The TRASS products are made of stainless steel type AISI 304; AISI 306 and 306L. Outdoor ones only made in 316L. 
Basic maintenance consisting of normal cleaning with water and neutral ph soap is required. 

The product can be damaged by different factors: 

  1. LIME: lime in the water can remain attached to the product and create marks if not cleaned away.Rinse and dry with a soft cloth when finished. 

  1. ABRASIVE ELEMENTS: NEVER USE SUBSTANCES THAT INCLUDE DETERGENTS, CHEMICALS, ABRASIVE or METALLIC SPONGES, SOLVENTS. If product is exposed to acids, abrasives, or other corrosive materials  the product can be altered in its atomic structure developing rust and staining rapidly. Special care must be taken with current cleaners that have become so popular as cillitbang, KH7, etc ...  they contain high amounts of corrosive agents and if applied to the steel, it should be rinsed with water and dried to leave no traces of these liquids in the steel and prevent spoilage. Cleaning products as hydrochloric acid or lye should also be used with caution, and even used in remote areas from the steel, in the case of being in the same room and not having ventilation, the vapors can condense and affect the layer producing exterernal stains and rust. In the case of use, it is advisable to ventilate the area and clean the products once the effect of the vapors is zero and the area has been ventilated. Near the seaside where this material is in direct contact with the sea breeze, application of  paraffins and other specific protective prescripted liquids is advisable. Recommended also daily cleaning of these products with mild soap and water for their perfect durability and conservation over time. 




  1. Periodically clean the aereator filter in order to prevent lime or other elements blocking the  


  1. In case of using neutral ph soap sprayed, never use directly on the product’s surface.  

      Spray in a cloth or dry soft sponge. 

5-   Do not use tools for installing the hoses.  




  1. Our products are manufactured only in Stainless Steel DIN 1.4404 / AISI 316L; 

  1. You need to connect an earth electrode in the support (water cannons, pool waterfalls, air-massage beds), to divert  the static current produced by the electronic  parts. 

  1. The use of anti-sand filter is advisable to avoid blocked  faucets . In case of this kind of failure, it will be excluded from the warranty. 

  1. Check the ph of the water, it should be neutral. Any higher or lower ph may damage the steel and would be corrosive to it.. 

  1. Check the water’s salt level , it also should be appropriate. (information provided by the manufacturer of equipment). A higher or lower level, may cause damage and would be corrosive for the stainless steel. 




If you develop external jobs/works around the stainless steel productslproducing iron particles, it may affect the stainless steel surface and alterate its properties.It must be removed immediately. Steel dust particles crated during operations such as welding, cutting, drilling and grinding of carbon (non-stainless) steel will rust quickly. Besides corroding themselves, these particles can locally break the self-healing (passive film) of stainless steel resulting in pitting corrosion in spite of their normally good corrosion resistance. 




To remove fingerprints and normal soiling, soapy water or a mild detergent are usually safe and successful. 

Mirror-polished stainless steel can be cleaned with glass cleansers. These products should be selected chloride-free. 

Where water has been used for cleaning or rinsing, wipe the surface dry to prevent watermarks, especially in hard water areas. The use of deionized water will prevent the formation of hard water staining. 

A damp cloth or chamois leather will usually be suitable for removing normal soiling, fingerprints, etc. 

Do not use steel scouring brushes or metallic strippers. 


Cleaners that should not be used on stainless steels include: 


  • Chloride-containing cleansers, especially those containing hydrochloric acid, 

  • Hypochlorite bleaches should not be used on stainless steels; if applied accidentally or split on stainless steel surfaces, should be rinsed off immediately with liberal amounts of fresh water, 

  • Silver-cleaners must not be used on stainless steel. 


The avoid “cross-contamination” from iron particles, ensure that cleaning utensils have not been used for “ordinary” (i.e. carbon) steel before. Cleaning materials for use on stainless steel items should preferably be reserved exclusively for that purpose. 




On building exterior applications, stainless steel may be exposed to a wider range of potentially more aggressive environments as a result of contact with: 


  • Marine atmospheres 

  • Environments laden with industrial pollutants, 

  • Salt spray from road de-icing salt 

  • Atmospheric dirt and traffic film. 


All cause brown staining to appear. It is a good to clean the stainless steel products more frequently if required.
