For very dirty records I use warm water with dishsoap and a very soft towel to dry them. A sponge works fine to clean the records. Towels are used to lay the record down to soak off the water. Cheap; recommended as the method by Last Record as well as Nick Gowan.
Once the gunk is cleaned off I just use the Last Record fluid with their applicator device as I posted earlier.
