I don't think there is any snake oil that will work for any period of time. Try your salts, battery acid and report back.
I purchase a batteryminder charger about 6 months ago, $110. It is suppose to desuflate batteries, however the manufactor says it may take up to 2 months do get the job done. I could have bought 2 excide batteries from Rural King and have change left over. I'm not totally impressed with the battery-minder charger.
About a month ago, a person gave me a heavy duty battery he used as in his boat as trolling battery. I added 1/2 gallon of distilled water to battery. One cell had the top part of plates exposed to the air. 3 of the cells took a charge right away. The other 3 were flat. A month later 2 of the dead cells are back and the one with the exposed plates is only 25%.
Here are the simple facts. Discharge a battery and you produce hydrogen, oxygen and Sulfates on the plates. Some of the hydrogen and oxygen excape as a gas and some remain as water. This is why you have to add water.
Charging the battery reverses the process combining water and sulfates making H2SO4, battery acid. If you have sulfates remaining on the plates, your battery will never take a full charge, it needs to be desulfated. There are many opinions on the best way to do this.
Some claim their snake oil works best, however how many of those claims are backed up with load tests. You can take any battery to places like NAPA or Auto Zone and they will load test the battery for free.
Again, try the snake oils, fast charging, slow charging, then take battery to NAPA and Please report back on what they tell you. This isn't the first time your question has been asked, and it mostlikely won't be the last.

Today's Featured Article - Third Brush Generators - by Chris Pratt. While I love straightening sheet metal, cleaning, and painting old tractors, I use every excuse to avoid working on the on the electrics. I find the whole process sheer mystery. I have picked up and attempted to read every auto and farm electrics book with no improvement in the situation. They all seem to start with a chapter entitled "Theory of Electricity". After a few paragraphs I usually close the book and go back to banging out dents. A good friend and I were recently discussing our tractor electrical systems when he stated "I figure it all comes back to applying Ohms Law". At this point
