| Advantage | Details |
|---|---|
| Dual Activity | The acid group removes rust and scale build-up while the alcohol group chelates to keep impurities dissolved or dispersed. |
| Relatively strong organic acid | 4% solution of Glycolic Acid in water is below 2.0 pH. |
| Low volatility | Little corrosive fumes evolve on heating; low acid yield loss is experienced, even when solutions are used, non-VOC due to low vapor pressure. |
| Very mild odor | It does not fume as some mineral acids do. |
| Provides good rinsing properties | Dissolves and cleans rust, oxides, carbonate scales, and most casein scales readily, resulting in water-soluble salts. |
| Supplied in complete solution | Easy to handle as a liquid; no "incomplete dissolving" problems; 70% concentrate can be quickly water diluted to any desired strength. |
| Relatively low corrosion | Low corrosivity on metals can be further reduced by the addition of a corrosion inhibitor. |
| Contains essentially no chlorides | Can be used for cleaning stainless steel without the possible chloride cracking or embrittlement often experienced in acid chloride systems. |
| Compatible with many cleaning ingredients | These can include surfactants, biocidal agents, corrosion inhibitors, scents, colors, other acids, and, of course, water. |
| Provides complexing properties | This characteristic may preclude the need to add a special chelating or complexing agent and enhance the rinsability of the cleaner. |
| Relatively safe to store and handle | Always be sure to follow the safety data sheet guidelines. |
| Readily biodegradable | Waste disposal is not a problem and it does not support the growth of bacteria. |
