Hi All, new member here. I'm working on a project and I've replaced our doors and selected new knobs of the brushed nickel look. I'd like to reuse the existing hinges. They were covered in paint, so I boiled them and got the paint off. What was revealed is shown in my photo. Looks like some sort of brassy stain or finish thats damaged. Underneath are silver hinges that would match my knobs fairly well if the stain was removed. Can I remove the stain? Should I be worried about rust, etc. if I do? Thanks for any ideas.

For many years, Playtex-type gloves have "melted" in my house, without their being in contact with any corrosive materials--just while lying around on surfaces. Giant holes appear and fingers stick together, and generally the plastic looks like it has been melted, though of course it never gets warmer in the rooms than the low eighties, and a pair even melted in the basement where the temp never exceeds 70 degrees F. It's quite amazing. Over time, at least thirty pairs have become unusable in this way. A quick Google search found someone else with this issue but it doesn't appear to be common, and those responding to that person apparently had never observed it in their own lives. But now I have what may be a related, and very expensive, problem. I have a manual blood-pressure measuring device (officially called a sphygmomanometer) that I must use daily, and it's made, in part, of some rubbery-type plastic tubing which is all one piece with a bladder of the same material (so the tubing can't be replaced). Well, this vital tubing has become cracked--very badly cracked--over time, to the point that it's becoming difficult to pump up the pressure to the required value due to the leaking of air from the tubes before it gets to the bladder in the inflatable cuff. This exact deterioration has occurred several times in the past, requiring me to replace the unit, at considerable cost. So, my three questions are: 1)Are the glove and blood pressure device deteriorations related? 2)What is causing this to happen? 3)Most important, what can be done to prevent it? I wasn't sure if this forum was the proper one for this question. If not, I apologize.
