Let dry.  No matter what organic solvent cleaning method is used, the drying process must not be omitted, otherwise the meaning of cleaning will be lost.  Anodized aluminum profiles Principle of anodization: Use aluminum or aluminum alloy products as anodes and place them in an electrolyte solution to use electrolysis... The common method is direct current sulfuric acid anodization.
