Stainless steel is the most durable material for washrooms. Compared to other common used materials like ceramic or composite materials, stainless steel is extremely resistant against vandalism, fire such as marks from cigarettes, commonly used chemicals like acids and is impact resistant. The material is colour-neutral and can be combined with all other materials and colours. Stainless steel is hygienic and easy to clean. Additionally stainless steel is 100 % recyclable and therefore environmentally very friendly.
How can stainless steel be cleaned most efficiently?
Remove any protective coating as soon as possible after installation. Stainless steel can age with exposure to light and heat. Avoid the use of liquids containing chloride, hydrochloric acids and abrasives. Brushes with bristles made of steel should also be avoided. Franke recommends the use of a wet microfibre cloth and the Franke stainless steel cleaners Twister, Inox-cream and Multiclean. Additionally vinegar diluted with water (20 % vinegar, 80 % water) can be used. Rinse off with clean, cold water after cleaning to remove the residue of cleaning materials.
Why does a stainless product rust?
Stainless steel can rust if the protecting passive layer on the surface gets damaged by the effects of external factors on the material. This can occur when the surface is in contact with chemicals like bromide, chloride or iodine. Please always use the mounting fixings delivered with the product such as the stainless steel screws and washers. Untreated welding marks can change the colour, this is not rust and does not affect the lifespan of the product.
Why to use MIRANIT?
This material is a stable compound consisting of approximately 80 % natural minerals such as calcium carbonate and quartz as well as approximately 20 % of a high-quality unsaturated polyester resin. The stable and fracture-resistant material has a smooth, pore-free and high-gloss exterior skin. The Gelcoat layer that provides the Alpine White colour is easy to clean, impact resistant, non-abrasive and offers good resistance to alkalines and acids. Even water temperatures up to 80°C will not harm the Gelcoat surface.
What are the advantages of MIRANIT compared with sanitary ceramics?
Sanitary products manufactured under the brand name MIRANIT can be classed under the generic term of "cast mineral products". Compared to other cast products such as ceramic sanitaryware MIRANIT products have the following advantages:
• Higher stability in terms of impact resistance and being shatter-proof.
• Clean shapes with good design and the use of small radii.
• A total length of 3.60 m can be achieved for niche washbasins.
• Damaged surfaces can be mended with special repair kits.
How can MIRANIT be cleaned most efficiently?
The Gelcoat surface is dirt repellent and particularly easy to care. In most cases a damp cloth is completely adequate for cleaning the washbasins, multiple washing facilities and cleaning basins. More serious soiling can be removed with mild, non-scouring cleaners. This also applies to colour pencil traces, shoe polish, ink, iodine solution and lipstick. Stains that could result from burning cigarettes, for example, can be removed with a polishing paste. For a sustained shine it is recommended to occasionally rub MIRANIT equipment products with commercially available car polish and then immediately repolish the treated surfaces. Any damage to the surface can be mended using a repair kit (EAN number 7612982005862) with which almost invisible repairs can be accomplished.
How is the product designed for robustness and vandal resistance?
Franke is a manufacturer of fittings in the public and commercial sectors. We produce self-closing fittings that are specifically targeted towards the requirements for hygiene and ruggedness as well as saving water and energy. Safety against vandalism is also a significant factor and we meet these requirements as the equipment supplier for prisons.
Are the products suitable for non potable water quality?
Basically our products are operated and tested according to EN816 with drinking water. Provided that the water is filtered, non potable water can be used as well.
Why are hydraulic or electronic fittings used instead of conventional products?
Self-closing fittings for facilities heavily frequented by anonymous users provide a much better service than conventional ones because of their automatic functionality. Hydraulically or electronically controlled fittings are available for washing facilities, showers and flushing systems and provide the means necessary for considerable water and energy conservation - either by pushbutton or completely touch-free.
Electronic fittings - for particularly effective conservation Opto-electronic fittings only dispense water when the user is in the sensor range. Shower electronics with Piezo-buttons also effectively reduce operating costs with split-second adjustment of the maximum flow duration and an integrated start/stop function. In addition, the use of electronic fittings enables a large number of special functions such as hygiene flushing, thermal disinfection, pre-flushing, the reduction of flow time independent of the frequency of use and more.
What must also be observed for fitting maintenance?
