USEFUL HINTS OF STAINLESS STEEL MAINTENANCE 

Stainless steel is so called because it is not affected by oxidation,this is due to a  thin molecular layer of 
oxide on the surface which protects againts further oxidation. There are, howevwr, substances which can 
modify or destroy this layer,giving rise to corrosion:besides preventing the protective film of oxide from 
reforming,these substances corrode the stainless steel itself and can cause irreparable damage. It is 
therefore necessary to prevent this by choosing correct cleaning products and by complying with the 
following simple recommendations:

never forget that when using these appliances,the first and 

fundamental rule is to guarantee that the cleaning products are both non-toxic and hygienic.

 
Before using any detergent to clean either the stainless steel or the immediate and sorrounding floor area, 
always ask your supplier for the most suitable product which does not cause corrosion on the steel itself; the 
onset of rust is most commonly caused by the use of unsuitable cleaning  materials (strongly acid chlorate 
based detergents) or on inadequate maintenance. 
 
Our appliances are made of stainless steel AISI 304 for exterior panelling,upper tops,tanks etc. 
Comply with the following instructions when cleaning and servicing parts in stainless steel. 
 

Ordinary daily maintenance 

Carefully and frequently clean the surfaces using a damp cloth; use soap and water or normal detergents,

so 

long as these do not contain abrasives or chlorine based substances 

such as sodium hypochlorite 

(bleech),hydrochloric acid or other such solutions:These products quickly and irreparably corrode stainless 
steel. When cleaning floors underneath or near the appliances, never use the above mentioned products as 
vapours or splashes could subject the steel to similar destructive effects. 
Only ever rub in the direction of the satining, then thoroughly rinse with clean water and carefully dry. 
 

Rust :

 water supply pipes, inevitably convey particles of rust dissolved in the water especially in new 

installation plants or when taps are opened after a period of inactivity. These iron deposits must not be 
allowed to remain on the stainless steel since they produce rust by contamination. 
Use suitable products to remove any rust marks,from companies which produce detergents for industrial 
use. After application, thoroughly rinse with clean water, neutralizing the action of the product with an 
alkaline detergent normally used to clean such appliances or with another specific product. 

 
DO NOT USE METAL MATS TO CLEAN THE STAINLESS STEEL
