Contact Mike Konrad at Aqueous Technologies. He posts here often. So his contact information should be in the searchable archives.

These chemistries (Zestron, Kyzen & Envirosense) mix with water and require a DI water rinse after. I do not know of any non-aqueous cleaning chemistries that are enviromentaly safe.

Pete, I think you mean these are all companies that supply chemistries that CONTAIN VOCs. Zestron, Kyzen and Envirosense all make cleaning chemistries containing VOCs.

They have some with VOC content and others without, or very very low content that it will pass NJ and CA emmissions, which are the toughest in the USA.
