F OXALIC ACID

"CLEAN UP" IRON OXIDE PROBLEMS • For industry's continuing fight against rust, Pfizer offers these proven products:

CITRIC ACID. An important chemical in many metal cleaning pastes and liquid formulations for both home and industrial use. Solutions of citric acid, partially neutralized with ammonia, are ex­cellent rust and scale removers. Their use results in the least possible loss of metal. Moreover, citric acid has an extremely low order of toxicity.

AMMONIUM CITRATE DIBASIC. A dry product fo r

rust and scale removal with the same character­istics as the citric acid solutions partially neu­tralized with ammonia. It is of particular interest to manufacturers who market packaged home cleaners.

OXALIC ACID. Because Pfizer oxalic acid solubil-izes iron oxide, it is the chief ingredient in radi­ator cleaning compounds. Combined with a wetting agent, oxalic acid solutions also find extensive use in washing railway caiv and locomotives.
