How to make toilet more "slippery"? Hear me out.

We recently moved into a new home. In this new home our toilets work just fine and look fine. But...

I don't know if it's the Contours of the toilet or maybe they're old? But they all have this one spot on the way down where all poop sits and sticks if you are not flushing feverishly and immediately. Is there any technique or cleaning solution to help make that part less "glue" and more "slip and slide?"
