/6 Idling Problems

My gosh, thank heavens for exhaust hoods.

Cresylic acid used to be a common component in carb cleaners as well.

Thanks for the refresher on chemical dangers. I had almost forgotten them from when I used to sell specialty and industrial chemicals to car products formulators.

One nasty but fairly common one that is far more dangerous than carbon tet or methylene chloride is HF, or hydroflouric acid. This is sometimes found in automotive aluminum brightners The flouride ions migrate rapidly through unprotected skin and can cause rapid death. Users are cautioned to have topical antidotes immediately available.
