7 Cleaning and Care
NOTE Cleaning in the washing device
The appliances in the ISOBOX® Mobil Basic model range can be cleaned in
an automated cleaning system.
7.1Hygiene Measures
It is essential for operating staff to act in the correct manner to ensure optimal hygiene.
All persons must have sufficient knowledge about the locally valid hygiene regulations, observe them and
comply with them.
Use a waterproof plaster to cover wounds on hands and arms.
Never sneeze or cough on clean crockery or meals.
7.2 Cleaning and Care
If the appliance is handled with care, cleaned and maintained on a regular basis, it does not require any ad-
ditional care measures. The boxes should be cleaned regularly after every use to ensure a perfectly hygienic
operation.
For quick and thorough cleaning, wipe the inside of the boxes with a soft cloth. Use a soft cleaning cloth or
an uncoated sponge for cleaning. Use degreasing liquid cleansers that are approved for the food industry.
Never use high-pressure cleaners, chloride-based cleaning agents, abrasive cleaning powder or other dry
cleaning agents, steel wool, steel sponges and/or sharp-edged items.
7.3 Special Care Instructions for Aluminium Surfaces
Pure aluminium reacts slightly to oxygen in the air. A thin, natural layer of oxide forms on the metal surface
due to this reaction between oxygen and aluminium. This uniform oxide layer provides the material with ex-
cellent corrosion protection as it becomes chemically inert.
However, acids and alkalis attack the oxide layer or dissolve it, meaning that the corrosion protection may be
lost. Depending on surface requirements and exposure to stress, further measures such as anodisation or
powder coating are necessary to produce corrosion-resistant, wear-proof aluminium surfaces.
Important instructions for aluminium surface care:
§It is best to use clean water, possibly adding a little pH-neutral cleaning agent, and soft, non-scouring
cloths to clean aluminium.
§Do not damage surfaces. Do not use highly abrasive cleaning materials. Do not use any steel tools as
they may scratch the surface. Abrasive cleaning agents or accessories, such as scouring agents,
steel wool or scouring pads, may damage aluminium surfaces and should not be used.
§Do not treat surfaces with strongly acidic (pH value less than 5) or strongly alkaline (pH value more
than 8.5).
§Wipe with clean water to finish, so that no residues are left on the surface.
§As a basic rule, you should check whether a cleaning agent can be used by trying it out on a non-
visible section or on a sample surface first.
Suitable cleaning agents for cleaning aluminium surfaces:
§Use neutral cleaning agents, such as water with washing-up liquid, to clean off easy-to-remove stains
from coated surfaces.
§Use slightly acidic cleaning agents, such as vinegar and water in equal parts, to remove tougher
stains.
§Remove strong coats of grease with organic solvents, such as ethanol. Keep the exposure time to a
minimum. Rubbing may cause the coating to lose its glossy appearance.

Cleaning anodised aluminium surfaces:
§Carry out care tasks on surfaces on a regular basis by washing with clean water and washing-up liq-
uid and then rinsing. After drying, apply an anodising cleaner sparingly with a soft cloth. Then polish
with a dry, soft cloth to achieve a streak-free surface.
§To remove tough stains, apply anodising cleaner on a cloth and rub briskly onto the surface. Then
polish with a dry, soft cloth.
§There are special anodising touch-up applicators or sprays available from specialist retailers.
Cleaning powder-coated aluminium surfaces:
§Carry out care tasks on surfaces on a regular basis by washing with clean water and washing-up liq-
uid, rinsing and rub with a chamois leather. You can also treat with a suitable polish to preserve the
surface.
§You can also use a suitable abrasive cleaning agent to remove heavier stains after cleaning.
There are special touch-up applicators or sprays available from specialist retailers.
7.4 Special Care Instructions for Stainless Steel
Resistance to corrosion in stainless steel is provided by a passive layer which is formed on the surface when
oxygen is absorbed. The oxygen in air is sufficient to form the passive layer, so that damage caused by
physical action is eliminated automatically.
The passive layer develops or is renewed more quickly when the steel comes into contact with water containing
oxygen. The passive layer can be chemically damaged or breached by agents which have a reducing (oxygen-
consuming) effect when they come into contact with steel at concentrated levels or at high temperatures.
Such aggressive substances include:
§substances containing salt and sulphur
§chlorides (salts)
§seasoning concentrates (e.g. mustard, vinegar essence, seasoning cubes, saline solutions).
Further damages can occur due to:
§extraneous rust (e.g. from other components, tools or rust film)
§iron particles (e.g. grinding dust)
§contact with non-ferrous metals (element formation)
§lack of oxygen (e.g. no admission of air, low-oxygen water).
General working principles for handling appliances made of "refined stainless steel":
§Always keep the surface of appliances made from stainless steel clean and open to air.
§Use cleaning agents suitable for stainless steel. Never use bleaching cleaning agents or any contain-
ing chlorides.
§Remove layers of lime scale, grease, starch and egg-white by cleaning daily. Corrosion may occur
underneath these layers due to lack of air absorption.
§After each cleaning operation remove all cleaning agent residues by wiping thoroughly. The surface
should be thoroughly dried after wiping.
§Do not bring items made of stainless steel into contact with substances such as concentrated acids,
seasonings and salts for longer than is absolutely necessary. Acid fumes emitted when tiles are
cleaned also cause corrosion in "refined stainless steel".
§Avoid damaging the surface of the stainless steel, especially by bringing into contact with metals oth-
er than stainless steel.
§Residues from other metals produce extremely small amounts of chemical elements which can cause
corrosion. Contact with iron and steel must be avoided at all costs, because it will cause extraneous
rust. If stainless steel comes into contact with iron (steel wool, steel particles from pipes, water con-
taining iron), this can trigger corrosion. Therefore, only use refined steel wool or brushes with natural,
plastics or refined steel bristles only for physical cleaning. Steel wool or brushes with unalloyed steel
cause extraneous rust due to abrasion.
