Spraying appliances or parts of appliances with a water jet or high pressure cleaning equipment is harmful and can cause malfunction. This is therefore prohibited. Note: The type and concentration of solvents used for cleaning the surfaces must comply with the code of the Federal Regulations 21 CFR Part 178.1010. 8. TREATMENT OF COMMERCIAL KITCHEN APPLIANCES Commercial kitchen appliances are executed in corrosion resistant chrome nickel steels, material numbers 1.4301 and 1.4404. The corrosion resistance of these steels is based on a passive layer formed on the surface with access to atmospheric oxygen. Accelerated formation or reformation of the passivity occurs by treating surfaces with running water containing oxygen. Aggressive media with a reducing effect (oxygen consuming) such as substances containing hydrochloric acid, chlorides and seasoning concentrates, mustard, vinegar essence, seasoning or spice tablets, salt solutions, etc., depending on concentration and temperature, can result in chemical damage or the destruction of the passive layer. Damage can also result from foreign rust (iron particles) due to the formation of galvanic elements and lack of oxygen (no air access or low oxygen water). Therefore the following principles should be observed when working with high grade steel equipment: 1. Surfaces of equipment of corrosion resistant steel are always to be kept clean and exposed to the air. Remove covers from utensils when not in use to provide free air access. Regularly remove limescale, grease, starch and egg white deposits by cleaning. Corrosion can occur under these layers due to the absence of air exposure. Limescale can be removed with 10% acetic acid, 10% phosphoric acid or with suitable limescale removers available on the market. 2. Corrosion resistant steel objects must not be kept in longterm contact with acids, spices and seasonings, salt, etc. Also promoters of corrosion are acid vapours as produced during floor cleaning. Contact surfaces are to be rinsed off with fresh water. This applies after use, especially after cooking potatoes, noodles, rice etc. in salt water. Dried-on cooking water residues form high concentration salt solutions which can cause point corrosion. So, immediately after use, rinse cooking utensils in fresh water or keep filled with cold water to cool them. It is not advisable to use one utensil exclusively for cooking e.g. potatoes in salt water. For stainless steel it is beneficial to use utensils for different produce, e.g. for soups containing fat or acid-containing vegetables (such as sauerkraut, for example). 3. Stainless steel surfaces should, where possible, be protected from mechanical damage, especially from other metals. Corrosion can occur if stainless steel comes into contact with iron (steel wool, chips from pipes, water containing iron). New corrosion locations can be removed with a mild abrasive or fine emery cloth. Heavier corrosion can be washed off with a warm 2-5% solution of oxalic acid. Treatment with 10% nitric acid is necessary if this proves ineffectual. Due to the associated hazards, this type of cleaning is only to be carried out by suitably trained staff in compliance with the valid regulations. 4. No bleaching or chlorine-containing cleaning agents are to be used for cleaning. Utensils are to be thoroughly rinsed with water and dried after cleaning. The surfaces of appliances are of corrosion resistant chrome nickel steel. They are to be washed down with hot soapy water with the addition of a standard grease solvent.
