Bionil PF Pre-Cleaning
Weld and Surface Pre-Cleaning Liquid
Pre-cleaning liquid that removes fabrication contamination, oil, grease and light pitting from stainless steel and other non-ferrous metal surfaces.
NSF-Certified, VOC-Free Multi-Purpose Cleaner

NSF-Certified, VOC-Free Multi-Purpose Cleaner
Removes oil, grease, process soils, pigment and protein residues from all kinds of surfaces such as metal, wood, plastic, ceramic and marble. Used diluted at a ratio of 1:10 to 1:40 with water heated from room temperature up to 60-80°C. Heat shortens the cleaning time and makes it easier to remove deeply hardened soils. Since it holds NSF certification, it is safely used in the food industry. The surfactants it contains are biodegradable. It holds the ÖNORM B 5105 Waste Certificate. Harmless to the user and the environment. Foam-free and corrosion-protective. Safely used in place of many solvents such as gasoline, acetone and trichloroethylene. Applied manually or mechanically by wiping, spraying or immersion.

Yes, an industrial cleaner holding this triple certification at the same time is rarely found in the industry. NSF certifies food-contact compliance, VOC-free certifies that it contains no volatile organic compounds, and ÖNORM B 5105 certifies that it does not cause clogging in waste-water treatment systems. It provides a critical advantage for manufacturers exporting to the EU and US markets.
Bionil S is the safe alternative in all applications where gasoline, acetone or trichloroethylene are traditionally used, such as machine maintenance, engine washing, parts degreasing, workshop floor cleaning and food machinery servicing. Fire risk, health effects and waste problems are eliminated.
Foam disrupts cavitation in ultrasonic baths, pressure washing machines and pump-circulation systems, drains the pump and reduces system efficiency. With its foam-free formula, Bionil S circulates trouble-free inside industrial cleaning equipment.
On amphoteric metals such as aluminium and zinc coating, a higher dilution of 1:30-1:40 is recommended to protect the surface. Use neat or at strong concentrations such as 1:10 may cause dulling or staining on the surface.
