Use 「潔癖」 for an extreme loathing of dirt or a refusal to tolerate any dishonesty; in speech it often appears as 「潔癖症」. For a merely tidy appearance, say 「こぎれい」 or 「身ぎれい」. The other near-synonyms describe honesty, fussiness, or a neat look rather than a loathing of dirt. The opposites are 「不潔」 and 「だらしない」.