As the formulas of commercial cleaners are frequently changed, we can not guarantee that they treat the fittings gently. In general, observe the following for fitting maintenance:
Only use cleaning agents that are intended for this application area
Never use cleaners that contain hydrochloric acid, formic acid, acetic acid, phosphoric acid, chlorine bleach or acid cleaners (caution: stress corrosion) that might be used for cleaning ceramic wall and floor coverings
Mixing cleaning agents is generally not permitted
Do not use abrasive cleaning materials or equipment such as unsuitable abrasives, pads or microfibre cloths
Do not use high pressure cleaners
Apply a cleaner suitable for use with a cloth if fogging occurs
Cleaning method for chrome fitting surfaces
Follow the instructions from the manufacturer of the cleaning agent
Clean as required, i.e. depending on the degree of contamination (dirt and lime scale) and the area of use (e.g. food industry or service area)
Adjust the cleaning agent dosage and application time to the specific requirements
Do not leave the cleaning agent on for longer than necessary (maximum 30 minutes)
Rinse with clear water after cleaning and completely remove any remaining residues (as otherwise small black colourations become visible - long-term damage)
Never mechanically remove incrustations
Prevent the build up of lime scale by cleaning regularly
Never apply cleaning products directly to the fitting (if necessary, existing lime deposits can by removed by directly applying the cleaner on a cloth)
Never spray cleaning solution on the fittings but on the cleaning cloth as the spray can penetrate the openings and columns of the fittings and cause damage
Body care products such as liquid soaps, shampoos and shower gels can cause damage and must be removed after use

Why does Franke supply screws and dowels?
The use of wrong materials can cause corrosion when getting in contact with stainless steel. Therefore Franke supplies stainless steel screws and dowels as a special service.
Why does Franke supply mounting fixings for concrete walls?
Concrete walls are the most common surface used for fixing the Franke grab rails. As special service Franke supplies the screws and dowels for these wall types together with the product. Because of the huge amount of possible wall types and surface finishes, we cannot offer fixings for this variety of surfaces. The correct fixing to the wall is an essential part of the overall product security and this is the responsibility of the installer.
Which soaps can be used?
Because of the large amount of available soaps we are not able to give suggestions for products to be used. Franke recommends the soaps offered by Franke. Please check the ingredients very carefully. Liquids in contact with stainless steel must not be strong acids or salts like chloride, bromide, iodine and similar chemicals. These chemicals in contact with stainless steel can cause corrosion. If your soap dispenser is equipped with a tank cover make sure that it is in place. Evaporating of ingredients can cause aggressive gases which also can be very corrosive. Disinfectants act very aggressively on the seals of the soap dispensers.
Can disinfectants be used in soap dispensers?
Because of the large amount of available disinfectants we are not able to give suggestions for products to be used. Please check the ingredients very carefully. Liquids in contact with stainless steel must not be strong acids or salts like chloride, bromide, iodine and similar chemicals. These chemicals in contact with stainless steel can cause corrosion. If your soap dispenser is equipped with a tank cover make sure that it is in place. Evaporating of ingredients can cause aggressive gases which also can be very corrosive. Disinfectants act very aggressively on the seals of the soap dispensers. If the pump gets damaged by the use of aggressive liquids, a replacement pump can be ordered from your local Franke partner.
Which paper fits into my dispenser?
Basically the Franke paper towel dispenser are designed in a way, that the maximum possible amount of paper types can be used. Please note the maximum dimensions that fit into your dispenser. Commonly known paper product manufacturers offer a huge amount of different paper types of different quality (1 - 3 layer) and sizes. Franke recommends the Franke paper towels (EAN number 7612210000393).
Which batteries are used?
Franke recommends the use of high quality brand name batteries of the following types: Standard D 1.5 V batteries for paper towel dispensers, Alkaline AA 1.5 V batteries for soap dispensers, lithium CRP2 6 V batteries for taps.
How long is the lifespan of batteries with single products?
The lifespan of batteries is dependant on a lot of different factors. Most important is the quality of the batteries used. Tests by Franke have showed that there is a dramatic difference between brand name products and un-branded products. Brand name products had up to ten times lifespan. Another factor is the amount of usage. Less used batteries have a smaller lifespan, because of the self-discharge. Large temperature-differences and low temperatures also have a negative effect on the lifespan of the battery.
