Cleaning fluid on the cheep

A short time ago I was fortunate to have a family friend decide to get rid of their old vinyl records and hand them over to me. About 250 albums is my estimation. As you might guess, they were not taken care of real great. All are in their sleeves and jackets but have been in storage for years.

I do have a VPI 16.5 cleaning machine but do not have much cleaning fluid. Unfortunately I have hit some financial hard times as of late and cleaning fluid is not cheep.

I was wondering if there was a good substitute for the normal cleaning fluid bought at retailers that I can use in it's place? Maybe using product from the grocery stores? Like distilled water and a mild cleaner?

Or any other suggestions?

Any ideas would be much appreciated!
