Use SciFinder, Scopus, Web of knowledge or other databases. Or simply Google!

Thanks a lot for your valuable suggestion Sir, but unfortunately we don't have the facilities of SciFinder and Scopus. And I did google as well, but I couldn't get anything regarding it.

Thats why I posted over here expecting something like Journals/Reviews/Chapters, etc from Experts like you.

Thank you.

Cheers...

Sulphamic acid is sold in the US as retail household "Coffee Cleaner" for plastic containers and glass carafs. I currently don't have a brand name in mind.  It is diluted with water (distilled is best) from a pint size bottle

say 250 ml

Perhaps, the manufacturer has a technical service person or department with many real world suggestion as to what it "removes"
