How do you access/clean T@B 400 square bathroom fold down sink "cistern"?

Title kind of says it. I have a 2022 T@B 400 with the square fold down bathroom sink. The sink drains into a cistern/basin below it. To access the complete surface area of the cistern for cleaning is near impossible and that area gets as dirty or dirtier than the sink itself.  You can't get you hand behind it when the sink is down or beneath it when the sink is up.  It would be nice if the fold down portion could somehow be removed easily for cleaning but the pivot points seem to be integrated into the structure.  

Are there some special methods/tools people use to clean the cistern surface?

    You could try a good spray on surface cleaner to loosen any accumulation and rinse it out?  A small brush, similar to a toilet brush might fit in with the sink tilted part way up?  I eliminated the issue, by not having the sink to start with.  B)

    I don’t like the square sink in the 2022 t@B 400!  It doesn’t drain easily. When you fold it down to use it, you are practically standing outside the bathroom to use it because it’s so big.  Is it possible to replace this sink for a corner oval or round sink?

    The folding sink was the source of a lot of headaches for many, which is why NuCamp dropped it finally for a corner sink in later models.

    There are several threads on changing out the sink if you are handy. We took our round sink off and after consideration decided that extra space was more valuable, particularly when taking a shower. But others have chosen other sink options.

    This one has lots of pictures of behind the sink and show the plumbing variations you might encounter
