20 gallon stability

[Searchin]

So I have a 20 gallon tank that I use for my hermit crabs. Over the last 4 years that I've had them, one rinsed the tank out many times. Sometimes I've used super hot water.

My questions:

Have I compromised the integrity of the seals by rinse the tank with hot water?

Do you think it will hold water ok?

Set your tank outside and fill with water. Let it sit for 24hrs and come back I check for any leaks. If there are no leaks then you are probably fine.
