Author Topic: Alcohol Gordon McLeod Film God Posts: 9532 From: Toronto Ontario Canada Registered: Jun 99 posted 12-14-2003 04:55 PM                     The bottom line is the man (or women) who signs the paycheck says the company policy is do it this way then that is what one had better do unless it is dangerous to yourself or others or is illegal  |  IP: Logged Leo Enticknap Film God Posts: 7474 From: Loma Linda, CA Registered: Jul 2000 posted 12-15-2003 01:45 AM                        Slightly off-topic but please indulge me... About 10 years ago an usher at a cinema where I was working told me that her cassette deck was sounding 'fuzzy and a bit muffled' and wondered if I could help. After establishing that she wasn't just playing a suspect tape I suggested that she cleaned the heads with some cotton buds and a bit of IPA (by which I meant isopropyl alcohol). She sounded very surprised: was I sure that this was the right stuff to use? Yes, I assured her, use it very sparingly and it'll clean your heads a treat. She came back the next day saying that she'd done it, that it hadn't made much difference, '...and so I drunk the rest.' 'You did what?', I replied. It turned out that by 'IPA', she thought I'd meant India Pale Ale... and had spent the previous evening trying to clean her tape deck heads with beer!  |  IP: Logged Michael Schaffer "Where is the Boardwalk Hotel?"

Everyone knows you don`t clean the heads with India Pale Ale...you use Watney`s Red Barrel.  |  IP: Logged Christopher Seo Jedi Master Film Handler Posts: 530 From: Los Angeles, CA Registered: Jun 99 posted 12-15-2003 12:00 PM                     David, Getting back to your original question, I have used isopropyl alcohol to clean various plastic and metal rollers including Christie, Kelmar, etc. rollers, without a problem. I'm not quite sure how alcohol could dry out plastic rollers that are not exactly moist to begin with. I would use only 99% isopropyl alcohol and not the watered-down stuff as water can always be a problem around metal parts and film. I suppose I like alcohol for cleaning for two reasons: (1) it evaporates quickly, (2) it is a single chemical. I suppose reason #2 is a bit arbitrary. But as Gordon said, as an employee you must follow the rules of whoever sets policy.  |  IP: Logged Chris Hipp Phenomenal Film Handler Posts: 1462 From: Mesquite, Tx (east of Dallas) Registered: Jul 2003 posted 12-15-2003 12:11 PM                     While I do not recommend that David do anything that his boss would not approve of, there is nothing wrong with learning the right way of doing something. Perhaps you can persuade your boss to do things the correct way.  |  IP: Logged Josh Jones Redhat Posts: 1207 From: Plano, TX Registered: Apr 2000 posted 12-15-2003 12:26 PM                        As usual, I joined this topic too late. When cleaning rubber items such as pinch rollers and pucks, clean with alcohol and wipe it off very quickly. If you allow the alcohol to sit on the rubber too long, or allow it to evaporate, the rubber will eventually harden. I use it on cart machine pinch rollers all the time.

Much better to drink India Pale Ale. Drinking Isopropyl Alcohol could put you in the hospital.  |  IP: Logged Paul G.

The oilite bushings were cleaned by the same thing, and never oiled. Never had a failure related to the use of isopropyl alcohol. Never had a failure of a bushing, either.  |  IP: Logged John Wilson Film God Posts: 5438 From: Sydney, Australia.

FYI. Since I've started coating the trap with Film Guard, my old E-7s run quieter.  |  IP: Logged Will Kutler Phenomenal Film Handler Posts: 1506 From: Tucson, AZ, USA Registered: Feb 2001 posted 12-16-2003 11:35 PM                     Alcohol on the bare aluminum platter decks is a MAJOR NO-NO! Notice how the alcohol reacts with the aluminum and leaves a black residue? As per the AW-3 service manual, the decks should be cleaned with a light soap and water solution. Use a few clean towels, for washing and drying. And don't flood the decks with soap and water. Wet and ring the towel. And be gentle on the decks, no nead to "muscle scrub". If you clean the decks once a week on a schedule, as well as before each build-up, you'd be suprised how nice, clean and shiny those decks will be! Use a clear, silicon based bicycle chain lube to lube the AW-3 rollers as necessary. Alcohol will dry out and crack plastic. But I believe the AW-3 rollers are nylon, so alcohol should not be a problem there (at least I never had one). As for rubber rollers, you'll definately know if alcohol is drying them out! The rubber will start to disintegrate, and will leave a nasty residue and chunks all over the place.  |  IP: Logged David Whitbeck Film Handler Posts: 70 From: Tempe, AZ Registered: Jun 2001 posted 12-24-2003 12:31 AM                     Thanks a lot guys. As for the "do as you're told" statement, well, I'm not very good at that... Anyhow. I have noticed the pad rollers in the projector seem to be coming apart on some machines... Which is funny because they told me no on the platters but go on the projector. Almost feels like they have it backwards.  |  IP: Logged
