I use some sort of boat
wash. When researching, I didn't see much of a difference between brands. Have been lightly washing
about once a week. Not that helpful, sorry.
As for the wax, you want/need something that will protect while not being slippery on the non-skid. I have been using Marine
31 spray wax for non-skid. It does as a bit of shine (and hopefully protection) without making it slippery. Have noticed that it cleans up much easier, so that's cool. Think spills in the cockpit
Have only done one application of Marine
31, so no long term details. Will try to redo once every 6 months here in the Caribbean
. At $30 a bottle and my 38' sailboat needing two to three bottles, it isn't cheap
Hopefully I'll be able to report back with more details one day...
