I finished this table at the end of August, and it’s already got mildew stains on the top—we’ve had an awful lot of rain here the last couple of months. It is made of cypress and was stained with Cabot outdoor deck stain (Jarah brown). Is there anything I can do about the mildew? The treated pine adirondack chairs I built this summer with the same stain is clear as a bell.

I think it’s probably from the wood it self. I’ll be interested to see wath the gurus have to say too.

That’s unfortunate. Does cabot claim to have mildew resistance? Linseed oil products tend to have a problem like that as I recall and require mildew inhibitors. Behr had problems with their exterior siding and deck stains similarly.

I’ll have to check the can to see if it says anything about mildew.

Do you think I could sand it off with 200 grit and apply more stain?

I’m with Rob 50/50 household bleach and water in a test area.

I imagine you’ll have to go through the whole cleaner, brightener, mildewcide schtick. Clorox might help but may take several treatments.

The only thing I found that would actually kill mildew and at least lessen the stain was Tilex. I tried bleach first and it didn’t seem to do anything but maybe you’ll have more luck with it if you try it.

Just an update: I went to Lowe’s and bought some stuff called DampRid Mildew Stain Remover Plus Blocker, which contains no bleach or acids. It worked beautifully. After spraying and sitting for five minutes, the mildew just wiped right off with a sponge. The table looks good as new. The back says that occasional spraying will build up a protective barrier against mildew that isn’t diminished by weather exposure. We’ll see, but so far I recommend it.
