Causes of Rust
Rust forms when iron or steel are exposed to oxygen and moisture over a period of time. The three key factors that contribute to rust formation are the presence of iron, oxygen, and moisture. Iron is the most common element found in rust as it readily oxidizes when these three elements combine on the metal surface. Some of the common causes of rust include:
- Exposure to Air and Water: Iron will start rusting when it comes into contact with moisture in the air or water. Areas exposed to weathering such as outdoor patio furniture are more susceptible to rust formation.
- Harsh Environmental Conditions: High humidity levels, coastal areas exposed to saltwater, and areas with heavy industrial pollution accelerate the rusting process.
- Damage to Protective Coatings: Nicks or scratches in paint, Rust Remover enamel or other protective coatings allow moisture and oxygen to reach the base metal and initiate rusting.
- Poor Drainage Areas: Places where water tends to pool like window sills, below gutters, or inside wheel wells are prime locations for rust to develop.
- Bacteria or Fungus Presence: Microscopic organisms that thrive in damp conditions can influence the corrosion of some metals.
Rust Removal Methods
Wire Brushing or Sanding
For light surface rust, using a wire brush or fine-grit sandpaper can easily remove loose flakes. This method works best on flat, accessible surfaces. It doesn't penetrate deep pitting but cleans up overall appearance.
Chemical Rust Removers
Commercial rust removal solutions contain chemicals that break down rust. Apply, let sit as directed, then scrub off residue. These work well but require safety gear and proper disposal. Citric or vinegar-based removers are gentle alternatives.
Electrolytic Rust Removal
This process uses an electrical current to dissolve rust molecules. A power source connects the object and anodes placed in a tank of electrolyte. It works on all metals and penetrates deep but requires equipment and expertise.
Soft Wire Wheel on a Drill
For intricate or hard to reach areas, a drill-mounted wheel with soft steel or nylon bristles can spin away rust quickly without damaging base metal. Go slow, apply light pressure to grind it off evenly.
Sandblasting
For large, heavily rusted surfaces, sand or media blasting gives professional results. Air or spray guns propel an abrasive to cut through extensive corrosion. It cleans thoroughly but is messy, expensive for homeowners.
Paint/Primer Protection
Once thorough cleaning reveals bare metal, applying a rust inhibiting paint or primer forms a barrier against future oxidization. Enamel, epoxy and zinc-rich formulas shield iron especially underneath.
Rust Proofing Car Parts
Undercarriage Kit
A complete rust protection package sprayed inside vehicle bodies, frames and undercarriages coats over 180 vulnerable areas. Products use waxes, oils or corrosion-inhibiting chemicals that penetrate cracks to seal against moisture for years. Installation requires car to be raised on a hoist.
Single Component Undercoating
For spot-treating rusted car sections like wheel wells, floors or door bottoms, a single component spray-on undercoating forms a flexible and long-lasting barriers. Application requires masking nearby areas before spraying a thickness of protective coating.
Cavity Wax or Aerosol
For small hard to reach crevices on car bodies, cavity waxes or aerosols are brush or sprayed in to fill seams and bolt holes. Tacky formulas adhere and shield against corrosion inducing elements better than regular lubricants like oils.
With so many rust removar methods available, choosing the right one depends on the severity of corrosion, material being treated, and one's skill level and budget. Light duty wire brushing or chemical treatments work for surface rust, while heavy duty abrasives, electrolysis or complete undercoating systems apply to extensive oxidation cases. Proper preparation, careful cleaning and using a rust preventative seal after gets long-lasting results. Regular maintenance also helps keep oxidization at bay longer. With the right approach, rusted metal can often be restored instead of replaced.
