Elementry Cleaning Procedure for Shower Channels

  • Remove the grate
  • Clean the channel recess using a soft cloth & warm soapy water
  • When a removable siphon is fitted (such as those using the Multi trap system), you can also :
  • remove the components and clean them using soft cloth & warm soapy water
  • while removed, you also have open access to the trap body, & the connecting pipework, for cleaning
  • Replace components in the reverse order to how they were removed
  • Also refer to the Care & Maintenance Instructions for Stainless Steel

Care & Maintenance of Stainless Steel

What is stainless steel?

“Stainless steel” (sometimes known as “inox”) is the common name for what is more accurately called “rust-free steel”. The main difference between stainless steel and other types of steel are: stainless steel is extremely durable; it is very hard; and it is much more difficult to work than other types. Stainless steel is a combination (alloy) of 80% iron with additives such as chrome, nickel, molybdenum and carbon, all of which ensure that stainless steel has a surface that does not rust.

Types of stainless steel

There are a number of types of stainless steel. The best known and most used are types 304 and 316. The main difference between the two is that type 316 is resistant to chlorine. Unlike most drains, ours are made from stainless steel 316, as it is more suitable to sea air, & common cleaning chemicals

Surface finish

The steel has two types of surface finish: brushed or polished. The standard supplied has a brushed surface finish. The brushing is done by sandblasting, which leaves uniform clear ‘scratches’ in the surface. The polished steel has a mirror-like surface and is more susceptible to scratching.

Maintenance of stainless steel

In daily use the brushed stainless steel becomes dirty through contact with greasy fingers or because of chalky deposits (scale). It can be cleaned with a solution of two measures of ammonia in a bucket of water. The surface should be brushed clean with a soft brush. Then the surface should be sprayed with a stainless steel cleanser, rubbed with a soft cloth and subsequently wiped dry. This applies a thin protective covering to the surface.

Removing stains

If you have to remove stains, we recommend that you clean the surface of the stainless steel with tepid water and a soft brush. If the stain proves stubborn, you can use an abrasive cleanser on polished stainless steel. Apply the cleanser to the surface with a soft damp cloth and rub in the direction of the grain or surface finish. Then rinse it thoroughly with water. Never use an abrasive cleanser on a grid made of polished steel.

Repairing damage / scratches

If there are small scratches or slight damage visible on the surface, this can be repaired. Clean the surface with water and a soft brush. Then spray stainless steel cleaner onto the surface and use an abrasive pad (e.g. Scotch Brite) and a cork sanding block to work the surface in the direction of the grain. Treat the surface with stainless steel cleanser, wipe with a soft cloth and then wipe dry.

Traces of “rust” on stainless steel

If rusty stains appear on the stainless steel, the rust does not come from the stainless steel itself but from something else. Some causes can be:

  • The water contains iron
  • A ferrous deposit (e.g from grinding or polishing steel)is on the surface, & that is rusting
  • There is rusty material in the immediate vicinity.
