I noticed water backing up into my sink when my dishwasher drains. Oh no, I thought. A partial blockage. I used some Liquid Plumr.
Side note, you go to the store, and there’s big jugs and small jugs and three brands and liquid and “gel” and one part and two part…I don’t know if you’ve seen that youtube short of a tiktok of a Tumblr post talking about how there’s no such thing as “glue”? Well this reminds me of that because who the fuck knows what these substances are?
Anyway I bought one and followed the directions and it didn’t work so I’m probably going to have to take my sink drain apart which isn’t going to be fun.
It isn’t clear if it is draining slowly. You need something to physically remove the obstruction and something like this works really well for hair and might work for fatty stuff in a kitchen sink.

If it doesn’t work, at least it was cheap.
