exterior shell protection

[rbhtrail]

Hello All, Does anyone know of a safe tree tannin stain to use on the shells of the TM . Or a protectant for the exterior shells.
Thanks in advance for any help or suggestions.

The only thing I've found that actually works is soft scrub. However if you get over eager it will dull the finish. There are a number of products which claim to work, just google RV and tannin streaks.

Thanks for the soft scrub and overeager results. I tried fantastic on a small area and had little benefit. I'll continue the journey,test solutions in small areas and report what works.
Thanks again
