CLEANING SOLUTIONS CONTAINING CITRIC ACID AND USES THEREOF |
摘要 |
An aqueous ammoniated citric acid cleaning solution effectively cleans metal parts at room temperature. The solution is prepared by diluting a concentrated aqueous citric acid solution containing between 1-10 % ammoniation, the concentrated solution being prepared in a special way. Dilution of this specially prepared concentrated solution provides a working solution which is much more effective in cleaning metal parts than conventionally prepared citric acid solutions which require hot temperature applications to work effectively.
