How to say "immaculate" in Japanese

• 無垢むくCommon
  na-adjective, no-adjectiveCovers 'immaculate' as unblemished purity or innocence: a spotless heart or character, untouched and unsullied, rather than anything to do with physical cleanliness or tidiness.
• 清潔せいけつJLPT N3approx.Common
  na-adjective, nounUse it when immaculate means spotlessly clean and tidy — a room, clothes, or personal cleanliness — and it can also carry the sense of moral purity and virtue.
• 白いしろいJLPT N5approx.Common
  i-adjectiveReally just the adjective 'white': it describes blank paper or an unmarked, uncolored surface, and only evokes 'immaculate' through the image of whiteness, so it is seldom the word you want here.

Use 清潔 for immaculate in the literal sense of spotlessly clean, 無垢 for moral or spiritual purity and innocence, and treat 「白い」 as simply the color word white, which evokes spotlessness only indirectly.
