ThanksMy last purchase was a quart of the concentrate from Amazon for under $20. Maybe they're out of quarts? I agree that a gallon would be ridiculous for this application, the stuff is super concentrated.
Any lab or chemical supply store should have it, though the ones in my neighborhood tend to sell at 20% over list price.
I found this tergitol record cleaner online recently called Tergikleen that may interest others
Tergikleen will work with all cleaning machines no matter how simple or expensive. RINSING off the cleaner, is a MUST, this is not a one step cleaner. TERGIKLEEN ™. is a proprietary blended Tergitol® formula that attacks oils, waxes, dirt.
