STAVICHEM PICKLING GEL
Pickling gel, also called stainless pickling paste, is a specialised chemical for cleaning and restoring stainless steel surfaces, particularly after welding pickling operations and fabrication. High temperatures during welding leave stainless steel with heat tint, oxide layers and other surface discolourations, which can affect both its appearance and its corrosion resistance. STAVICHEM PICKLING GEL removes these impurities effectively, leaving the stainless steel clean, uniform and corrosion-resistant. It is widely used in fabrication workshops, manufacturing plants and maintenance operations to preserve the durability and performance of stainless steel components.
Product details
Key Features and Benefits
STAVICHEM PICKLING GEL is a dependable stainless steel weld cleaning gel for anyone who works with stainless steel. Its distinctive formulation brings several advantages:
Takes Off Heat Tint and Oxide Scales
The gel dissolves weld oxides, heat tint and other discolorations on the surface that can undermine corrosion resistance, so the stainless steel keeps its protective properties.
Gel Consistency Makes Application Easy
Unlike liquid cleaners, the gel clings to vertical or uneven surfaces. That makes it ideal for welded joints, pipes, tanks and complex structures, giving thorough cleaning with no dripping.
Better Surface Appearance
The gel clears weld marks, stains and surface contaminants and leaves a clean, smooth, uniform finish, which helps both appearance and readiness for inspection.
Brings Back Corrosion Resistance
By removing impurities and re-establishing the chromium oxide layer, the gel returns stainless steel to its natural resistance to corrosion.
Reliable and Safe
Made for industrial and fabrication settings, the gel gives consistent results and is easy to handle and apply.
Specifications
This stainless steel pickling gel, which works in the same way as a pickling paste for stainless steel, is formulated to clean, restore and protect stainless steel surfaces, and suits industrial and fabrication applications.

Properties
Pickling gel has a few key properties that make it effective for cleaning and restoring stainless steel surfaces:
Strong Chemical Action
The product can dissolve unwanted layers on the metal, such as rust, oxides or the discoloration that appears during welding, and it uncovers the clean, bright metal beneath.
Gel-Based Consistency
It is thick like a gel rather than runny like water, so it stays put on walls and angled surfaces without dripping and cleans evenly all over.
Controlled Reaction Speed
The chemistry is neither too quick nor too slow. You have time to spread it evenly, so the entire surface is cleaned properly without streaks or spots.
Restores Corrosion Resistance
Stainless steel resists rust thanks to a thin chromium layer. The product helps rebuild that protective layer after welding or cleaning, so the metal remains strong and rust-free.

Frequently Asked Questions
How does pickling gel differ from pickling paste?
The two terms are often used interchangeably. Both are thick, brush-on formulations for cleaning stainless steel welds. STAVICHEM PICKLING GEL has a gel consistency that clings to vertical and overhead surfaces without dripping, so it serves the same applications as a stainless pickling paste.
How do you use pickling gel after welding?
Welding pickling means applying the gel to the weld area once welding is done. Brush the gel over the heat-affected zone, leave it for the recommended dwell time so it dissolves oxides and heat tint, then rinse with water. This restores the chromium oxide layer and the corrosion resistance of the stainless steel.
Is pickling gel suitable as a stainless steel weld cleaning gel?
Yes. STAVICHEM PICKLING GEL is designed specifically as a stainless steel weld cleaning gel. It removes heat tint, oxide scale and weld discolouration from stainless steel surfaces, restoring appearance and corrosion resistance after welding or fabrication.
Which surfaces can pickling paste for stainless steel be used on?
Pickling paste for stainless steel works on all austenitic, ferritic and duplex stainless steel grades. It can be used on flat surfaces, pipes, tanks, structural joints and complex welded assemblies. Do not use it on carbon steel, galvanised surfaces or aluminium.
For how long should pickling gel stay on the surface?
Dwell time depends on how severe the weld discolouration is and on the ambient temperature. In general, 30 to 60 minutes is enough for standard heat tint removal. Heavier oxide scale may need a longer dwell time or a second application. Always rinse thoroughly with water once the reaction is complete.
