Communal garage cleaning: how often and how it's done

The garage is one of the most neglected areas in residential community cleaning, yet it is one of the areas that accumulates the most dirt. Oil stains, dust, mud residue and vehicle exhaust fumes build up until it becomes a dirty and even dangerous space.

How often should a communal garage be cleaned?

The ideal frequency depends on size and usage, but as a general reference, a weekly or fortnightly sweep of traffic areas is recommended, along with a monthly wash of the entire surface and a thorough deep clean every quarter or six months that includes degreasing, walls and ceilings.

In garages with heavy traffic or during rainy seasons, it is advisable to increase sweeping frequency to prevent mud and water accumulations that can cause slips.

How professional garage cleaning is done

A professional garage cleaning service follows a structured process. First, a mechanical sweep is carried out with an industrial sweeper to remove dust, sand and solid waste. Next, a specific degreaser is applied to oil stains and left to act for several minutes.

The entire surface is then washed with an automatic scrubber or pressure washer, depending on the floor type. Access ramps require special attention as they accumulate dirt dragged in from outside. Finally, walls at accessible height, pillars and signage are cleaned.

Oil stains: the most common problem

Oil stains are the biggest enemy of garages. If not treated in time, they penetrate the concrete and become virtually impossible to remove. For recent stains, an alkaline degreaser applied with a brush is usually sufficient. For old stains, treatment with specific products or even mechanical polishing may be necessary.

Prevention also helps: some communities install oil drip trays in parking bays or apply a sealant to the concrete floor to facilitate subsequent cleaning.

Regulations and obligations

The residents’ association is obliged to maintain common areas, including the garage, in adequate conditions of health and safety. Furthermore, garages above a certain size must comply with fire protection regulations, which includes keeping evacuation routes clean and clear.

Non-compliance can result in municipal fines and, in the event of an accident, civil liability for the community.

Advantages of outsourcing garage cleaning

Cleaning a communal garage requires equipment that most communities do not have: sweepers, industrial scrubbers and pressure washers. Hiring a professional company ensures the right equipment and products are used, that timelines are met, and that there is a responsible party to contact if any issues arise.

Additionally, regular professional cleaning extends the lifespan of the floor, improves ventilation by reducing airborne dust, and prevents damp and bad odour problems.
