Cleaning Moss From Concrete
LESLIE: Alright. We’re heading over to Washington to talk with Jean about moss. What can we do for you?
JEAN: Well, I would like to know, is there a product that I can use safely on blacktop or cement to get rid of moss?
TOM: Yeah. You can use trisodium phosphate – TSP – which you can buy in the aisle of a – paint aisle of a hardware store or a home center.
JEAN: OK. Then if you spray that on, do you need to also wash it away and wash it off?
TOM: Yes. Yeah, you do. You need to let it sit there for a while and you can scrub it and then rinse it away.
And then another option is a product called JOMAX. And that’s available at home centers and hardware stores, as well. And that’s made by the Zinsser Company. And that’s a house wash and mildew-stain remover, so that’ll work well on the algae, too.
JEAN: OK. And is that a spray-on?
TOM: You mix it up and you spray it on. That’s correct.
JEAN: OK. And then do you think you need to rinse it off, too?
TOM: I would follow the label directions. I believe you do. And that will take care of it, OK?
Good luck with that project. Thanks so much for calling us, Jean, at 888-MONEY-PIT.
