1_ Cleaning and maintenance (sponge is recommended for cleaning) Use a general neutral detergent (or baking soda) and sponge to clean it. If the food dries out on the titanium, it can be soaked in hot water before washing. Titanium products in the hollow layer (double layer) are strictly prohibited to be boiled in hot water, and directly heated by an open flame or other methods. The gas in the hollow layer will expand and damage the product.
2_Titanium will produce nicks on "ceramics" because when titanium comes into contact with ceramics, it will cause the normal reaction of titanium dioxide residue, which is safe, non-toxic and harmless.
3_Titanium produces discoloration in high temperature. At high temperatures, the titanium dioxide film on the surface will have different thicknesses, and the thickness will be refracted by light to reflect colorful and different colors, which cannot be restored after discoloration. It belongs to the characteristics of titanium itself, and is safe, non-toxic and harmless.
