Unidrain products are made from brushed stainless steel (AISI 304). The products should be cleaned regularly, so that both drain systems and other accessories last longer and function optimally, and the products retain their fine appearance. Unidrain's floor drains are available in two series: ClassicLine and HighLine. The parts for the two types of floor drains, fixtures, frames and gratings and panels are made from brushed stainless steel (AISI 304), and outlet units, odour barriers and water traps, etc. are made from injection-moulded plastic (polypropylene). The surface of both the HighLine Colour
and Reframe products is PVD-treated to produce the fine colours. Never spray cleaning agent directly onto the surface, as this can cause damage to the surface from the inside; always spray the cleaning agent onto a cloth or a soft sponge. Cleaning agents with a high concentration of fluorine, chlorine and hydrogen peroxide must NOT be used. Always rinse the surface carefully with water after using cleaning agents – residues from alkaline cleaning agents, in particular, can damage the surface. The surface is sensitive to greasy fingers, but it can be polished with a microfibre cleaning cloth. We recommend Unidrain's eco-friendly cleaning kit.
Stainless steel is highly durable if it is cleaned on a regular basis. The surface is covered with a thin protective layer of chromium oxide. Corrosion can occur if this protective layer is damaged, for example by impurities present in the steel itself. Strong acids or chemicals such as iodine, chlorine, fluorine or bromine can impede the oxygen reaction process, thereby removing the protective layer.
Lift the grating and remove the strainer from the drain unit. Clean all three parts using a soft cloth or soft-bristled brush lathered with mild, non-abrasive soap and lukewarm water. Do not use steel wool. Gently polish the grating and drain in the same direction as the brushed grain. The grating can also be treated for lime deposits using ordinary descaling agents. Always follow the directions on the product label.
Disassemble the top and bottom components of the water trap by pulling them apart. Rinse the two components under warm running water. You may use soap, descaling agent and a nylon scouring pad if these are suitable for household use. Always follow the directions on the product label.
If the floor drain has been cleaned and water is still not flowing freely through the system, or an unpleasant odour is emanating from the drain, this it is a sign that the water trap has not been correctly reassembled. This occurs because the top component has been pressed down too hard, or because the water trap is not in the correct position. Remove the water trap and check that the components have been correctly reassembled with a distance of around one finger’s breadth between the top and bottom components. Push the water trap back into position at the bottom of the outlet unit.
