What do you think about this product as a bio-degradable cleaner?
I sold a lot of it when I had a job in a paint store, as a surface prep for painting. I dont recall any product warning stating not to use it on metal. It is a great cleaner but I would sure test it first. I've had nothing but trouble with Simple Green and metal finishes.
ah, found the MSDS. https://www.krudkutter.com/index.php?option=com_content&view=article&id=54&Itemid=53
it contains over 91% water, and anywhere from 1 to 3% of the following - an unknown trisodium salt (i'm guessing trisodium phosphate, or TSP), an ethoxylated alcohol (soap or detergent), and sodium metasilicate (which breaks down to sodium hydroxide). it's basically a combination of water, TSP, soap and oven cleaner. it will likely damage plastic and metal surfaces given a prolonged exposure, but will do a decent job of cutting through grease with a little scrubbing. i would just not let it soak.
