Maintenance of Stainless Steel
Stainless steel depends on its passive layer for its corrosion resistance. This is a very thin chromium oxide layer formed on its surface when chromium is present at 10.5% or above. The underlying metal is not corrosion resistant. The passive layer forms spontaneously on a clean surface but can be damaged by iron contamination, airborne particles and particularly chlorides.
Therefore it is imperative that stainless steel is subject to an ongoing maintenance and cleaning program. Remember it is stainLESS, not stainFREE.
Dio-Met recommend a routine cleaning programme for stainless steel every month however some harsh environments would require more regular cleaning such as coastal / high salt areas.
1. Water and a cloth.
Routine cleaning can be accomplished by using warm water and a cloth. This is the least risky option for cleaning stainless steel handrails. Dry with a towel or cloth to prevent water spots. Wipe in the directions of the polish lines.
2. Mild detergent, (dish washing liquid) and cloth.
If the stainless steel handrail exhibits staining or contamination marks, or has not been cleaned for a long time or for cleaning that needs more power: mild detergent and warm water can do a great job without damaging the stainless steel. Make sure you rinse the surface thoroughly to prevent staining and spotting. Dry using a towel to prevent water spots which can be caused by minerals such as calcium in water (hard water).
3. Glass cleaner for fingerprints.
Fingerprints are one of the biggest complaints about stainless steel handrails and parts, but can be taken care of by using glass cleaner. Rinse thoroughly and towel dry. There are some newer types of finishes for stainless steel that resist fingerprints.
4. Stainless Steel Cleaner.
If the handrails have staining or scratching, or you need to polish your stainless steel balustrade, a stainless steel cleaner may be a good option. Some of these cleaners and polishes can help minimize scratching and remove stains. They also can polish stainless steel surfaces nicely. Read the directions on the stainless steel cleaner and test in an inconspicuous spot. Be sure to rinse thoroughly and towel dry.
Maintenance of Galvanising to Steelwork
The Galvanized finish is maintenance free; only requiring cleaning if soiled, this can be done by using a cloth and a detergent in water.
Should the galvanize be damaged, then the affected area should be wire brushed thoroughly and a zinc rich paint applied (three coats).
Maintenance of Powder Coating to Steelwork
1. Water and a cloth.
Routine cleaning can be accomplished by using warm water and a cloth, Dry with a towel or cloth to prevent water spots.
2. Repair of Finish
Should the Powder coat finish be damaged then it can be repaired by lightly sanding the
affected area, Primer paint with a propriety grey acrylic primer. If the area is chipped then a two pack epoxy filler can be used (again sand back and prime).
Using an acrylic aerosol spray the affected area can be sprayed to restore the original colour.
Blend in by buffing with ‘T’ cut and final polish with a proprietary car wax
Maintenance of Glass
The glass requires no maintenance other than general cleaning
Using a proprietary glass cleaner always follow the manufacturers instructions. USE NO ABRASIVES
