Hey Guys, found something today to clean Needles for your paint guns that won't scratch or bend your needles. I'm in Canada so bare with me on this. We have a product up here called a magic eraser made by "Mr.Clean" it's a cleaning sponge infused with cleaning agents. It's quite soft and light, you can poke the needle with ease through it and run it back and forth. It's quite remarkable how well it works! Hope this might help. Take care, and Paint On!
