Is it empirically or quantifiably "much better"? All we know is that it's "much more expensive".
Better can be subjective at times.
Perhaps a breakdown of their ingredients may
be helpful in determining "better"? Here goes:
Both D120 and this Aquapel Glass Cleaner contain:
•2-Butoxyethanol...surfactant
•An "alcohol"...a type of solvent
•Water...carrier/universal-solvent
Their main differences are:
•Their "types of alcohols"
•Their delivery systems
Let's begin with the "alcohols:
•D120's is Isopropyl Alcohol...IPA
•Aquapel's is Ethanol Alcohol...
-also used in products like: antifreeze mixtures
Note: Not something I'd ever use on any of
my vehicles' dashes...but to each their own:
TO WIT:
Aquapel is thick and foamy.
It also seems to work well for a quick dash clean-up.
Next...Their Delivery Systems:
•D120 mostly by liquid spraying vessels
•Aquapel by propellant: propane/butane
AFAIC:
I would not use the product containing
Ethanol...but for anyone else: The decision
of which is better, can, once again, continue...
if so desired.
