Vinyl cleaning comes up a lot so I thought I'd share my experience with Malco. It gets rave reviews on WW and I had tried everything else so I gave it a shot to compare.

The vinyl was already fairly clean, so pictures wouldn't show the improvement, but it was fairly impressive. Dirt just lifted to the surface. I used a scrub brush since that's my standard procedure, but I doubt I'll bother next time. Even spider poop wiped right off. It's a very aggressive cleaner so you have to keep it away from brightwork, and it dries out the vinyl (and your hands) big time. I followed up with a good water rinse and a 303 application.

In short, there really isn't much that compares. To really test it I tried using Malco on my shop sink. This sink was so badly covered in paint, stain, grease from the bbq smoker, etc that we planned on just buying a new one. I sprayed it down, let set for 1 minute, used a plastic putty knife to scrape it all down, and rinsed. It looks brand new... amazing.

The downsides: not approved by vinyl mfg, no UV protectant, very aggressive, can't stop cleaning once you start.

I plan to use Exquisite and 303 for most of the season and the Malco for the occasional deep cleaning.
