1. By chemical content
| Type | Properties | Advantages | Disadvantages | Application Area |
|---|---|---|---|---|
| Acid-based rust removers (phosphoric, citric, nitric acid) | Dissolves rust on metal surfaces, removes oxide layer | Fast-acting, deep rust cleaning | May have corrosive effect on metal, requires protective measures | Steel and iron surfaces |
| Alkali-based rust removers | Contains hydroxide, dissolves and washes away rust and dirt | Safer, non-corrosive to metal | Slower action | Light rust, surface cleaning |
| Solvent-based rust removers | Cleans surface rust along with oil and dirt | Versatile, can be used with oil | Insufficient for deep rust | Industrial machinery, engine parts |
| Electrochemical rust removers (rust removal baths) | Dissolves rust with electrical and chemical action | Suitable for delicate parts, controlled | High cost, special equipment | Delicate metal parts, automotive, electronics |
2. By physical form
- Liquid/solution: Easy to apply, used by spraying or dipping
- Gel/creamy form: Does not drip on vertical or horizontal surfaces, long-lasting effect
- Spray: Quick application and access to hard-to-reach spots
3. Selection criteria
- Metal type and surface sensitivity
- Rust density and depth
- Working environment (enclosed, open, humid)
- Need for surface protection after cleaning
- Occupational safety and environmental compatibility
