The DOFF cleaning system is a highly effective method for cleaning sensitive surfaces, particularly those that require careful restoration, such as historic façades and older stonework. Unlike traditional jet washing, which uses high water pressure, DOFF operates at lower pressure and higher temperatures, reaching up to 150°C. This combination allows it to remove ingrained dirt, algae, and pollutants without causing damage to delicate materials like stone, brick, or timber.
One of the key benefits of the DOFF system is its environmentally responsible approach. By using less water and avoiding harsh chemicals, it reduces the environmental impact typically associated with cleaning. This makes it an ideal choice for buildings that are being preserved, as it helps maintain the integrity of historical or delicate surfaces.
The DOFF system is versatile and can be used in a variety of settings, from heritage sites to industrial applications. It is effective in removing dirt from brick and stone surfaces and is particularly useful for graffiti removal. The system also eliminates biological growth such as moss, algae, and fungi, which can degrade façades over time. Additionally, it is used in industrial environments to remove stubborn contaminants like grease and oil.
Working with a DOFF-approved contractor ensures that the cleaning process is carried out by trained professionals who use the latest technology. These contractors provide tailored solutions based on the specific needs of each building, helping to preserve both its appearance and structural integrity.
