Thread: Is this Cell Rot ?

Here it is:

To me it does not look like cell rot.

Those two are examples of cell rot

I do not have a good nose, but I do know that cell rot will give off a vinegar smell as it deteriorates and give off gas.

WillN is right - if it has been in a confined space for a while you can usually smell it. It is either a vinegary smell or faintly 'medical' smell like camphor. I say 'usually' because sometimes it has no smell.

The smell varies according to the type of celluloid - some are made with acetic acid (very early), some with nitric acid, some are made with a mixture of sulphuric and nitric acid and some, if not most of the post-cellulose acetate era, have camphor added.

Celluloid handles with a pattern, for example mock tortoiseshell, show that they are undergoing cell rot because the parts of the blade under the clearer areas get light rust on it which gets more serious as time goes by, and the dark areas usually have so much filler in them (they used asbestos! among other things to make the dye appear more solid) so the breakdown of the celluloid does not occur so heavily in these darker regions and consequently the blade is not attacked as much.

The type of handle you have generally out-gasses (nitric or acetic acid) all over the blade equally so you do not usually have any darker areas of rust at the onset. Given time though, the bottom half of the blade will turn darker and rust through. At the onset it will look like the whole blade - even past the scales - has been 'misted' with a fine corrosive spray.

There is more info here in post no. 19.

Thank you very much gentlemen!

Any ideas on how to remove the rust?

I would try any good polish such as Mothers Mag & Aluminum. Sometimes it takes a little elbow grease too but the results are well worth the rewards. Keep an eye on it and if later you do suspect cell rot the only cure is new scales. For a while I would keep the razor away from others as a precaution as cell rot will spread. IMHO, you don't need to worry but 'better safe than sorry!'

No celluloid rot as far as I can tell. What I've seen is that it's 'bubbly' in nature, pinprick coverage. If that makes sense.
