after a failed attempt at rum cake, my copper mold pan has this sticky/hard stuff on it. It’s on the silver-colored inside, not sure what metal it is. Of course I can’t put this in the dishwasher, so I haven’t done that. I have tried to hand wash it, soak it and scrub, soak it and scrap with plastic spatula. All have gotten very little off. I’ve been able to scrap a little off with my nails, but the little I’ve scraped off, leaves a residue that can’t be removed. Don’t really know what it is that is stuck on it. It’s is residue from the dough I used. Any suggestions? I can’t use it again until I can clean it. Thanks for your help.

Try soaking it in HOT water overnight..that is if it is sugar based.

You could cut a lemon in half. Sprinkle some salt on the lemon. Now rub the lemon on the pan. It worked for me. It did take a lot of work.

Hope it helped.

(PhysOrg.com) — Scientists are envious of nature because of its ability to build up highly complex structures like organs and tissues in an ordered fashion without any problem; it takes a great deal of effort for scientists to produce defined microscale structures.

How the grinder AND the separation of the plastics and copper is done? Vacuum and/or vibration? I’m looking for pics or a video that shows the “Inside” of the machine. I find videos of the machines doing the process but that really does not show me or tell me how they work. I’m thinking about trying to fab. one. ….or has anyone build a “homemade wire stripper? If you have or in the process can show you what I did last winter. Maybe we can help each other in design?
Problem with going to local scrap yard is they may not have a chopper for wires. their chopper is probally for cars, etc.,
as for everythingchanges: how does a chopper work, not a stripper

This material has been increasing in price from year to year and is certainly one of the best ways you could earn some extra cash. Price of copper scrap has been increasing tremendously as gold has and is now one of the most sought after metals in the world today. Due to this fact, theft of copper scrap has been on the rise lately as electrical cables, engine parts and railway tracks have all been stolen by irresponsible individuals. However, if you’re planning to do recycling of copper legally below are some methods you could do it successfully.

First of all start by collecting and saving the copper sources that you find available around you. Power cords, electrical appliances and also pipelines are some example of items you could get copper out of. Hence, if you have these kinds of items available around the household that you don’t need, collect them in a particular place to sell. Besides that, you could also head down to local garage sales or also pick up items from trash to sell off at local recycling companies.

Next, what you should do once you’ve collected the scrap copper would be to strip away plastic wires or coating that you can find on it. In case of wires, you just have to use a knife and strip the coating out of the wires. Recycling companies do tend to pay a bit more if the coatings are removed.

There are various types of copper available and one should know on how to separate them before actually selling it off. The best type of copper metal would be the ones that are shiny and look new whereas the old, worn down types should be the last group you should sort out. The best looking scrap would be the ones that would earn you the highest income.

Lastly before selling, always research the latest price of copper scrap. You could do this through the internet and also getting the information from the local recycling companies.

At the end, I’d like to share cool website with more information on topics like scrap copper prices and copper scrap prices. Visit for more details.

This time i am thinking of stripping the cables so i have pure copper wire, but im not sure if its worth it. Obviously its going to take a long time, and i dont mind that, but i dont know if i would actually get any more money after i lose the weight of the plastics.

So do you think the weight of the cable will be 10% copper wire, or 70% wire, or what?

thanks for your answers :-)
