What's the trick to preventing stacked plastic buckets from sticking together? (2025 Update)

Easy if you are near hot water.

No. I've tried it. I've tried pretty much everything except drilling the bucket for a tire valve and using an air compressor.

The problem is the side forces. If the two buckets were exactly centered together, concentric around a common vertical axis, then the only forces resisting would be the friction from the point where the bottom of one contacts the side of the other.

But that's not how buckets nest. One is always tipped slightly, and that makes it near impossible to extract.

Try it yourself with a couple of plastic drinking glasses.

If they're not too fragile after having been outside in the sun for ages, I sometimes throw them onto concrete or the hardest soft ground I can find.

It only works about 1/2 the time (never on the strongest bonds). Then I pry.

When I ponder drilling a hole in the bottom to insert an M80, I give up.

But I agree with all that sometimes they're damn hear impossible to separate and I always wondered how the friction could be that super glue strong.

To KEEP them from sticking put a piece of cord, or even a "slat" of corrugated cardboard between the buckets when you stack them and they will come apart slick as goose poop

...or a small length of 2 x 3, 4, etc.

Makes the stack a little taller but they don't even think about sticking.

I looked up "tubafor" and nothing addresses this issue. What are you talking about!

Good idea, done this - trouble is if you plan on hauling/holding liquids, they will leak - just be prepaired to patch with a little silicon!

What the heck is a tubatoo?

Great idea!!

A stick of lumber tu nominal inches by for nominal inches.

Just throw a huink of twine over the edge of each bucket before stacking them and they come apart like butter.

I use the same 2 gal buckets for maple syrup. When done using them I clean them thoroughly then wipe some vasoline around they bottom edges with the vasoline, And repeat all the others the same. The vasoline won't damage the buckets and helps prevent them to seal together. Seems to work for me as there stored away for next season .

Must improve the flavor of the syrup too.
