About Rouging Solutions

What does Rouging Solutions do?

Rouging Solutions inspects, monitors, and maintains the stainless steel equipment in regulated plants, and keeps it compliant with global standards. We do that through eight services: inspection, frequency-based monitoring, cleaning, derouging, passivation, mechanical polishing, descaling, and electropolishing. Every job comes with the relevant documents, so your surfaces and your paperwork both hold up when an auditor asks. We use citric acid based methods that are safe for workers and the environment, and we serve plants across India.

The Full Loop

Inspect, monitor, maintain, comply

Most plants call us when they can already see a problem. The work is bigger than that, and it runs in four parts.

1

Inspect

We find out what condition your surfaces are actually in, using imported, fully calibrated instruments rather than a visual guess.

2

Monitor

We come back on an agreed frequency, so you catch the next problem while it is still small and cheap.

3

Maintain

We clean, derouge, descale, polish, and passivate, so the surface goes back to a known standard and stays there.

4

Comply

We hand over the records. Global compliance is not just doing the work, it is being able to show what was done, when, by what method, and to what result.

That is the full loop, and the last part is the one most suppliers leave out.

Plain Explainer

What is rouging?

Rouging is a reddish or dark stain that forms on stainless steel over time. It looks like rust and can flake into your product, which is a serious problem in pharma and food plants. There are three types: Class I is reddish iron oxide, Class II is a gray-blue iron-chromium oxide, and Class III comes from pitting. We find the type, remove it, and passivate the surface so it stays clean for longer.

Our Services

Every one of these comes with the relevant documents for your compliance file.

Our difference

Why we use citric acid instead of nitric acid

Older passivation uses nitric acid, which is dangerous to handle, gives off toxic fumes, and is hard to dispose of safely. We use citric acid based CitriSurf products instead. It does the same job, is safe for your team, is kinder to the environment, and meets ASTM A-967 Practice A.

Traditional Passivation

Nitric Acid (Old Way)

✕ Dangerous to handle

✕ Gives off toxic fumes

✕ Hard and costly to dispose of

✕ Extra safety burden on your team
