Metal Mold Refinishing

Hi Steve,We make and sell vriety of moulds (
www.ipfco.com ), but I have never had opportunity to work with a metal chocolate mould.I had a look at the picture, and based on my experience of making metal tooling for our moulds, I would say as follows:1. Most important - don't do any thing, till you are sure of what to do.2. From the picture, it is difficult to know the metal of it. It can be aluminium, or tin plate. I know of some aluminium moulds with are made with Cast aluminium, but your mould does not look like them. It looks more a sheet metal.3. The close up pictures are a bit blurred, but it seems, that inside of the mould, is in a much better condition, but out side surface does have blemishes. Inside blemishes, what ever they are, look very small.4. What should I tell to you do??a) If possible, show the mould to some hardware person, or an metal engineer to be sure, what metal it is.b) Depending upon, metal, you get rust removing sprays, that you spray on effected surface, leave it for some time, and then scrub clean. A caution - after cleaning the surface may look dull, and may need shining, so, after removing rust, you will need to use a suitable polishing agent, and your hands to get back shine. Your neighbourhood hard ware store could give you necessary advise on this.c) a very unlikely, but possible chance - what you think rust, is actually chocolate deposit. So, have a very close look. Use warm cloth or warm soapy water to rub it off, if it does. If it is stuck badly, use a wooden stick, like tooth pic, to scrap it out.Just check on these, and if you think OK, please get back here with what ever results. Would love to know, what happened.All the best.Arun.
