MAINTENANCE
CLEANING AND PROTECTION
One of the last stages of maintenance is the application of protective agents.
From the moment they are installed, all pieces of equipment are continuously exposed to oxidising agents and
moisture in the air. It should be noted that the metal parts of the machine will also benet from the use of a protective
product as they are also affected by the adverse conditions in which they work.
In cold dry weather, corrosion rates are lower than in warm conditions, but in a marine climate -with heat and
moisture- corrosion rates are much higher although considerable local variations might exist. Protection will largely
depend on air corrosiveness and should be adjusted to each specic situation.
Some cleaning and preservation instructions are given next:
• CLEANING:
Products to be used: Aluminium and stainless steel cleaner “CLEAN MACHINERY”.
Reference Volume
5288301 1 L.
5288310 10 L.
5288320 20 L.
Cleaning frequencies will depend on dirt levels. A monthly cleaning is generally recommended.
The product is applied as follows:
1) Spray the recommended product directly on metal surfaces. The product must be applied as described in the
technical data sheet and the product label.
2) Let the product work on the surface for two minutes and then wipe it with a cloth or a soft brush for the desired
nish.
• PROTECTION:
Products to be used: ISTOBAL stainless steel protector ‘CLEAN INOX’.
Reference Volume
5305101 1 L.
5305110 10 L.
5305120 20 L.
The next table shows maintenance intervals for different air corrosiveness categories:
Air corrosiveness categories:
(Classied as per ISO 12944)
Stainless steel protector
Frequency
C1 Very low Monthly
C2 Low Monthly
C3 Average Fortnightly
C4 High Fortnightly
C5-I Very high (industrial) Weekly
C5-M Very high (marine) * Weekly
* Inhibitors may be needed to control the facility's air conditions. Humidity and temperature control is recommended,
as well as adequate ventilation.
The product is applied as follows:
1) Spray the recommended product directly on metal surfaces. The product must be applied as described in the
technical data sheet and the product label.
2) Let the product work on the surface for one minute and then wipe it with a cotton or cellulose cloth. For a more
homogeneous and even nish, always apply and rub in the same direction.
