Lüster EcoFactory pickling agent: professional guide for stainless steel and welds
A practical guide to using the Lüster EcoFactory acidic pickling agent on stainless steel and welds, with dilution and contact-time guidance.
Why this pickling agent is used on stainless steel
The Lüster EcoFactory pickling agent is designed for the professional treatment of stainless steel and welds. It removes weld oxides, scale and oxidation, helping restore the metal’s passive layer after treatment.
It is intended for situations where standard cleaning is not enough and a targeted technical treatment is required on stainless steel surfaces. The gel version is especially useful on vertical areas and welds where a more fluid product would not stay in place as effectively.
Step-by-step application method
For correct use, the concentrate should be diluted according to the indicated table, taking local water hardness into account. The prepared solution is then applied to the surface with a cloth, sponge or professional tool, spreading it evenly over the area to be treated.
After application, the specified contact time of 10 to 30 minutes should be respected. At the end of the dwell time, residues should be removed with a clean cloth or rinsed away with water to complete the treatment.
Dilutions and working yield
For ordinary soiling, the recommended dilution is 200 ml per 1 litre, giving a final yield of 5 litres of solution. For more intensive work, the dilution is 330 ml per 1 litre, with a final yield of 3 litres of ready-to-use solution.
On welds, the product can also be used pure when direct action is needed on the treated point. The choice between ordinary, intense or pure use depends on the oxidation level, the presence of scale and the condition of the stainless steel surface.
Laboratory advice for professional use
In professional use, controlling dwell time is essential. Allowing the product to work for 10 to 30 minutes makes it possible to adapt the treatment to the actual level of oxidation without working by guesswork. Recommended frequency is monthly or according to soil load.
For vertical welds or difficult areas, the gel version offers a practical advantage because it adheres better to the surface. This helps keep the product exactly where it needs to work, even on non-horizontal surfaces.
FAQ
What residues is this pickling agent designed to remove?
It is intended to remove weld oxides, scale and oxidation from stainless steel while helping restore the metal’s passive layer.
How long should it remain on the surface?
The indicated contact time is 10 to 30 minutes. The exact dwell time should be chosen according to the level of oxidation or soiling.
When is the gel version the best option?
The gel version is especially suitable for vertical surfaces and vertical welds because it adheres better and stays on the application area more effectively.
