Rouging Solutions cleans, passivates, and de-rouges stainless steel equipment for factories in regulated industries. Passivation rebuilds the thin protective layer on steel so it does not rust. Derouging removes rust-like stains, called rouge, from tanks, pipes, and reactors. We use citric acid based methods that are safe for workers and the environment, and we serve plants across India.
We clean, restore, and protect stainless steel equipment using safer citric acid based processes designed for regulated industries.
We clean the inside and outside of your equipment using a citric acid based process that is gentler than traditional cleaning chemicals.
We rebuild the protective layer on stainless steel using CitriSurf citric acid technology, so the surface resists rust and stays compliant.
We remove rouge stains from tanks, reactors, and pipes, then passivate so the stains do not come back quickly.
We check surface quality and test for problems before they cause a failure or an audit issue.
We smooth and finish surfaces so they are easier to keep clean and pass inspection.
We remove hard scale build-up from stainless steel equipment so it works and cleans properly.
We help equipment makers and pipe fabricators build passivation into their own production line.
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.

My company installed a stainless steel job and just 60 days later I was called to the site to review what was reported to be terrible rusting. Needless to say there were some unhappy people. We called Stellar Solutions and was provided with product recommendations. The ‘after’ pictures speak for themselves. I couldn’t possibly tell you how happy I’ve been since then using Stellar products. Impressive and long-lasting results over and over. Thanks!
That's great. A big thank you again for your 'Stellar' customer service and rapid response. I am very grateful.
I really appreciate your promptness. You have a customer for life on passivation chemicals.
OK - I’m impressed. I can honestly say that I’ve never dealt with a company before that gave such fast and helpful replies. You raised the bar for me... By a lot.
Thank you !! Great customer service!
Wow! You are like lightning speed! Amazing customer service! Thank you once again, you were a pleasure to talk to and extremely helpful.
Thank you we received the shipment today. Oh and thanks for the Outstanding customer service!!!!!!!
Wow, that was amazingly fast. Thank you so much! I really appreciate it…
Thank you! You guys are so efficient and fast!
I was not going to expect to much on your product, as in the past with other company's I was not very happy with the results. The 2310 did a great job and so did the 9310. We will use your products again on future jobs. Thank you.
I’m very happy the way the Citrisurf has reclaimed the effected lines - I do believe we got the correct solution for the job in the 8050. Thanks for your product – this is so much better than nitric acid!
We would have spent 10’s of thousands of dollars without Citrisurf to replace the lines, and quite possibly have the same result – as the purging of the Orbitally Welded lines was the main suspect to our problem. Orbital welds are not generally passivated in my experience, but Citrisurf makes it easy. Stellar Solutions saved our bacon that’s for sure! Thanks for a great product that’s easy to use.
I received your product the other day and I just wanted to let you know we think it is FANTASTIC!! We definitely will be ordering more in the future as needed. Thanks again!!
Wow! Your product is amazing. My hot tub looks better than the day it was installed. Thank you!

Yes. Our field teams travel to client facilities across India for on-site passivation, derouging, cleaning, and inspection work.
Citric acid passivation is safer for operators, easier on the environment, and still meets ASTM-oriented stainless steel surface treatment requirements when applied correctly.
