I know, seems like a no-brainer huh? So much so that why would someone write an article about it!
Well, from my experience, sometimes those buckets have a mind of their own.
When you place one bucket inside the other, usually you can get them apart quite easily. Other times, you want to smash the crap out of them because no matter how hard you pull, they just won’t budge.
Here is a method I have found that will usually get those stubborn buckets apart.
Fill a larger container with warm/hot water. This container must be large enough to sit the buckets into.
Next, fill the top bucket with cold water. the colder the better!
Now, sit both buckets into the container with the hot water. You want just the bottom bucket in the hot water.
Wait a few minutes and then try to pull the top bucket up and out of the bottom one. Usually, the expansion of the lower bucket by the hot water and the contraction of the upper bucket filled with cold will allow you to get them separated.
Do you have a different way of getting 5 gallon buckets apart?
