APPLIANCE ROUTINE MAINTENANCE / CLEANING

ROUTINE MAINTENANCE

Safely disconnect the appliance from the 

power supply before cleaning, servicing or 

undertaking general maintenance.

We recommend that you undertake regular 

preventative maintenance using a qualified 

 

service provider in order to get the best from  

your equipment.

CLEANING

 

Always wear appropriate personal protective 

equipment (PPE) when cleaning the appliance. Care 

should be taken for parts with possible sharp edges. 
Stainless steel is naturally corrosion-proof and 

needs no additional protective coating to maintain 

its gloss and usability for a long time. 
Abrasive or corrosive cleaning agents should never 

be used. These can damage surfaces and cause 

corrosion. They include: 
• 

Cleaners containing chloride; 

• 

Bleaches containing hypochlorite (if accidentally 

spilled on stainless steel, rinse off with water 

immediately and thoroughly); 

• 

Silver polish 

If the cabinet exterior is looked after correctly it will 

retain an “as new” finish for many years. A damp 

cloth is usually sufficient for wiping away light dirt 

and finger marks and normal day to day cleaning 

should be carried out with a soft cloth and soapy 

water. 
Dry thoroughly afterwards and where possible 

remove all racking and shelving fittings to aid the 

process. 
For stainless steel with visible polishing grains, clean 

the steel with the grain - not against the grain. When 

water has been used for cleaning or rinsing, wipe 

the surface dry to prevent water from drying and 

forming watermarks, especially in areas with hard 

water. Avoid this type of watermark by using distilled 

water. 
For tougher spots, creamy polishes like CIF original 

cream can be effective. Light pressure should be 

used when cleaning with the grain. The cleaning 

process should be repeated in order to prevent any 

dirt becoming lodged in the surface grain again. 

CIF original cream cleaner can also be used 

for wiping off water spots and can alleviate 

discoloration. Remove this type of residue by rinsing 

with clean, preferably distilled water and wipe away 

any remaining streaks of polish or watermarks. 
Tough grease or oil marks can also be removed 

using denatured alcohol or acetone. There is no risk 

of corroding stainless steel by using such solvents. 

For ease of use limit the amount of solvent used. 

Wash more than once using a pure solvent on a 

clean soft rag until all traces of the greasy residue 

are removed. 

Specialist Stainless Steel Cleaners 

 

Innosoft B570 is a special deep cleaner that is 

suitable for the intensive cleaning of contaminated 

stainless steel surfaces, and removes stains and 

oxides in a single operation. 
Innoclean B580 completely removes any residues 

left after the use of Innosoft B570 and passivates 

the surface which helps to prevent further 

corrosion.
With regards to the above recommended cleaners, 

always check that they will not have any detrimental 

effect to the stored contents.

SHELF / SUPPORT/ RACKING REMOVAL 

First remove the shelves, then remove the shelf 

supports by grasping firmly in the centre and lifting 

slightly. Turn the shelf support towards the interior 

of the cabinet by pushing it in the centre as you 

twist the support through 90°. The shelf support 

will be released. (NB: the supports are designed 

to be anti-tilt and you may therefore experience 

some resistance at first which will be overcome with 

practice). When all shelves have been removed, 

remove the racking by lifting up and over the nylon 

retaining blocks.
