General Maintenance
All canopy and grease filter assembly surfaces should be cleaned on a weekly basis to prevent build-up of grease within the system and maintain the appearance of the canopies etc.
The attractive and hygienic surface appearance of stainless-steel products cannot be regarded as completely maintenance free. All grades and finishes of stainless steel may in fact stain, discolour or attain an adhering layer of grime in normal service. To achieve maximum corrosion resistance the surface of the stainless steel must be kept clean. Provided that cleaning schedules are carried out regularly, superior performance and long life will be achieved. Surface contamination and the formation of deposits are critical factors which may lead to drastically reduced life. Commercial and even domestic and naturally occurring atmospheric conditions can result in deposits which can be quite corrosive. Working environments can also create more aggressive conditions, such as the warm, high humidity atmosphere above combination and steaming ovens. These environments can increase the speed of corrosion and therefore require more frequent maintenance. Cleaning solutions often contain sterilisers and bleaches for hygienic purposes. All these proprietary solutions, when used in accordance with the manufacturers ‘instructions' are safe, however, if used incorrectly (e.g., warm, or concentrated) can cause discolouration and corrosion on the surface of stainless steels. Strong acid solutions (e.g., hydrochloric acid or "spirits of salts") 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 by copious water flushing.
Stainless steel is easy to clean. Washing with soap or a mild detergent and warm water followed by a clean water rinse is usually quite adequate. An enhanced appearance will be achieved if the cleaned surface is finally wiped dry.
All maintenance work is to be carried out safely (fully in accordance with all relevant method statements / risk and COSHH assessments) by competent, trained personnel provided with all relevant PPE and Access equipment necessary to carry out the works in accordance with safe working practices.
All fans and electrical equipment are to be isolated prior to any works being carried out on the systems.
