When you cast this spell, select a 10-foot square section within range.

Any foreign substances on the surface of the square that you specify such as dirt, blood, toxic chemicals, paint, ink, and so on vanish harmlessly, leaving the surface clean and sanitary. This cleaning makes it impossible to track a creature through the affected areas via mundane means, but the utter cleanliness may itself be suspicious.
