Great stuff, time saver

Works as advertised. Like the color indication of acids as I wasn’t entirely sure what was what when I doused this stuff on. It became clear quickly though as some portions lit up pink and others did not. Seems to be reasonably priced in my opinion too. Sure beats getting out a cup on water and making soda and scrubbing about like I had been doing for years before finding this stuff.
