Can anyone tell me if there is a way to clear the panoramic window in the main room of the base?
I've tried using a mop and a sponge with soap and water, but nothing changes.
I remember that in older builds you could do it with a sponge, is this feature removed?

I'd be very grateful for a hint!

Sponge dipped in water allows you you clean a small spot.

if you grab a bucked and dip it in the water it can hold a couple dips in it.

I think the pressure washer works that you can buy in the shop.
