Situation/Problem	Solution	Notes and comments
Routine cleaning All grades and finishes	Inox Creme applied with soft cloth or sponge. Rinsed and wiped dry.	If possible, use a warm to hand-hot solution. A 5% addition of ammonia is beneficial.
Fingerprints All finishes	Pretreat marks with alcohol or an organic solvent. Follow immediately with Routine Cleaning.	Minimise reoccurrence by applying a wax or silicone based household polish to the clean, dry surface.
Stubborn stains and discolouration - all finishes except coloured stainless steel	Use a small amount of a creamy paste of mild household abrasive cleaner on cloth wetted with detergent solution as for Routine Cleaning. Rinse and dry.	Repeat several times rather than resorting to a single aggressive cleaning method. If stubborn stains persist use a fine synthetic scourer pad instead of a cloth. Rub gently.
Lime scale deposits from hard water	Prolonged soaking in a 25% vinegar solution or a 5% nitric acid solution. Periodically rub with a nylon bristled brush or fine synthetic scourer pad.	Can usually be prevented by regular Routine Cleaning. Do not allow excessive buildup before treating.
Grease, fats and oils - all finishes	Wipe off excess with soft cloth or paper towel. Use a water borne or water soluble degreasing agent. Follow by Routine Cleaning.
Rust marks due to presence of or contact with ferrous materials	If heavy, swab with a sponge wetted with a dilute (10-15%) solution of nitric acid (HNO3). Follow by Routine Cleaning.	Avoid any contact of ferrous (iron containing) materials with stainless steel. Dilute nitric acid (HNO3), in strengths of up to 20%, is a "friendly" acid to stainless steel. It is the ONLY acid which may be used with no risk to stainless steel.
Dark oxide scale from welding or heat tints.	Pickling and passivating plus thorough water rinsing is outlined on previously. Follow by Routine Cleaning.	Slight heat tints ma be removed by repeated application as for Stubborn Stains and Discolouration.
Scratches on polished (lined) finishes	Slight scratches. Use nylon pad loaded with iron free abrasive polishing compound. Follow the direction of the original polish lines. Follow by Routine Cleaning.	Deep scratches will be difficult to remove completely. Do not use metal scourers or wire wool unless they are made from stainless steel.

Cleaning Procedure
Clean the Stainless steel as often as experience dictates (i.e. when noticeably dullor dirty); and use the simplest cleaning procedure that will effectively "do the job".

• Stainless steel's best friends are clean water or mild detergent solution, applied with a soft cloth or sponge, rinsed well and wiped dry.
• Routine simple, gentle and inexpensive cleaning will retain both the corrosion resistance and appearance of stainless steel through years of exposure and use.
  Occasionally a small amount of Inox Creme may be used on a soft cloth wetted with the detergent solution to remove stubborn dirt or slight incipient stains. Rub gently.

Cleaning Do's

• Employ regular routine cleaning rather than accasional aggressive single cleaning.
• Only use propriety brands of cleaners that state "Suitable for Stainless Steel", such as Inox Creme.
• Always rinse and dry as the final step in a cleaning procedure.

Cleaning Dont's

• Do not use coarse abrasive powders.
• Do not use metallic scourers or brushes with metal bristles.
• Do not use the so termed "silver cleaners".
• Do not us acids (except nitric acid in specific instances).
