Is it clean ?
Technical clean

Perceived/looks clean

State of maintenance

If it looks clean, it can be technical dirty. If it is technical clean, it still
can be perceived as dirty. The state of the maintenance has a big
influence!
Secrets to increase
perceived cleanliness
• Spray a scent (eg. lemon)
• Attention for shiny surfaces: bling bling 
• Align everything, put things in corners of 90° or
parallel
Why do more than needed?
• There is more than costs – happy guests return 
• You invest time (do more than expected - eg. a 4h
clean) trying to give the WOW-effect to the guest
• Once you’ve done a 4h (or 8h) clean well, the 2h
cleans will be faster and there is more tolerance
when you have to do a 1h clean
More theory
Sorry, in Dutch
Cleaning errors
• De (laatste) reiniging is niet of niet
helemaal uitgevoerd.
• Meerdere reinigingscycli zijn niet of
niet helemaal uitgevoerd: cumulatieve
vervuiling.
• Er is wel schoongemaakt, maar niet op
de juiste manier : method error
• Niet schoon te maken : materiaalfout
http://www.vsr-org.nl/images/stories/Onderzoek/Beoordelen_van_vervuiling.pdf
http://www.schoonmaakkwaliteit.nl/images/stories/Brochure_VSR-KMS_2.0.pdf
Standards
• European standard EN 13549 Cleaning
services - Basic requirements and
recommendations for quality
measuring systems
• In Nederland beschikken we over de
norm NEN 2075 –
Kwaliteitscontrolesysteem voor
Schoonmaakdienstverlening.
NEN 2075
• Norm document van het VSR-Kwaliteitsmeetsysteem (VSR-KMS).
• Deze norm bepaalt: beoordelingsvoorwaarden, keuringscriteria,
inventarisatie van een gebouw, bepaling van een steekproef,
controle, goedkeurgrens en bevat een beoordelingshandleiding van
meest voorkomende elementen, tabellen voor AQL waarden
– 7% (kantoren),
– 4%(sanitair)
– 3% (gezondheidszorg).

• De norm NEN 2075 is gelijk aan het VSR-Kwaliteitsmeetsysteem, in
de wandelgangen meestal VSR-meetsysteem of KMS genoemd. Dit
systeem omvat in het kort twee zaken:
– Een manier om objectief het resultaat van schoonmaken visueel te
beoordelen, dus schoon of niet schoon.
– Een manier om met behulp van een steekproef een geheel gebouw op
schoonmaak resultaat te controleren, met als doel controle tijd te sparen
en controle kwaliteit te handhaven.

http://www.vsr-org.nl/images/stories/Praktijkrichtlijnen_VSR-PR_1-2.pdf
Oppervlakte reinheidsklassen
• Klasse A : visueel gemeten schoon
• Klasse B : biologische schoon
• Klasse C : visueel schoon
• Klasse D : functioneel schoon
• Klasse E : machinaal schoon
• Klasse F : bezem schoon (vrij van
zichtbaar los grof (> 1cm2) vuil)
• Klasse G : bulldozer schoon
http://www.vsr-org.nl/images/stories/Praktijkrichtlijnen_VSR-PR_1-2.pdf
Termen
• Accepted Quality Limit (AQL).
• Maximale aantal foutmogelijkheden
(MAF-waarde)
What is the limit ?
• The ACC (total aerobic colony count)
from a hand contact surface should be
< 5 cfu/cm2
• Other studies have associated ACC
levels >10 cfu/cm2 with poor hygiene.
