E.P. Weldex

E.P. Weldex. Product for the electrolytic pickling of metal.

General description

E.P. Weldex has been developed to support the electrolytic pickling of welded joints. Due to its careful formulation, its acid character helps to activate the top layer of the metal and to remove discolouration.


  • A dull appearance gives an untended look
  • After welding stainless steel/ Inox, discolouration occurs that gives the material an untended look
  • Discolouration is often where corrosion or other damage starts
  • Pickling and passivating is often associated with aggressive or even poisonous chemicals.
  • Spilt pickling agent immediately causes spots on the rest of the material
  • Human and environmentally hazardous products are difficult to use and to dispose of

The solution

E.P. Weldex is the product to use with electrolytic equipment in order to rapidly perform high-quality cleaning of welded joints, without producing hazardous substances.

Special advantages

  • E.P. Weldex is easy to use: apply via the cleaning pad of the cleaning device and use a (low) current
  • E.P. Weldex gives welded joints an evenly coloured appearance
  • E.P. Weldex does not emit poisonous gases when used
  • E.P. Weldex is non-corrosive, therefore safe to use and does not cause new discolouration. Does not contain nitric acid or hydrofluoric acid
  • E.P. Weldex does not leave spots on stainless steel/ Inox surfaces
  • E.P. Weldex has been specially developed and tested to remove discolouration from the welded joint using an electrolytic process.
  • E.P. Weldex is economical to use

The application

  • On discolouration of welded joints in stainless steel/ Inox in the metal industry, construction, mechanical engineering plants and in the food and other sectors where a lot of metal is used.
  • To be used in combination with weld cleaning equipment of various brands and manufacturers.
  • For manual application, possibly supported by an abrasive action (abrasive cloth or scourer), here, of course, the electrolysis effect is lost.


Ensure that prior to the treatment the surface is clean and dry. Use sparingly.

Working method

Always follow the cleaning equipment instructions. Connect the earth electrode to the metal, immerse the 'cleaning pad' in the E.P. Weldex (to be used undiluted) and wipe it over the discolouration. If the result is not satisfactory, increase the current and/or repeat the action.
If you have any questions or are in doubt, please consult your product consultant.
