What product is commonly used for cleansing gel nails before application?

• A. Purified water
• B. Alcohol or acetone
• C. Dish soap
• D. Oil-based remover

Answer: (B)

Using alcohol or acetone to cleanse gel nails before application is essential for preparing the nail surface. These solvents effectively remove oils, dust, and residues that can interfere with the adhesion of gel products. Proper cleansing ensures that the gel adheres well to the nail and lasts longer without lifting. Alcohol is particularly effective due to its quick evaporation and ability to disinfect, while acetone is a powerful solvent that helps in removing any remaining product or oil.

Purified water, while clean, does not effectively remove oils or product residues and could potentially lead to a poor bond. Dish soap is designed for cleaning grease and food residues but may leave behind a film or moisturizing agents that can inhibit adhesion. An oil-based remover is specifically meant for removing nail polish and may leave oily residues on the nail, which would also prevent successful gel application. Thus, alcohol or acetone is the most appropriate choice for preparing the surface of the nails before applying gel.
