Best way to clean black rubber mask?

Best way to clean black rubber mask?

Best way to clean black rubber mask?

(OP)
Hello

I have a black rubber darth vader mask that I came across while going through storage.  The mask has a white film/residue all over it.  The residue is not thick and is spread over the mask in an uneven pattern.  The distribution is uneven, but generally the entire mask is covered.

I have tried to clean it with water, soap and water, scrubbing with a coarse brush.  But it does not seem to help at all.  The only progress I have made is using my finger nail and intensely scratching one spot at a time...but this would take forever.

Is there anything anyone can suggest that I can use to clean this film off of them mask?  I have heard that some oils can damage it and I would like to avoid that.

As far as the type of rubber...I can not say for certain.  There do not seem to be any marks/symbols to signify anything.  The rubber is about 1mm thick.  It is very flexible.  It was made by liquid rubber in a mold.  It seems to be a very high quality rubber and product.

Thanks for any help.

RE: Best way to clean black rubber mask?

Try using armor-all or similar rubber cleaners.  Google the term "rubber bloom" for more info.

RE: Best way to clean black rubber mask?

Try warming the rubber mask. The ingredients in the rubber that bloomed may re-solubilize into the rubber at a warm temperature. I'd initially try maybe 50C-70C (120-160F).
It may not be a permanent solution, tho, as the ingredients may bloom again in the future, but it may take a while.
Good luck!
