Manufacturers such as Hammond and Tripp-Lite make good industrial quality power strips, but you won't find them at your local orange or blue big box store. Folks who shop there wouldn't pay what they cost - typically $50-75 for a 4 or 6 receptacle strip. (Medical grade strips go for double that and more, but I'm not sure they're really worth the extra cost.) What you WILL find there is mostly junk. The manufacturers, some of them big names, use the absolute cheapest components available and have them slapped together in China or Vietnam. The one you have probably has 3 duplex receptacles similar to (or even cheaper than) the ones you can get in the 50-cents-each boxes on the same store's bottom shelf. The receptacles installed in new homes, even very expensive ones, aren't much better. If the builder can save 10 cents on each one, that can easily add up to many thousands of dollars per year in additional profit. All they have to do is last for the term of the home warranty. These receptacles don't make very good contact to begin with. It gets worse over the years as they get less springy and corrode. As the contact resistance increases, heat builds up, making things worse. I've had 15-20 year old builder-grade switches and receptacles fall apart in my hands when I took them out of the wall. The plastic just cracked apart, probably because it got hot and degraded. There's no point in trying to salvage that junk. If you're going to pull out a recept to clean up the wire and put it under the terminal screw, don't even put it back into the box. Replace it and the others with better new ones. With a little careful shopping, you can get industrial- or hospital- grade receptacles for 6 or 7 bucks each, sometimes less. It shouldn't take more than a half-hour to change the first recept, and less than that for succeeding ones. You can tell the better recepts because it takes markedly more force to insert the plug. They have better quality spring brass contacts so they'll carry on gripping plugs solidly for much longer. You can plug and unplug your EV thousands of times and still have good, low-resistance contact.
