Not all professional premises are subject to regulatory procedures that impose a high level of cleanliness, as professional kitchens, for example, may be. However, dirt develops there as on all surfaces. They must therefore also be regularly maintained to guarantee general hygiene.

Best practices for cleaning a wall

The walls are cleaned from top to bottom, starting from the dirtiest area to go to the least dirty area and avoiding going over the treated areas.

• Use the method of 8 or parallel strips by proceeding back and forth, to cover the entire surface.
• Use protective rubber gloves.   
• Important: when it is not useful to reduce the presence of microorganisms as much as possible, disinfectant products are not necessary.

The steps to wash an interior wall like a pro

First step: dusting the wall or ceiling

1. Dust the wall using a professional vacuum cleaner (preferably with a HEPA filter to retain residual particles) equipped with a perfectly cleaned parquet brush.
2. Complete with a feather duster to remove dust from fragile areas (baseboards, moldings, switch surround, wall hanging system, etc.). You can also use a flat mop, a damp microfiber and a bi-bin bucket to separate dirty and clean water.
3. Finish with a wolf’s head broom to dislodge cobwebs in corners and hard-to-reach places.

If the wall is painted and washable, the choice of professional cleaning and degreasing products depends on the type of paint applied:

1. Adapt the cleaning product to the type of paint:
   
   Acrylic or casein paint: Warm soapy water. Marseille soap is very effective
   
   Vinyl glycerine paint: A mixture of hot soapy water and washing-up or washing-up liquid.
2. Use a grease removal agent on the walls with a non-abrasive heavy-duty sponge (never use a scraper as you risk scratching or damaging the surface). If the wall is very dirty, repeat the operation as many times as necessary.
3. Perform a final rinse with clear water
4. Dry with a clean, dry microfiber to remove all the moisture on the wall and avoid rings of cleanliness.
