Life: Cleaning Around the Washer's Door?

In my attempt to be cleaner, I reached my washer and dryer. There is a lot of dirty stuff between the washer's door and where it connects to the rest of the washer. I am unable to reach in the opening with a paper towel which requires a lot of scrubbing. I've already cleaned most of the front which took quite a lot of force to clean off.

Surprisingly, I couldn't find something helpful on google (not sure if I'm using the right keywords like washer vs washing machine). I'm going to try slowly scrub away at it over time and hope that helps (which seems to help with the stove).
