게 닦다

wipe or scrub it somehow

닦다 is wiping or scrubbing something clean — tears, a table, orchid leaves, blood off meat. -게 gives the manner, and here it is usually 이렇게 or 그렇게 with the speaker demonstrating; the exceptions are 부드럽게 닦아 줄게요 (I'll scrub him gently) and 핏물 가볍게 닦아주고 (wipe the blood off lightly). 닦아주다 means doing the wiping for someone or something else.

Register: casual, demonstrating
