If the environment is harsh, the higher the probability and speed of stainless steel rust, for example, there will be salt in the air in areas by the sea, such an environment is more prone to rust; there is also a renovation environment dusty and chaotic, high acidity, may also accelerate the oxidation; even stainless steel should be cleaned up the surface in time. In addition, stainless steel is a generic term, there are actually more than 100 different kinds of stainless steel, each with a different antioxidant capacity. The most common in everyday life are 201, 304 and 316 stainless steel, with increasing oxidation resistance in that order.
The most commonly used in renovation is 304 stainless steel, which may be used for sinks, floor drains, pendants, doors and windows, etc. The 201 grade stainless steel has a weaker oxidation resistance and is not recommended. 316 is generally used for shipbuilding and has a stronger corrosion resistance, and is used less in everyday products.
To answer the question of rust on the surface of the stainless steel sink at the beginning of the article, if it is a very small bit of rust, this is called "floating rust" in the industry, not necessarily stainless steel rust itself, but also may be the dust in the air containing iron ions caused by the oxidation. If you can't get rid of it with your bare hands, you can use something like "Five Cleaner" or "Stainless Steel Rust Remover", which are available online.
In fact, apart from stainless steel, brass is also subject to oxidation, but the oxidation of copper produces a greenish colour. So generally the products in the decoration are made of antioxidant coating on the surface, such as surface chrome and nickel or other antioxidant materials, if the coating rubbed will also accelerate the oxidation.
Finally, Zheng suggests that in daily use, these faucets, showers, hardware pendants are also in need of maintenance, such as a period of time to clean the surface. Also, the renovation process, the site environment is relatively harsh, these metal products installed, remember to do a little cleaning and protection work, such as floor drains installed after the cement are not wiped clean, over time wipe can not be wiped off, and also very easy to accelerate the surface oxidation.
During the renovation process, whether the site is neat and tidy, whether the rubbish is cleaned up in time, whether the completed project is well protected is also an indicator to measure the renovation company or workers. If the workers don't care, we have to care ourselves, after all, the house is their own, the materials are bought at a high price.
