These are two different jobs. Doing one does not cover the other, and doing them in the wrong order wastes both.
You wipe the board with a cloth. The crumbs are gone and the surface looks spotless. So it is ready for the next job, isn't it?
Looking clean and being safe are two different things.
Stage 1A dirty surface
Food residue, grease and bacteria. The debris you can see, the bacteria you cannot.
Order matters
Disinfectant cannot get through dirt
Disinfectant on a dirty surface
The disinfectant lands on the dirt and never reaches the bacteria. It is close to wasted.
Clean first, then disinfect
With the residue gone, the disinfectant makes contact and does the job it was bought for.
Clean first. Then disinfect. Doing it the other way round means you paid for a chemical that never touched a single bacterium.
Doing it
Clean it down
Straight after raw chicken. Food residue and grease you can see, bacteria you cannot.
Five actions, listed in no particular order. Tap them in the order you would really do them.
Your turn
What would you do?
You finish prepping raw chicken on a stainless bench. You spray sanitiser straight over the surface, wipe it off immediately with a cloth, and start assembling sandwiches on the same bench.

Contact time
Disinfectant needs time on the surface to work
Spray and wipe straight offRemoved before it worked
Spray, leave for the contact time, then wipeBacteria reduced
The contact time is printed on the product and it varies, from around 30 seconds to several minutes. Spray it, leave it, then wipe. A surface that gets sprayed and immediately dried has been decorated, not disinfected.
Clean as you go
Deal with it now, not at the end of the shift
Faster
A surface sorted right after use takes seconds. The same surface after ten hours is a real job.
Safer
Bacteria and allergens are not left building up on surfaces through the whole shift.
Less cross-contamination
Every job starts on a surface that the previous job did not contaminate.
In production the same idea is formalised as a cleaning schedule, with named tasks, frequencies, and a signature against each one.
The five things to remember
1Cleaning removes dirt and food residue. Disinfection reduces bacteria to a safe level
2Both jobs are needed. Doing one does not cover the other
3Clean before you disinfect, because residue stops disinfectant working
4Give disinfectant its contact time before wiping it off
5Clean as you go instead of leaving it all to the end of the shift
