It’s just you’re raking leaves. とはどういう意味ですか?

Is this paragraph about how to clean your tongue? Or how to use a tongue scraper?

“Its just you are raking leaves.” That doesn’t make sense. I need more details to figure it out. But, a “rake” is about the size of a broom, but has claw like hand instead of bristle brush at the bottom...and it is used to gather leaves together when they fall from the tree. So, that is called “rake” What you are doing is “raking the leaves.”

The next sentence seems like they are telling you how to use a “tongue scraper” to clean off the white coating on your tongue when you brush your teeth in the morning.
I have one...i think the person telling you how to use a tongue scraper, by saying that “it is like raking leaves.”
