Best price: 5.10 (Motobitz)
For: Relatively cheap, streak- and smear-free
Against:For glass only, limited effectiveness
We got a streak- and smear-free finish, but the Comma Cleaner didnt have the power to cut through insect remains without some time and effort. Good results, eventually, but recommended for glass only.
Good value, and the second-cheapest liquid on test, volume for volume, but not widely available.
Ease of Use:
Straightforward to use, leaving no mess or residue.
Only recommended on glass and is therefore less flexible than most of the other products on test.
