Years ago I used to sell a PF cleaning kit on Ebay. In it you got a bottle of cleaner and a bottle of liquid wax plus a buffing cloth and 2 shiny mirror finish balls. From memory, it was $50.
The buffing cloth was a duster from Crazy Clarkes.. mirror balls I got from AMD QLD when the busty blonde hot chick worked there.. the cleaner and wax was a bulk buy of automotive products that I dispensed into smaller bottles.
It worked a treat and I used it on all my machines  from 50's upwards. Never had an issue.
But back to the product at hand... water less means it has some sort of alcohol base.. be it isopropol or methyl etc. This also in spray form evaporates quickly... very quickly!

Personally, I cant see what damage you can possibly do.
