What is the appropriate tool to use in order to remove glue residue from the natural nail?

The appropriate tool for removing glue residue from the natural nail is the fine buffer block. This tool is designed to gently buff the surface of the nail without causing damage or removing too much of the natural nail structure. The fine grit of the buffer block effectively smooths out and removes residues while preserving the integrity of the nail.

Using a fine buffer block minimizes the risk of creating scratches or excessive wear on the nail, which can happen with coarser materials. It allows for a controlled and safe approach to cleaning the nail surface, making it ideal for this specific task.

Other options, like a metal file, could be too abrasive and may lead to filing the nail down too much or causing injury to the nail bed. Cuticle remover is typically used for softening and removing cuticles rather than glue residue, while an abrasive buffer might be too harsh for this delicate task, risking damage to the natural nails. Thus, the fine buffer block is the best choice for effectively and safely removing glue residue.
