So, I know there's すっきり for neat rooms etc., ぴかぴか for something shiny, and きゅうきゅう for cleaning itself, but is there an onomatopoeia in Japanese to show that something has just been washed or cleaned enough to squeak?
きゅうきゅう sounds close, but I don't feel like it can be used for the state of being clean itself.
Interestingly, I found this question about 'squeaky clean' when searching for this...
きゅうきゅう for cleaning itself
-- You mean きゅっきゅっ, no? E.g. 「きゅっきゅっと磨く」- polish clean, cf. 「きゅうきゅうに詰める」- pack tightly
