The founder of Xerion is my ex-father-in-law and I'm VERY familiar with the product. The technique is totally different than traditional bonnet or pad cleaning. The name means "dry" in Latin, that's why he picked it.
It's great for what it's for...large commercial maintenance. it is also great for commercial upholstery. very high production rates, extremely low cost per s/f (the juice is expensive, but you use very little), excellent appearance improvement, no wicking or resoil.
It requires very specific equipment and technique, without even one of these pieces of equipment it's useless.
-300 rpm rotary, no a 175 will NOT work
-DRY, thin, synthetic bonnets
-fine mist sprayer (pepsi sprayer with a fine cone tip worked well)
-The key is knowing how to use it, it's not hard, but it's different than rotary or pad.
I often used the Xerion product as an emulsifier, or in the early days I would mix it with Formula 90 for a pre-spray that kicked butt. Of course it was not meant as a HWE chem, but it served the purpose well.
One plus, it was odorless, non-allergenic and non-toxic...and it dried completely within 10 minutes, often less with a huge appearance improvement. Retail facilities loved it.
Areas it did not do well in: Heavy grease, heavy soil loaded carpets, cut pile.
Great for maintenance of large commercial and retail though. I would use it again in a heartbeat in the right application. I carried it on my truck alongside the TM. More tools means better choices for each situation.
Take care,
