I have never heard of those products, so I have never used "But" this is what I have done last 4 years.
First year was really a pain as the MH sat under a Maple tree for almost 6 years and showed the results of doing so.(previous owner)6 (before I bought her) It was pretty Blk from the sap's from the tree.
First I used a product called,
1. Mold Armor E-Z House Wash, connects to the end of your garden hose.Spray on wait a few minutes and
Pressure washed it off and the Blk mold with it. Bought @ (HomDepot)
I think around 25 bucks
2. Meguiar's Mirror Glaze #83 Dual Action Professional Dual Action Cleaner/polisher, (I have a really bad back and Arthritis in right hand (managed with Pain Meds) This part took a week. Even with a professional buffer 30 foot MH
3.PPU (Perfection Products Un-LTD) "The Perfect Wax" Euro-Class Cream Wax 32 oz was $29.00.

For a quick detailer I used a product from Wizards Called Mist-n-Shine,
Anti-Static,Anti-Streak,No Silicone,No Oily Film,Slippery, High Gloss,
I found product from NAPA and is usually kept behind the counter. I don't know why and neither did the kid working the counter.
It also removes those Dang BLACK STREAKS...
I have done this 3 times a year with the exception of step 1 & 2
