Salvage the contents of a rusty paint can.

Don't you HATE rusty paint cans? Especially when they're almost full of perfectly good paint or polyurethane? I was confronted by such a thing last week. If the can would have been almost empty, I could see (maybe) disposing of it and buying new, but this can, as you can see, was nearly full. To salvage the contents, here's what I did:

First I stuck painter's tape into the inside of the rim.

Then I poured the poly into a new can I picked up at my local hardware store.

More Hints!

  • To help prevent rusting of the new can, stick painter's tape onto the rim and draw your brush out along that edge.
  • If rust flakes off and into the paint/poly, you can actually strain it using an old pair of nylons or cotton cloth as you pour it onto your new rust-free can.

After opening a new can of paint, etc. but BEFORE starting to paint, hammer a small nail through the bottom of the of the channel that the lid fits into  to punch holes at 3-4 points around its circumference.  Whether you use a plastic "pouring lip" or not the holes will allow paint that gets into that channel to drain backinto the can.

The little rubber "lips" do not prevent the rust from developing. They do clean the paint out of the channel so the next time you open the can you won't have to worry about difficult stuck lids. But if you let the can sit for touch ups or it sits around for a year or so, you will still experience rust on the edges. I don't know why paint manufacturers don't utilize more plastic cans as this would seem to make more sense (unless they don't want us saving paint  and want us to rebuy a gallon for small touch ups

Better yet, pour it into a plastic paint container or other plastic container, like a cleaned peanut butter jar.  They sell empty plastic paint containers at most stores that sell paint. I hope the nylon filter material will catch all the rust particles since the paint I need to transfer is white ceiling paint.

thanks   i will try these hints!

Katie--I've seen those but haven't tried one. They seemed kind of gimmicky to me, but I'm glad to hear they really work!

They also make these little... lips that you can snap onto the edge of your paint cans that are super handy. The will usually have them on the paint counter, or near it, for about $.99. They're great for keeping paint out of the crack around the lid, wiping off your brush, and stopping all those messy drips. I almost can't paint without one and they're reusable to boot.
