Hello, our lanai is dirty when it rains like this. Blackish stuff. What do you use to clean an open lanai floor?

[Phanatic Luvr]

Hubby hoses our lanai out all the time. He uses a stiff broom and a little Dawn dish detergent and then hoses it out. Easy

Try a pressure washer

I scrubbed ours yesterday with a bucket of dish detergent and a little bit of bleach. Used a stiff broom.
