Frequently Asked Questions
What are pickling products used for?
Pickling products are used to remove surface imperfections from stainless steel and other metal alloys. This is done through a chemical reaction. The primary purpose of pickling is to remove impurities, scale, rust, and oxides from the surface of a metal. This helps to leave it clean and ready for further processing.
What are the types of pickling products?
The most common types of pickling products are pickling paste, pickling spray, and pickling bath solutions.
Pickling paste is a thick gel paste that can be applied directly to the metal surface. It’s ideal for minor imperfections on flat or curved surfaces. The paste uses chemicals like hydrochloric or nitric acid to dissolve the imperfections. You then neutralise and rinse the area.
For larger-scale pickling, pickling spray and pickling baths are ideal. Pickling sprays are convenient and easy to apply. Pickling baths submerge the entire metal part in a chemical bath. The bath removes imperfections and restores the surface to a uniform finish.
What are the benefits of using pickling products on metals?
The primary benefit of pickling products is that they help prevent rust and corrosion. This is done by removing oxidation and built-up contaminants from the surface of metals. Pickling pastes and sprays create a clean surface that is less prone to corrosion. This is especially useful for metals that will be welded, soldered or joined in any way.
How do I use pickling products properly and safely?
You should always follow the instructions provided on the safety data sheet or product labels. Make sure to use these products in a well-ventilated area and wear proper protective gear. After pickling, thoroughly rinse the metal with water to remove any remaining acid residue.
Also, ensure to never pour used pickling solutions down drains or dispose of them in general waste. Dispose of all used solutions, rinse water and waste as per the directions given and as required by local environmental regulations.
