THE ACTUAL OILS & CLEANERS
The Material Safety Data Sheets I got from them are for the actual oils, cleaners, and rim grease (only no-toil sent an MSDS for rim grease). The MSDS, as you are probably aware, break the component into it's basic ingredients, safety precautions, spill and clean-up, flammability and fire fighting methods, first-aid for the user and doctors, etc. I was curious about these products because even though they work great and are touted highly the manufacturer is still only in it for the money. I too want to wash my filters in the sink but some of the chemicals are in question (to me) as harmful. I think the No-Toil looks the best. Also, I plan to procure my own cleaner since it's readily available and cheap at supermarkets (the MSDS tells you what it is by the CAS #). Just neat stuff to me. I hate using kerosene and then soapy water too, it's just too messy!
