How to Clean an Outdoor Playset

LESLIE: Erin in Ohio is on the line and needs some help with a playground. What can we do for you?

ERIN: I have a swing set/playset. It’s made out of treated wood and it’s about 10 years old. The flat surfaces, they’ve turned black and the wood is cracking. I’m wondering how I can best clean that up.

TOM: Well, the best thing to do is to use a wood cleaner. But let me ask you this: is it pressure-treated, this wooden playset?

ERIN: I believe so, yes.

TOM: Because, you know, pressure-treated lumber is unsafe for playsets because of the chemicals that are in the pressure-treated lumber leaching out of the lumber, getting into the soil and so on. So, I’d just give you a bit of a warning on that.

But if you want to clean this, Flood makes a product called Flood Wood Cleaner that works really well. Basically, you wet the lumber down, you apply the wood cleaner, you let it set for 20 or 30 minutes. You don’t let it dry – you may have to remoisten it again – and then you kind of scrub it clean. You can use a pressure washer after that to scrub it clean. It does a pretty good job of brightening up the finish, taking away the dirt and the grime and lifting up any of that old, gray sort of oxidation that settles on the wood or the black oxidation that settles on the wood.

You can find that at most home centers and hardware stores. And again, it’s called Flood Wood Cleaner.

ERIN: OK. Once I have it clean then, am I better, do you think, to stain it or paint it?

TOM: No, you’re better to stain it. What you want to do is use solid-color stain, as opposed to semi-transparent stain, because it’ll last a lot longer. The solid-color tends to fade a little bit better and doesn’t peel like paint would.

ERIN: And the same – like we have a swing – a porch swing – that I’d like to put on there, as well. Same thing then with that to clean it up? It’s been outside for some time.

TOM: Yes. If it’s natural wood, that’s a good product to clean it up with. And the same advice applies to the porch swing.

Now, is that also made out of pressure-treated lumber or is that something different?

ERIN: It’s about the same age. I believe it is.

TOM: Alright. So, again, use the solid-color stain.

ERIN: OK. Very good. Thank you.
