You can replace the word “clean” with many fancy substitutes. Such as spotless, scrub, cleanse, gleaming, speechless, unblemished, hygienic, unsmudged, showered, unsoiled, unspotted, and laved. To add more flavor to this word, you can say squeaky-clean, neat as a pin, tidy, well-kept or apple-pie order. You can make the terms as fanciful as possible, but make sure that your message is clear.
