Typical Pickling Process

A typical stainless-steel surface-treatment sequence is:

Degreasing → Pickling Paste Application → Rinsing → Neutralization → Final Rinsing → Passivation

The neutralizer is applied only according to the product manufacturer's instructions. Concentration, contact time, and application method depend on the pickling product, stainless-steel grade, surface condition, and site requirements.

 

DIRECTIONS FOR USE

1) Neutralisation of retained acidic waste For every litre of spent pickling waste, add approximately 1.7 litres of Pickling Paste Neutralizer. The Pickling Paste Neutralizer on contact with the spent acid waste will go clear. Keep on adding Pickling Paste Neutraliser solution till a faint pink coloration exist.

If neutralisation has not occurred with the initial dosage, then add additional quantities of Pickling Paste  Neutraliser at 100ml per litre of waste until colour change is observed.

2) Diagnostic Use After washing the pickling gel away and while still wet, spray thePickling Paste Neutraliser solution directly onto the area where the pickling gel was applied, in particular in corners and crevices. If residual acid is present an effervescent reaction will occur. Flush with water thoroughly once the effervescence has stopped.

Avoid contact with skin or eyes.
