1: You can use Blade Oil to keep the blade sharper for longer. Oiling the blades before and after every use will help the cutting performance and lifetime of the blade.
2: A great option for cleaning the blade is to use the Hygiene Spray after each trim, which will help it resist bacteria and viruses.
3: You can use Blade Ice to maintain the performance of the trimmer by keeping the blade cool. It also lubricates and protects against corrosion by blasting away hair and debris that might be caught in the blades.
