Hi everyone, our 2021 Montanna that is located on the Ocean's West coast has developed algae or mildew from the very wet Winter we had. Was told to use Jomax Housecleaner & Mildew Killer, made by Zinsser, I want to make sure it will not harm the exterior finish. Called keystone, weren't much help. Tried Zinsser Corp. Waiting for a reply. Its made for house siding, but is it safe for our trailer?
It was supposed to the have a coating applied at the time of purchase to help preserve the finish, Can't remember the name, Paid extra for it at Camping World. Went back the next day and they said they applied it. The Rig still had the coating of dust on it that it had when we purchased it. Told Keystone about it. They didn't seem to care.
We would appreciate any advice.
