Unblemished means without any mark or fault. An unblemished record, unblemished skin, an unblemished reputation.
It is used far more of records and reputations than of surfaces, and it makes a strong claim — one lapse is enough to end it. Note blemish beneath it, from an Old French word meaning to make pale or damage.
