With all the big multiplexes going up and shutting little guys like me down, It brings me such great joy to announce our own megamultigigaplex going up this year (WITH IMAX YIPPEE SKIPEEE). The advantage is that we own the 26 acres surrounding it so there is NO WAY that we can get built out by competition like we did in Aurora. Yeah and Im santa claus..... Actually I myself am about to embark into a new company that produces live and film entertainment but I swear I will never ever never ever stop playing with film-guard no matter what! ------------------

Many of the proprietary film cleaners and lubricants contained methyl chloroform (1,1,1-trichloroethane) or perhaps Freon as the solvent. These solvents were very effective in cleaning film, dried quickly, were non-flammable, and were relatively safe to use with proper ventilation. Wax or lubricant could easily be dissolved in these solvents for use in lubricating the film.Unfortunately, the use of these chlorinated solvents may harm the ozone layer that protects the earth from ultraviolet radiation. By international agreement ("The Montreal Protocol"), the manufacture of these solvents was discontinued about 5 years ago. However, at the time, existing supplies of the solvent could be continue to be used, although no more would be manufactured. They could also be recycled by distillation. Some film cleaner manufacturers "stocked up" on the solvent before manufacture was discontinued, or are using recycled solvent. But as supplies are depleted, the price has gone up considerably, forcing manufacturers like XeKote and Renovex to reformulate their cleaners. Several alternative solvents are available, but they each have disadvantages to consider. Pure isopropyl alcohol (NOT rubbing alcohol which has water in it) can be used as a film cleaner. It has fairly good cleaning ability and reasonably fast evaporation rate, but is flammable. Tetrachloroethylene or "perc", a solvent widely used for dry-cleaning clothes, can be used, but evaporates slowly, and has significant health risks. Toluene likewise has health risks and is flammable. Hydrofluorocarbons have a very fast evaporation rate, and are quite expensive. To know what solvents are in your film cleaner, and what safety precautions are needed to properly use it, consult the Material Safety Data Sheet (MSDS) supplied by the manufacturer. ------------------
