Silicone Hose and Outlet
If left for a sustained period of time the hand sanitiser gel can start to congeal in the hoses and around the
stainless steel outlet. Regular cleaning of these components will help improve performance. To do this simply
disconnect the hoses and clean through with warm water. The outlet can be easily cleaned in situ.
Care and Maintenance of Stainless Steel
Introduction
All grades of stainless steel will stain and discolour due to surface deposits and can never be accepted as
completely maintenance free. In order to achieve maximum corrosion resistance the surface of the stainless
steel must be kept clean. Provided the grade of stainless steel and the surface finish are correctly selected,
and cleaning schedules carried out on a regular basis, good performance and long service life are assured.
Factors Affecting Maintenance
Surface contamination and the formation of deposits must be prevented. These deposits may be minute
particles of iron or rust from other sources used on the building of new premises and not removed until after
the stainless steel items have been fixed. Industrial and even naturally occurring atmospheric conditions can
produce deposits which can be equally corrosive, e.g. salt deposits from marine conditions.
The working environment also offers more aggressive conditions e.g. hot humidity, such as in a swimming pool,
increases the speed of discolouration and therefore requires the maintenance to be on a more frequent basis.
Modern processes use many cleaners, sterilizers and bleaches for hygienic purposes. All these proprietary
solutions, when used in accordance with makers instructions are safe but if used incorrectly (e.g. warm or
concentrated) can cause discolouration and corrosion on the surface of any quality of stainless steel. Strong
acid solutions are sometimes used to clean masonry and tiling of buildings, but they should never be permitted
to come into contact with metals, including stainless steel. If this should happen the acid solution must be
removed immediately and copious applications of water.
Maintenance Programme
With care taken during fabrication and installation, cleaning before handling over to the Client should
present no special problems, although more attention than normal may be required if the installation period
has been prolonged. Where surface contamination is suspected, immediate attention to cleaning after site
fixing will encourage a trouble-free product. Food handling, pharmaceutical, aerospace and certain nuclear
applications require extremely high levels of cleanliness applicable to each industry.
Advice is often sought concerning the frequency of cleaning stainless steel and the answer is quite simple
“clean the metal when it is dirty in order to restore its original appearance”. This may vary from once to four
times a year for external applications or it may be once a day for an item in hygienic or aggressive situations.
Frequency and cost of cleaning is lower with stainless steel than with many other materials and will often
outweigh the initial higher cost of this superior product.
