    LESLIE: Joann in Ohio is on the line and has an issue with how to clean mold from deck. What can we do for you today?

    JOANN: I have two decks in my backyard. One of them seems to be fine but the second one, which has a very large dog pen on it, has developed a lot of mold over the winter. And my thought is to buy a lot of bleach and to dilute it and just scrub the mold off. But perhaps you have something better that you could tell me to do.

    TOM: There’s a much more effective way to clean mold from deck. It’s a product called Spray & Forget. And just as the name implies, you spray it onto the deck surface and you don’t do anything else. You forget about it and it essentially goes to work immediately. And within a few days, it will degrade and destroy the mold, mildew, algae and moss that forms on your deck.

    JOANN: Can I then have it repainted?

    TOM: Sure. Absolutely. Mm-hmm. Yeah. You could paint it after that. But the thing is, if you use a lot of bleach, you end up potentially damaging all the landscaping that’s around that, as well. So, I would definitely recommend Spray & Forget.

    JOANN: Is this – come in a canister or a powder or something?

    TOM: Comes in a bottle. It’s a no-mix bottle.

    JOANN: In a bottle?

    TOM: Yep. You can find it at lots of places. I think The Home Depot has it and many other retailers. Their website is

    JOANN: Very good. I will definitely do that. And it’s safe for pets, too?

    TOM: Yes. It’s biodegradable. It’s a safe, non-corrosive product that works really well to clean mold from deck. It’s also a great roof cleaner. Sometimes you get moss and it discolors your roof shingles. You can spray this on your roof. It does the same thing.

    JOANN: Oh, that’s wonderful. I am going to purchase this. Thank you so much for your information.

    TOM: Happy to help you out.
