Tried to clean the drive unit on my boat and nothing worked even with scrubing. Sprayed this one and wiped off. Lower unit looks like new !

I used this on my 2016 Alumacraft 165 Classic in my driveway on a cloudy day. I sprayed about a third of a side at a time. Let it set 3 minutes, then brushed with a soft brush and washed it off. Used on aluminum hull, paint, decals, everywhere. No damage to anything, the hull is super clean. I used about a half bottle on my boat. Took my about an hour. Great product. I will never us anything else.
