I kept my unmixed bottle in the refrigerator and had not problems. Once mixed with distilled water, again I have not had any problems. You may have gotten a bad bottle--contact VPI or your dealer--they should replace the bottle.

VPI cleaning fluid and fungus
Does anyone know what the VPI cleaning fluid is made out of? I have a bottle that has been sitting for a few months, unused. I looked at it today and in the bottom there is a 2"X1" fuzzy grey-green ball that looks suspiciously like a huge ball of mold. Now, that can't be good for my vinyl. Granted, all of the fluid should be vacuumed off, but this still concerns me. Is this just a bad batch of cleaning fluid? Should I switch brands?
