The local wheels put extra epoxy on their wheels to attract customers about the hardness of the wheel. In practice, the epoxy gets transferred in the form of black spots to the metal surface when heat is generated during polishing.
Sometimes the local product gives fast cutting during polishing because of cheaper quality iron content added in the ALOX. It is highly recommended not to use such products as they end up giving dullness and blackness after some days of use.
Notice: Rinse thoroughly before and after each use and squeeze dry. Especially when using with products containing bleach. Sanitize in the dishwasher or by bolling. Do not microwave. Not for aquarium use.
