I think you really need a hose rather than a towel. It has to be flushed away. Is the better looking side the one done while the towel was cleaner?
I dab more on about ever 10 minutes to make sure it doesn't dry and keep this up for the full half hour recommended. It's very fast - beer
in one hand, foam brush in the other. Three laps of the deck
I would try again and use a hose - or even buckets of water
sluiced over the metal. I'm not sure salt water
is ideal but it's certainly better than a towel. When done correctly there is no polishing needed after use. The stainless looks like you just brought it from the store.
