Disinfection of already cleaned surfaces in Paris 5th
Several people use that sink. In a shared flat, treating a surface means establishing who authorises the work and when others may use it again. Disinfection applies only to surfaces already cleaned, when their condition justifies it. It never replaces cleaning. We do not add it automatically to a cleaning request.
Défi Clean assesses surface disinfection in Paris 5th flats, including homes where several occupants share a kitchen, shower room or WC. We confirm instructions, examine materials and establish conditions for reuse before agreeing a treatment. You tell us what you already know about the rooms and their ventilation, without carrying out an inspection. This page concerns disinfection; decontamination requires an identified risk assessed beforehand and has its own page.
- Treat only surfaces that have already been cleaned
- Confirm permissions for rooms used by several occupants
- Assess the material and the risk addressed
- Explain conditions before treated surfaces return to use
Plan treatment while people continue living in the flat
Clarify decisions for shared spaces
- We establish who may commission work on the surfaces concerned.
- A shared kitchen does not authorise entry into bedrooms outside the scope.
- We distinguish included fittings from neighbouring surfaces that remain excluded.
- Conditions for reuse also apply to other occupants using those fittings.
Examine the material before choosing treatment
- A laminate worktop requires attention to its finish and visible condition.
- We distinguish wall tiles from porous materials elsewhere in the room.
- Treatment of porous supports needs assessment according to the risk addressed.
- We rule out treatment incompatible with the material or its finish.
Define what happens before reuse
- We explain the applicable contact time for the surfaces being treated.
- Required ventilation depends on the treatment and the flat’s available arrangements.
- Any rinsing follows the conditions specified for the agreed surface treatment.
- We never present these operations as sterilisation of the whole flat.
Shared rooms in Sorbonne and Val-de-Grâce need clear permissions
In shared flats in the Sorbonne and Val-de-Grâce quartiers, a kitchen, shower room and WC may serve several people who do not all hold the same permissions. Before treating a sink or another shared surface, we establish who commissions the work and which rooms are included. Permission for the kitchen does not let us enter an excluded bedroom. We also agree when each treated surface may return to use, since other occupants remain in the flat. Contact time, ventilation and any rinsing determine those conditions. We do not assume immediate reuse is possible simply because someone needs the fitting. These arrangements form part of preparing the accepted work.
Plaster, painted joinery, tomettes, stone, laminate worktops and wall tiles in these old flats behave differently. We examine the material, finish and condition before proposing treatment. A windowless shower room or blocked ventilation duct also requires us to separate accessible surfaces from conditions that depend on the building. Disinfecting a wall does not repair the ventilation. You tell us only what you already know about the airflow or openings, without removing a grille or inspecting a duct. We explain which surfaces we can treat and what remains outside that operation. A clean-looking wall does not, by itself, establish that the room’s ventilation will meet the conditions required for treatment.
Assess the surfaces and organise their return to use
Initial information
You identify the surfaces already cleaned and rooms concerned, together with known shared uses and ventilation details, without dismantling a grille or inspecting hidden spaces.
Permission check
We establish who is entitled to commission the work and confirm included surfaces, without extending permission to neighbouring bedrooms, cupboards or other fittings.
Treatment assessment
We examine the material, finish and risk addressed to determine whether disinfection is justified for the particular sink, wall or worktop concerned.
Agreed conditions
We explain contact time, ventilation and any rinsing needed before reuse, accounting for the other occupants who continue to use the shared fittings.
Defined treatment
We treat only the accepted surfaces that have already been cleaned, following the agreed conditions without automatically adding rooms or working on ventilation ducts.
Use instructions
We restate the conditions for using treated surfaces and the limits related to materials, without declaring the whole flat sterilised or guaranteeing habitability.
Points to check before disinfection
- Surfaces already cleaned and the reason a further treatment is being considered.
- The person entitled to authorise work in rooms used by several occupants.
- Fittings included in the request and bedrooms remaining outside the agreed scope.
- The material, finish and visible condition of each surface proposed for treatment.
- The risk addressed and whether the operation suits the particular support.
- Ventilation arrangements already known without asking anyone to investigate inside a duct.
- Contact time and any rinsing required before the fittings return to use.
- Other occupants’ use of the sink, shower or WC during the agreed work.
Disinfection works best on non-porous materials. On a porous support, its effectiveness depends on the material, the product and the risk addressed, so assessment is necessary. We do not automatically treat stone or painted joinery like glazed wall tiles. A blocked duct remains separate from surface treatment. We promise neither the disappearance of a smell nor habitability, and disinfection never amounts to sterilising the whole flat. Any conditions for contact time, ventilation and rinsing must still be respected.

Questions about disinfection in a shared flat
Can a kitchen be disinfected before it has been cleaned?
No. Disinfection applies to surfaces already cleaned and only when their condition justifies it. It does not replace removing deposits from a sink or worktop. If cleaning remains necessary, we distinguish that preliminary operation from any surface treatment that may subsequently be considered and agreed.
Can one housemate commission treatment throughout the flat?
We check their authority for the rooms and surfaces concerned before starting. Daily use of a shared kitchen does not establish permission to commission work in every bedroom. The accepted scope identifies included fittings. We do not enter a room that remains outside that scope or assume another occupant’s agreement.
When can other occupants use treated surfaces again?
We explain the conditions before the work, including contact time, ventilation and any rinsing. Reusing a sink or worktop depends on those conditions being met. We account for shared use without promising that a fitting can be used immediately after treatment or treating convenience as a reason to shorten those requirements.
Can all the old materials receive the same disinfection?
No. Disinfection works best on non-porous materials. On porous supports, effectiveness depends on the material, product and risk addressed. We assess stone, tomettes or painted joinery together with their finish and condition, rather than automatically applying the treatment considered for glazed wall tiles elsewhere in the room.
Do I need to check the ventilation duct before contacting you?
No. Tell us only what you already know, such as a shower room having no window or a grille known to be blocked. You have nothing to dismantle or inspect. We distinguish conditions depending on the building from the surfaces we can treat within the agreed operation.
Is a smell enough to justify disinfection?
No. A smell alone does not identify its source or establish that treatment is appropriate. Disinfecting a wall does not correct faulty ventilation and does not guarantee the smell will disappear. We assess whether the operation is justified for the surfaces concerned instead of adding it automatically to the cleaning request.
Does disinfection mean the flat is sterilised and habitable?
No. It concerns the agreed surfaces and operations, rather than sterilisation of the entire flat. A wall, fitting or part of the building may have limitations separate from the treatment performed. We describe what has been done without guaranteeing habitability or presenting our visit as a complete assessment of the premises.
