ultraclean
Beyond merely tidy
Ultraclean means extremely clean, beyond ordinary standards of cleanliness.
The term appears in technical contexts where contamination must be minimized: ultraclean laboratory conditions, ultraclean manufacturing environments.
It also describes rigorous environmental or fuel standards: ultraclean diesel.
In casual use, ultraclean simply emphasizes exceptional tidiness: The apartment was ultraclean when we moved in.
