product is for use on large areas of metal. It does the same job as the liquid de-corroder and also has a very very mild abrasive action.
The liquid is for use on small parts, you just de grease them and drop them in, though it was suggested I do a test first on a small item and check in on the treatment hourly.
I removed some of the corrosion from the blade with 0000 wire wool and treated it with Pre Lim. The Pre Lim dried to a powder that I cleaned off under the tap. There was not a lot of difference. I am now going to test some more. I will stress this is my first ever attempt, you guys may have more success. The nasty looking brass parts (that were a dull dark brown colour) are in soak. Thats it for now.

pic3 what a beauty......lol

Hello.

So this is what it turned out like. The Brass fittings came out of the de-corroder a matt copper colour. I had no option but to treat them with another cleaner. The colour came back but I was a little worried. I would not immerse this type of fitting in the de-corroder again.

I used some of the Pre Lim on the scabbard it had little effect. In the end I used another cleaner with a tooth brush to get it clean.

The Pre Lim on the blade did not make much difference even after three applications. Though the blade was in a very pitted and rusted state. In the end I treated the blade to a hot wash and used 0000 wire wool and Autosol to bring back some polish, I feel it came out quite well.

The Pre Lim did quite well on the grip and I was pleased with the outcome. I am of the opinion that more testing is needed by someone with more experience. As I said earlier this was my first ever attempt at really going to town on an item.

pic3 final one, I may put this into an auction now to see what it fetches......lol even with a missing ring.

I think your first attempt worked out quite well.

Thanks......look at pic3 you can just make out the orange/copper colour I saw. in the low areas....

There's varied opinions on whether to undertake this sort of work or not but considering the condition it was in before, I think you have given it a new lease of life. It's all down to preservation methods now.

Congratulations, I think you have done a fine job there. That piece was definately rough & the result you achieved is remarkable! even more so considering it was a first attempt. I guess there was not much to lose there but I would still have been a bit anxious myself.

Doesn`t even look like the same piece now

What I'm interested in is if there is an effect on motto's, that is, would it eat them away some what?

I do not think it is corrosive at all. IE not an acid as such. If it used by the Royal Armouries then I have no concerns on ferrous metal. Brass I would avoid. It is the same dagger........Honest....all I need is a lower hanger mount....anyone have one? Not concerned about the condition :-)

I was wondering if some of the otherguys have tried out these products?

Vern or SDP ?

I have a very coroded HJ knive that I want to give a clean. I would rather give a (soaking) bath then some rubbing?

Hi Joe, sorry, I haven't used this particular product myself, however, Spock seemed quite happy with it.

I think the results are very good on the dagger treated. I think you did a great job, as previously stated : a new lease on life" !!!! Tiep

spock,

I just received a little fail of the metal decoder.
But you say that you soaked your stuff.
How did you do this, if I really have to put a blade to soak then I'm afraid that I have no product left.

I noticed that the de-corroder is a bit gelly, so instead of soaking it, it brushed some product on a bad blade, but with little result.
So any help how to use is properly is welcome.
