You know it should be disposed of properly, but when you fill out REM's Hazardous Material Pickup Request, you have no information about the chemical composition.
Unknown chemicals are a problem for several reasons.

Periodically inspect all chemical containers for missing or damaged labels, immediately replacing or supplementing hard to read labels with essential information. Label commercial products not only with their names, but also the manufacturer's name and address.
