Few things feel better than a clean kitchen!
Mainly used lukewarm water to clean over surfaces. The floor was swiped. For the dirty bottles and some spots on the walls, I used a probiotic and biodegradable cleaner, based on effective microorganisms - similar to the ones in bokashi, I think? To get the bottles clean, they were swirled out with some uncooked rice grains and
hot water+cleaner.
As a bonus, for this BB I re-learned how to use Gimp/Gnu to merge pictures together (to avoid a zillion pics in the post). For others wanting to do the same, the how-to is available
here.
Edit: added a picture with more info about the cleaner. It doesn't explicitly say "greywater safe", but there's a picture of a loo and the text says "The probiotic effect also reaches our drainage and sewer systems which is a great
boost for the environment!"
I don't know how much stock to put in this statement, perhaps if everyone used this product for all their washing it would make a difference...however, looking at the ingredients list it
should be safe to assume that it will readily degrade with no ill effects. "Acetic acid" is the acid in vinegar.
