How to Clean Plastic Planters So They Look Like New Again

2 Materials
10 Minutes

I'm a Southerner & we Southerners love a good front porch!

No Southern home is complete without a fern or 5. But every year like clockwork, the urn planters I have my ferns in seem extra dirty.

That's not a good look especially since they are on the front porch on either side of the front door. Plus it's just not good feng shui.

So every year, I pull out the petroleum jelly & a rag & get to work cleaning them. I knew there had to be a better way so this year, I tried something new.

As you can see, we have 2 large ferns flanking our front door. After Winter Storm Uri hit in February, they didn't make it even though we got them inside early.

It also seemed like the pots were dirtier than normal this year. I'm not sure if that was because of the potting soil we topped them off with, but the planters were just a mess!

I pulled the planters out into the yard, cut back the fern fronds down to soil level, & hosed off the planters.

After they dried in the sun, I grabbed the WD-40 instead of vaseline this time. I figured it had to have the same effect - oil displaces practically EVERYthing - and I would have to buff it on & off like with vaseline.

This was really easy because it's like spray painting. Only faster.

After spraying the planters down I just let them dry before I put them back onto the porch.

And that's it! Quick & easy and I think they look better than new! An extra bonus is that the WD-40 doesn't seem to wear off as fast - water & dirt don't "stick" as much so the plastic is staying clean.

Now if only my ferns would grow back!

    Why is WD40 better than just spraying them with glossy black spray paint?

    They look great but wouldn’t the planters have an oily residue on them even after they’ve dried?

    Vaseline is a byproduct of the oil drilling industry. WD-40 is made with fish oil. Which one do you think it's better for the environment and your own health? It's a no-brainer.

    I tried ArmorAll original on some of my black landscape items and it’s working great. Plan to do my wrought iron furniture when I have time and energy. I sometimes use it on dirty shoes.
