How to Deal With Rusted Paint Cans
Have you ever opened a paint can only to find the top had become rusty? You have a few choices on how to deal with rusted paint cans.
- Use the paint from the can and take a chance of the rustiness getting on your brush.
- You can pour it into a container to use for your current project.
- You can throw it out.
- Or you can do what I’m going to show you.
If that has happened to you, you know it’s nearly impossible to reseal a can like this to keep your paint in decent condition.

Repurpose Laundry Detergent Jug
I’ve found that it’s better to stir it up and carefully transfer it from the rusted paint can to a detergent jug for safe keeping.
TIP: You must rinse out all of the remaining detergent. I generally fill with water, shake, empty, repeat several times. Then I fill the jug with water and let it set for awhile to loosen any buildup, then rinse, shake, repeat again.
Strain Old Paint
I have a couple of mesh paint strainers. You can pick them up at your local hardware store or on Amazon– 1 Gallon Elastic Opening Strainer Bags 6 Pieces.
Using caution while stirring your rusted paint can is a must. You don’t want those rusty bits to drop into the can.
As you can see, the paint is rather goopy toward the end of the can, but because I used the strainer, I know there are no clumps in the jug.
I decided it would be less messy if I pushed the strainer further into the jug. To make things easier, you could pour the paint from your rusted paint can into a bucket with a paint strainer and THEN into the detergent jug.
Clean Up The Messy Jug
You can see that the spout makes it difficult for the paint to get in the jug. I wiped it off and continued painting.
The next time I wanted to save some paint, I used a different jug. I removed the spout to get the paint into it.
I didn’t strain this can of paint because it was a brand-new gallon of paint.
After I poured the paint into the jug, I replaced the pour spout to make it easy to pour paint the next time I use it.
Mark Your Laundry Jug With the Proper Description
I used a marker to identify the brand, type, and color of the paint.
With the ERA jug, you can even see the amount of paint and the paint color in the little window. You can’t do that in a rusted paint can.
I have identified the color on this one as well.
Perhaps you’re on team “store paint in a mason jar.” I am not of that persuasion because I store my paint wherever I can find a spot. If stored up high, I can see that mason jar tipping off the shelf and landing with a big SPLAT onto the floor.
No More Rusted Paint Cans
So, if you have a surplus of laundry detergent jugs and are a paint hoarder like I am, you’ve got it made!
This pallet top table was painted with my oldest batch of paint, and LOOK, it’s stored in an old plastic milk jug. Seriously, that paint is probably 10 years old.
For this Vintage Sewing Drawer Makeover, I used a coffee creamer container to store DIY Chalky paint.
Do you have a great tip for storing paint? If so, please leave it in a comment below.
How about using some old paint to make your DIY Chalky Paint Primer? The best part about making your own primer is that your first topcoat will go on perfectly because you’ve already used that color as a primer! It’s a win/win!

Use bigger empty plastic bottles of water. Just dry them out, fill them up, cap them, write on the plastic bottle the drying time, manufacturer and code of paint..
Many gallons today are made in Chi… they rust quicly as they lack anti rust treatment
Transfer your paint as the gallon is new, dont wait till its rusted
GREAT IDEA Thank you for sharing.
I just opened a gallon of white semi gloss and the can was rusted. I closed it up again and planned on buying another can. Thank you for this great money saving tip!
Yeah, I don’t like to store my 2 paint cans upside down. And the rust gets on paint cans because the lids aren’t put back on tight enough, letting air and moisture inside the cans. I wash the paint off the lid after I’ve used it (I only use water-based paint I hate oil), wash it off the top of the can (I save lots and lots of old rags for cleaning), then everything is nice and clean to put the lid back on the can. Then I hammer it on with a rubber mallet (don’t use a metal hammer, that’s great way to dent the edges of your can). Sometimes if it’s stubborn to go on I’ll use a flathead screwdriver in the crevass of the lid and hammer on that. But cleaning the paint off the lid and can before putting the lid back on can save a lot mess, and you get sudden “splats” of paint off the edge of the can as you hammer the lid back on. Taking the time to be clean now can certainly be of great benefit for future use of things. I don’t get any rust on my cans.
I meant to say, “save you getting sudden “splats” of paint…..”*
All great tips! This particular can was inherited by me. I was not the one that let it get in such bad shape. 🙂

Would be handy if paint companies just put it in jugs in the first place!
I totally agree Karen! 🙂
Dutch Boy is the only one I know of that does have plastic jugs. But their lids are difficult for these old hands to open!

Smart, smart, clever, thrifty, eco-friendly idea. Recently I had numerous paints left over from repainting the house. I bought a case of 24 quart canning mason jars for $8. Poured my paint in them, labeled the top of each jar and stored them back in the case in which I bought them. They stack neatly on my storage shelves with no debris inside each jar & the color easily visible
I was just asking at HD the other day if they had plastic “cans” to store paint in. (They didn’t) This is brilliant, Gail. I’d add one thing, a sample colour swatch somewhere, either on the lid or taped to the side. Thanks, now to find some detergent jugs, they take so long to use up!
I LOVE clever people like you, who make life SO much easier for unclever [is that even a word? :] people like me. Thanks bunches!!
Thank you Chris! I’m happy to share any and all pieces of advice and tidbits. 🙂

Brilliant. Simply brilliant!
Great idea! It certainly makes it easier to pour!
Nice! We use those orange juice containers from the dairy case–now that already made oj is cheaper than the frozen! They are clear, so we can see the color, and we use a homemade funnel to get it in there. Your idea is better, because the neck is bigger.
great idea for dealing with rusted paint cans! i think my Dad does the same thing.
