All ProductsFeatured formulas and equipment
Ordered along the surface treatment protocol: from degreasing through passivation and protection. All documented, all available as samples.
PF
P1Bionil P1 Immersion
Immersion liquid that removes heavy oxidation, pitting, rust and weld stains from stainless steel and prepares the surface for passivation.
P2Bionil P2 Pickling Paste
Brush-applied pickling paste that removes weld discolouration, heat-treatment scale, corrosion and rust stains from stainless steel weld zones.
P3Bionil P3 Pickling Spray
Spray formula that removes weld discolouration and large-surface stains by spraying. The P3S variant is designed for 300-series duplex stainless steels.
PRBionil PR Passivation Solution
Passivation solution that re-forms the passive layer on stainless steel surfaces in a very short time (0.06-0.08 µm).
Omni
NSF-certified protective spray used for cleaning metal surfaces and protecting them against external influences.
Inox One
Aerosol spray used to clean and polish matte and polished stainless surfaces. Removes fingerprints and prevents them from re-forming.
WBBionil WB Anti-Spatter
Prevents flying spatter and molten slag from sticking to the metal surface and the torch during welding, plasma and laser cutting. No corrosion occurs. Contains no silicone.
S 100Bionil OW S 100
General-purpose degreasing in pressure, rotary-basket and ultrasonic washing machines.
KBionil K Limescale Remover
A phosphate-free, biodegradable chemical that removes limescale, newly formed light rust, oil and grease deposits from metal surfaces.
BCBionil BC Bacteriological Cleaning System
VOC-free, NSF-approved complete equipment that economically removes all types of workshop soiling, drilling and cutting oils, greases and protective oils through a biological process.

Process flow
Animation in the Clean Lab Hybrid direction explains the process decision instead of decorating it. Users quickly see which product comes into play at each step.
- 01
Degreasing
PF removes oil, fabrication dirt and process residues from the surface.
A preparation stage so the chemical reaction contacts the surface evenly.
- 02
Pickling
P1, P2 or P3 dissolves weld discoloration and the oxide layer.
Brush, spray or immersion is selected according to part geometry.
- 03
Pressure rinsing
Chemical residues are removed in a controlled way with 150-bar clean water.
Rinse quality directly affects subsequent passivation performance.
- 04
pH and iron test
Litmus and Ferronil checks verify the surface has reached a safe level.
Acts as the quality gate that drives decisions in the field.
- 05
Passivation
PR reinforces the passive layer and raises the protection level.
Spray or immersion application is planned according to part volume.
- 06
Final inspection
Surface, documentation and service conditions are finalized by the technical team.
Product, duration and concentration recommendations are revised if needed.
- 07
OMNI / INOX ONE Protection
After passivation, OMNI or INOX ONE is applied for fingerprint removal, atmospheric protection and a long-lasting hygienic finish.
NSF-certified protective spray as the final coat; pre-delivery fingerprint and matte/gloss surface preparation.
