What is the secret cleaner

Great question! I'd love to know the answer to this too if any has any input.

Tilex

Tiles works, but Clorox Cleanup works better.

I've found simple green works. Might need a little scrubbing with a brush, but it gets the staining off.

Best solution I have found is dial up wash co when in an RV park about twice a year. They wash & wax and it looks good.

LA's Awesome Cleaner - usually available at The 99 Cent Store, Dollar General, Family Discount, etc

Awesome is a really good cleaner but don't let it run down the side of your rig, tape paper towels or work towels underneath whatever you are cleaning. It etches your finish. I use it diluted.

Mr. Clean Magic Eraser.

I have used this and it works really well even on the vinyl trim insert. Jomax I think you can find it at Home Depot or a similar big box!

Purple Power, diluted. Also an excellent black streak remover and cleans the mold off awnings and toppers. It will remove any wax and protectants applied previously too, and why it's a great prep before the big chore. Rinse thoroughly after using too!

P.S., Have vinyl fence or gutters stained from roof run-off? You'll love Purple Power as it'll clean them beautifully! Sold at your local Walmart, auto parts store, and Amazon.
