Why has my e-file bit discoloured?
The discolouration of metal items such as e-file bits and nail tools is due to oxidation, which can occur when metal is exposed to air and moisture for an extended period. This oxidation process can lead to the gradual erosion of the coloured coatings and the exterior of the metal on the bits. Tarnish and discolouration occurs gradually when the surface of metal is exposed to air and moisture. A chemical reaction begins to take place (known as oxidation), as the metal reacts with sulphur in the air which in turn, starts to form a dark layer all over the items in question.
To help mitigate this issue, we recommend following the manufacturer's guidelines for disinfection of your e-file diligently. Ensure that you do not leave the bits in disinfection solution for longer than the recommended time and always thoroughly dry them after cleaning. It is important to thoroughly dry your metal tools with a low heat hair dryer or microfibre cloth, concentrating on crevices, hinges, knurling, after each use and store them in a dry, moisture-free environment. Another cause of discolouration or tarnish can be due to a chemical reaction. The chemicals commonly used in nail services, such as acetone and other solvents, can react with the metal surfaces of your tools, leading to discolouration and corrosion. To prevent this, it's crucial to clean your tools regularly with solutions designed for this task and to avoid prolonged exposure to untested solutions.
Environmental factors such as exposure to air, temperature fluctuations, and airborne pollutants can also contribute to the degradation of nail tools or e-file bits. Storing your tools in a cool, dry place and minimising exposure to environmental contaminants can help preserve their integrity.
You may be able to remove this, but there is no guarantee with a long soak in a mild detergent (washing up liquid works well) and hot water followed by a gentle scrub with a soft brush. Make sure to rinse any solutions off and dry thoroughly to prevent oxidation from oxygen and water. You can use a low heat hair dryer to ensure these are thoroughly dry.
