I bought a gallon jug of Zep industrial degreaser for twelve bucks. You water it way down making it incredibly inexpensive and it works better than anything else I've ever used. My question is might it be too strong? The first time I used it I didn't wear gloves ( I realize how stupid that was). I lost a layer or two of skin and couldn't feel my fingertips for a week. I tested it on an old chain and without oil it rusted over night. As long as I get everything lubed up it doesn't seem to damage anything but I wonder if it could weaken the metal. Any ideas?
