Acid degreaser formulation



December 7, 2011

Sir,
what should be the actual percentage of acid content and actual percentage of solvents in acidic degreaser preparation used for cleaning mild steel?

Hi, Ashok. You probably already know this, but since this is a public forum and we don't want to mislead readers who come upon the thread --

The overwhelming majority of aqueous cleaners/degreasers are strongly alkaline rather than acid. There are a number of reasons for this, including the saponifying strength of strong alkalis. Solvent cleaners like trichlorethylene and perchlorethylene are not, to my knowledge, either acidic or alkaline.

There are hundreds of different formulations for cleaners/degreasers for mild steel depending on the type of soil, the operating temperature, whether they will be electrified for electrocleaning, how we wish to separate the oil and grease, etc. Again, you may know this, but for the benefit of readers, users of cleaners do not in general formulate their own, but they work with a process supplier to pick the most effective of the available preformulated cleaners/degreasers.

There are many such suppliers in Mumbai. Good luck.
