Desulfation is legitimate. It can be accomplished by chemical means or electronically by imposing a high frequency current over a normal charging current.
Both chemical desulfation with EDTA and the electronic method with a home made desulfator have worked for me. I presently use a Vector 1095A charger which has both desulfation and equalization cycles. So far so good. A full charge, then a desulfation, then an equalization shows a significant improvement as measured by a Midtronics conductance tester.
Home Power Magazine has had some good articles on EDTA.

I have used epson salt with a couple of good results, it will get the charge started on a completly dead battery and saved a couple. worth a try i put about a teaspon in each cell.
