I still have a big red jug of the Discwasher stuff, but I've also used a 7/8 DI water, 1/8 IPA mixture too. Some people say you have to be careful about using a mixture with too much IPA in it, because it can dry out the binders and stuff in the vinyl. FWIW.

Oh, I heard once that the trick with playing records wet, is if you do it once for a particular lp, you have to in the future as well, or else it gets really poppy and clicky... I'd be too afraid of getting water into my turntable to do this.
