What is the Difference Between Rust Converter and Rust Remover?

🆚 Go to Comparative Table 🆚

The main difference between a rust converter and a rust remover lies in their chemical reactions and practical applications. Here are the key differences:

Rust Converter:

  • Chemically reacts with rust, changing it into a different, inert compound still on the object.
  • Leaves a hardy coating of ferric phosphate.
  • Best used for corrosion control and protecting car bodies and fences.
  • Penetrates rust 7 to 10 times deeper.
  • Application is a simple and quick procedure.
  • Designed to bond to rust, so it won't work on non-rusty surfaces or mixed rusty and non-rusty areas.

Rust Remover:

  • Reacts with the rust to convert it into other compounds, which then separate from the object.
  • Strips the metal of rust, leaving a bare, metal surface.
  • Requires further processing, such as priming and painting, after rust removal.
  • Chemically reacts with the rust to strip any metal bare, ready for painting.
  • Separates the rust from the surface, providing a smoother surface for rust preventative paints and coatings.
  • Removal is a longer process that requires more time and effort compared to rust converter.

In summary, rust converters chemically change rust into an inert compound, while rust removers separate rust from the surface. Rust converters leave a protective coating, whereas rust removers require further processing after rust removal. The choice between the two depends on the specific application and desired outcome.

Comparative Table: Rust Converter vs Rust Remover

Here is a table comparing the differences between rust converters and rust removers:

Feature Rust Converter Rust Remover
Function Chemically converts rust to a non-tacky layer of ferric phosphate, providing protection for the treated surface Separates rust from the surface, leaving a bare, clean, and ready-to-paint surface
Application Easy to apply and allows you to apply additional barriers, such as paint and topcoats, on top Not as easy to apply as rust converters, requires more time and effort
Health and Safety Typically non-toxic and safer to use Can be toxic and require caution when handling due to the use of acidic ingredients, such as oxalic acid
Surface Preparation Leaves a stable and protective compound on the surface Requires further treatment, such as painting or other rust prevention methods, to protect the bare surface
Best Suited For Individuals looking for a simple, cost-effective, and safer solution for rust removal People who are willing to invest more time and effort into rust removal and are prepared for the chemicals involved

Both rust converters and rust removers effectively get rid of rust, but they work in different ways and have varying levels of difficulty and safety precautions. Rust converters are generally simpler, safer, and more cost-effective, making them a popular choice for many users. However, it's essential to consider your specific needs and preferences when choosing between the two options.
