3.1.1 Rust on industrial dishwashers
• Large-scale industrial dishwashers in general as well as our dishwashers
are made of stainless materials, but despite this, there are still situations
where rust can occur on “stainless” materials.
• We are going to describe a few reasons for this here, so that you, as a user,
service engineer or other type of personnel, can avoid this.
• Rust usually occurs due to the fact that something that is not stainless finds
its way onto the stainless surface. The non-stainless particles will soon
start to rust, and then contaminate the stainless material, which also starts
to rust. If no action is taken at this point, serious damage such as a hole in
the material can occur.
N.B.! If rust spots have developed, they must be dealt with immediately by a per-
son authorised to do so!
RISK SITUATION CAUSE DECLARATION / ACTION
Drilling holes when installing a
detergent device.
Using a drill or hole saw that has pre-
viously been used for ordinary non-
stainless materials.
“Contaminated” hole-drilling tools
can cause enormous damage in the
form of pores in stainless plates.
Never use a cutting tool that has pre-
viously been used on other materials
or blackplate.
Using blunt tools when drilling holes. Stainless plate, which has overheat-
ed during hole drilling, may lose its
“stainless” properties.
This can show up as rust around the
hole for the detergent cell.
Shavings from hole drilling. The shavings from drilling or hole
sawing are usually heated so much
that they lose their stainless proper-
ties.
They must always be removed by
hand! Washing after hole drilling is
not enough!
Rust spots that occur during nor-
mal operation and use.
Minerals, e.g. ferrous gravel or
earth, from dishware or food (vege-
tables and root vegetables) that has
been lying in crates, find their way
onto the stainless surface. Minerals
(gravel) can also be found on the
wheels of catering trolleys.
Daily cleaning is always important.
Use a suitable brush for “mechani-
cal” cleaning, e.g. in the wash tanks,
on the wash trays and filters.
Steel wool. Ordinary steel wool is not
stainless, and can cause serious
damage to stainless surfaces and
plates.
Use stainless cleaning pads Re-
move all ordinary steel wool from the
catering facility / restaurant.
