Editor's note
Polish that has flooded the cuticle or drifted onto the skin is not a failed manicure — it is an unfinished one. The cleanup step exists precisely for this. A small brush loaded with acetone removes polish from skin without disturbing the nail plate underneath. The technique requires a light touch. Trying to clean up wet or even surface-dry polish drags the colour and creates a worse edge than the original mistake.

What nail cleanup actually means
Cleanup refers to removing polish from the skin surrounding the nail after polish has been applied and dried. It is a standard finishing step. Even a technically clean application almost always has minor polish on the skin. The tools are a small angled brush loaded with acetone, or a fine-pointed cotton bud.
Myth, meet fact
- Myth: You should clean up polish while it's still wet. Fact: Wet polish smears and acetone on wet polish bleeds under the nail edge. Wait for polish to dry fully.
- Myth: A cleanup brush cleans the nail edge at the same time. Fact: Acetone dissolves polish on nail as readily as on skin. Load minimally and work only on the skin line.
- Myth: Cotton buds work just as well as a cleanup brush. Fact: Cotton buds are useful for larger corrections. For a precise cuticle line, an angled brush gives more control.

Cleanup tool, by situation
Angled cleanup brush as the primary tool for cuticle line precision. Fine pointed brush for tight corners and sidewall corrections. Standard cotton bud for flooded cuticle or larger overflow areas. Pointed cotton bud as a versatile middle ground. Toothpick dipped in acetone for spot debris only. Corrector pen for travel use.
