I got my first Bottles about three weeks ago, and I am very impressed. I have used Renovex (expensive, instant headache and the 1,1,1 trichloroethylene is cancer-causing) and other products and this is the best I have used. The gallon of Renovex has been sitting in the cabinet for three years, it wasn't worth the loss of brain cells. While I don't claim any special knowledge, I have worked in 30 theatres, 10 plexes, and own three setups of my own.

Is 1,1,1 still legal in the US? It was banned by the European Union in (I think) 1996. This caused lots of problems at the time, because ultrasonic film cleaning machines that relied on it suddenly became useless. Several archivist friends of mine spent most of the mid-90s trying to build up stockpiles.

But, Neil you are forgetting the great high you get from Renovex. Send it up my way. I know some people that will buy it for that.

Are 1,1,1 and Xecote the same thing? I seem to recall that Xecote was banned in the US around 1996 or so.

1,1,1, is a carrier and solvent that will dissolve really nasty complex molecules and hold them in solution until you breathe them in.I think they used it in the old Xecote.
Bids will be accepted for my legacy gallon of Renovex-remember, since it is illegal, it can only be used for recreational purposes only...

Russ, Just so you know, that is not a third leg. That is what makes him your son.
BTW quite impressive.

Leo, Percloroethylene is the replacement for tri. It is used in all systems that tri was.Like all chemicals used in the film industry care must used in the handling of Prec. Its drying time is a tad slower but I have not heard of any problems with it's use in cleaning machines, by the way, one of its other names is Piclear the fluid used in wet gate projectors. Tri is banned in Aust also.

Many film cleaning solvents and film treatments contained 1,1,1-trichloroethane (methyl chloroform) as the primary solvent. This solvent is no longer manufactured because it is believed to harm the earth's ozone layer ("Montreal Protocol"). Existing supplies may be used or recycled, so you may still use the original XeCote or Renovex cleaners with proper precautions. They are considered hazardous waste, so DON'T just throw them in the trash or dump them down the drain!Perchloroethylene (tetrachloroethylene) has long been used as a "wet printing" solvent, because its refractive index is suitable for filling in film scratches. It is not classed as an ozone depleter, so it is still used by film labs and the dry cleaning industry. It is much more hazardous to health than methyl chloroform, evaporates more slowly, and is less effective as a film cleaner. But it is sometimes used for film cleaning, replacing methyl chloroform.
Contact the manufacturer of any film cleaner or film treatment to obtain the Material Safety Data Sheet (MSDS) for the product, which gives details on the hazards and proper handling and disposal procedures.
