Each of the steps linked to maintenance has risks of deteriorating the passive layer: using hard water / overdosing cleaning
products / use of chlorinated detergents / food residue on the products / insufficient rinsing...
For any case of corrosion, the element or the step that is the source of this must be identified.
Recommendations :
- keep stainless steel surfaces clean and dry. Allow the air to circulate.
- clean on a daily basis to remove tarter, grease and all food residue. Corrosion can form under these layers due to a
lack of air.
- daily cleaning can be done with a wet cloth. If necessary:
* use soapy water, cleaning products with low chloride content, non-bleach detergents, degreasers for windows.
* remove difficult grime with a non-metal brush (plastic material, natural silk or stainless steel wool).
- do not scratch the surfaces with metals other than stainless steel. In particular, do not use iron brushes.
- fresh rust stains can be removed with gentle abrasive agents or with a fine grade of emery cloth.
- for larger stains, use hot oxalic acid at a concentration of 2-3%. If necessary, treat with nitric acid at a concentration of
10%.
After any treatment, wash with plenty of water and wipe. The use of acid is reserved for those trained and in compliance
with regulations.
Products to be avoided :
- bleach and chlorine derivatives
- hydrochloric acid
- abrasive powders with iron oxide.
y Plastic and stratified parts: do not use ethyl alcohol, wine derivatives, bleach, pure, petrol, vinegar, sulphuric, nitric or
hydrochloric acid, etc...
