Don't use alcohol on vinyl; it will tend to leach out the plasticizers in the vinyl over the long run. Probably it's no more risk than using hydrocarbon oils on condoms, but I don't want to find out. If you want a good record cleaning solution, go to your local photo dealer and get a bottle of Kodak's Photo-Flo 2000, which is a wetting agent. Six capfuls to a gallon of water make an excellent cleaning solution. --scott

The cost of a few albums lost pales in comparison of the potential cost of a failed condom ... one must assume you meant strictly the statistical risk of damage vs failure. I had no idea that this problem with alcohol-based cleaners existed (and I'm new to this group, so I don't know if the subject has been beaten to death yet.) Does this mean I should chuck out my bottles of LAST? (It's old, but it still works in reducing surface noise and static.) Kim

I've used a mixture of 80% HPLC grade water (ie. very good double distilled- deionized water) and 20% isopropanol (of similar purity) with a few drops of Photo-Flo/gallon thrown in to improve wetability for years now. I haven't noticed any ill effects on any records (though they don't get washed often, once for 20-30 plays which essentially means once for most of them). I'd always assumed the alcohol helped dissolve oils and organics (mold release compound on new records?). I'd be very interested to hear more on this. Steve Graber work: (804) 924-9976 UVa Dept.

I am confused now. I don't have my bottle of last with me, but I could have sworn it isn't alchohol based. I thought it was like some hydrocarbon solution, like trichlorotriflouromethane or something. It is "thinner" than alchohol, evaporates more quickly, smells different...

However, it's not a cleaning solution either. It is a product intended to be used after a thorough cleaning to somehow "harden" the vinyl thereby extending the record life. Don McDaniel

There are two Last cleaner, regular and super-strength, No contents are given, but to my gold nose it is freon-based.

There's no such thing as trichlorotrifluoromethane, BTW, since you can't stick 6 halogens on a carbon. More likely would be C-Cl2-F2 (dichloro- difluoromethane), a.k.a. Freon, or C-Cl4 (carbon tetrachloride), a.k.a. dry cleaning fluid. You really don't want to be breathing this stuff. Jeff
