ABSTRACT:
An organic acid anti-staining composition for glass sheets is disclosed herein whereby the corrosive effects of very low pH are eliminated by buffering the organic acid. The buffered organic acid has a less acidic pH, but is as effective as unbuffered organic acid in neutralizing alkali formed by sodium from the glass to prevent staining of the glass surface.
