How to deal with oxidized white spots on stainless steel pipe fittings

White spots are formed on the surface, and corresponding treatment must be made at this time, but how should we deal with it?
　　 1. Surface polishing method.
　　 Polishing can fill the pores of stainless steel pipes with the ground aluminum powder.
　　2. High voltage and high current density impact method.
　　In the early stage of anodizing, high-voltage and high-current impacts are used, so that large and small stainless steel pipes that were previously cut by impurities are connected into pieces by high current impact.
　　 3. Exterior shot peening method.
　　 Because the power of shot peening will be greatly improved, the effect of such stainless steel pipe fittings after anodizing and dyeing will be surprisingly good.
