Fettüberzüge

Fettüberzüge, German for "fat coatings" or "grease coverings," refers to the accumulation of fatty or greasy substances on surfaces. This phenomenon can occur in various contexts, from industrial machinery to household kitchens. In industrial settings, fettüberzüge can result from lubricants, hydraulic fluids, or residues from manufacturing processes. Their presence can indicate leaks, wear and tear, or insufficient maintenance. On machinery, these coatings can attract dust and debris, potentially leading to reduced efficiency, increased friction, and premature component failure. Regular cleaning and inspection are crucial to manage fettüberzüge in industrial environments.

In domestic environments, fettüberzüge are commonly found in kitchens, particularly on stovetops, backsplashes, and exhaust hoods. These are formed by airborne grease particles from cooking, which settle and adhere to surfaces over time. This greasy film can be difficult to remove if left unattended and can become a breeding ground for bacteria. Effective cleaning often involves specialized degreasers and consistent wiping down of kitchen surfaces after cooking. Beyond kitchens, fettüberzüge can also appear on clothing or fabrics, often due to contact with oily foods or industrial lubricants. The removal of such stains depends on the type of grease and the fabric material, often requiring pre-treatment with stain removers before washing. The term generally denotes an undesirable build-up of fatty materials that requires attention for reasons of hygiene, performance, or aesthetics.
