These wipes are crazy good! I really wasnt expecting much when I started to clean my oily cassette (I used Synergetic). I rolled up the wipe into a strip, rough side facing out, and started to 'floss' the cassette. With just one floss, I could already see my cassette's original silver. Within 3 min, the whole cassette was clean enough.
Very easy to clean the oil and grease very easily from my bead-blasted Ti frame.
I've never been this impressed with a cleaning product. Even a dedicated foam spray drivetrain degreaser with a toothbrush isn't this easy.
One thing I dislike is the smell. It has this nauseating citrus-y smell that lingers from the cannister.
