Audiodesk pro with only water

I don't understand.  This thing is 3 or 4 grand if I am googling on the right unit.  And you don't want to spend $25 for the correct cleaning fluid?  There are some forums with discussions of failures, and the cost to return to Germany to repair plus the cost of parts, and they are not cheap.  If it were me, I would wait and get the right fluid and hope the reliability of your unit is good.

I don't own one of the cleaning machines and I certainly don't know what materials are put into the fluids that are sold to be used with them. I suspect that it is a "brew" of a few liquids. One comment I do have is the use of some sort of surfactant (meant to lower the surface tension of a liquid). This helps the cleaning since residue is less likely to "cling" to a finished/dry record. Those "brews" most likely contain some type of surfactant?

I don't think Windex is a typical surfactant and probably contains a small amount of ammonia and some other stuff. Do a search for generic surfactants. One that comes to mind is Photoflo made by Kodak. Meant to prevent drying spots on films processed in a manual manner. Probably found online or at just about any photographic supply dealer. Cheap and a 2 oz bottle would probably last a lifetime since one cap full will treat over 5 gallons of water (distilled).Good luck to you.

I use just water most of the time. On new or precleaned vinyl it works great. Been doing this for years. 
I wouldn't use any other cleaning solution but the Audiodesk cleaner.

I use the Klaudio US machine, which the manufacturer says should be used only with distilled water. It works great, and removes the contamination from any LP except the rare, badly abused used record. For them, I use a Nitty Gritty machine to preclean. But that’s unusual.

Thank you for the input guys.
 Tom I think I agree, I will be using just water on my new or already cleaned records on my VPI & use the solution when im ready to clean a bunch of used records. 
At $1.25 for distilled water , I can change it every 20-25 records. 
I am tempted to add a couple of drops of Photoflo  to the water but not sure if that will void the warranty or damage anything. I am not sure what they put in it.
 Bailyhill -at $25 a pop for the cleaning solution , if im only able to clean 40-50 records in 30 days then I have to empty the cleaner according to AD so it does get rather pricy.
