Investigating Towel Rack Rusting

Brass-Plated Chrome Towel Racks: The raw material is brass. The rusting process of copper differs from that of iron. Customers have reported the following reasons for rusting on their chrome-plated copper towel racks:

1. The plating was not properly protected, leading to damage. When brass comes into contact with air, "verdigris" may develop.

2. Infrequent wiping allows water residue to accumulate, forming dirt and eventually black spots.

3. Poor water quality containing metal ions, combined with infrequent wiping or uncleaned areas, can cause rust to form over time due to the interaction of water droplets rich in metal ions with air.

Aluminum Alloy Towel Racks: Pure aluminum products have relatively low hardness and tend to blacken. However, aluminum products undergo surface oxidation, significantly increasing hardness and preventing blackening, while also exhibiting excellent wear resistance. Although aluminum can rust, the rust forms a dense protective aluminum oxide film, preventing further rusting. Stainless Steel Towel Racks: Lower-grade stainless steel will rust. The higher the chromium content, the less likely it is to rust. 304 stainless steel contains 18% chromium, has good stability and strong corrosion resistance, and will not rust even when exposed to a humid environment for a long time.

Zinc Alloy Towel Racks: Zinc alloy towel racks will not rust. However, their quality is not as good as other materials, and they are more prone to breakage.
