A bowler I know from another state had a mix of 50-50 Simple Green-Alcohol in a spray bottle for cleaning his bowling balls. He said he had the bottle in his ball bag and hadn't used it for quite some time. When he went to use it the other day, the bottle was empty and rattled. He took the lid off, turned it upside down and a few clear crystals and no liquid came out of it.
Does anyone have any idea what caused this?
