From sweet and salty soaps
Our customers consciously choose stainless steel as a material. Stainless steel combines elegance with high durability and stability. And now, after only a short time, this supposedly 'rust-free' stainless steel product is showing discoloration or rust spots? It's reasonable to assume that this must be a material or manufacturing defect.
Why is my "rustproof" stainless steel product rusting?
Of course, manufacturing defects can occur, but this is rare. Much more often, the cause is quite simple: soap. Stainless steel has a passive layer that permanently protects the surface from corrosion. However, if this passive layer is destroyed, even stainless steel becomes susceptible to corrosion.
Contact with salts such as bromides, iodides and chlorides or ammonium further increases the corrosive effect.
Which soap can I use without hesitation?
Due to the large number of soaps available and the constant changes in their formulas, we unfortunately cannot give specific product recommendations. The soaps we offer can be used without restriction. Should you wish to use a third-party product, please carefully check the ingredients. Strong acids, bases, and salts such as chlorides, bromides, iodides, etc., should not be included, as these can cause corrosion when in contact with stainless steel. If your soap dispenser is equipped with a reservoir cap, please be sure to use it. The evaporation of soap ingredients can produce aggressive gas mixtures that can also be corrosive.
The correct fastening
Contact with base metals can also damage the passive layer. Pay particular attention to using high-quality fasteners such as stainless steel screws and washers.
