Someone on the 90s section asked if Valvoline/Pyroil brake cleaner is non chlorinated.
Their website seems to show two types:

Here's one listing:
Brake Cleaner/Degreaser No VOC 15 Oz
PYROIL NVOC15 Brake Cleaner/Degreaser Non Chlorinated No VOC Container Size 15 Oz. Clear Can Transparent Boiling Point 133 F 0.1 Specific Gravity Dissolves ....

Here's the other one,says it contains chloronated solvents.
