How to: Rust Removal Guide by Metal Type

1. Stainless Steel

Qualities

• Highly resistant to rust due to chromium content
• Forms a protective oxide layer
• Still can develop surface rust or staining if neglected or exposed to salt/water

How to Clean Rust

Gentle method (recommended first):

1. Mix baking soda with water into a paste
2. Apply to rust spots
3. Scrub lightly with a soft cloth or non-abrasive sponge
4. Rinse and dry thoroughly

For tougher rust:

• Use white vinegar:
• Soak a cloth and lay it over the rust for 15–30 minutes
• Wipe clean and rinse

Avoid:

• Steel wool or harsh abrasives (can damage the protective layer)

2. Aluminium

Qualities

• Lightweight and corrosion-resistant
• Does not rust (no iron), but oxidizes into a dull grey/white layer
• Soft and easily scratched

 How to Clean Oxidation

1. Mix equal parts white vinegar and water
2. Apply with a cloth or sponge
3. Gently rub the surface
4. Rinse and dry

Alternative:

• Lemon juice + salt for mild abrasion

Avoid:

• Strong alkaline cleaners (like bleach)
• Abrasive pads (they scratch easily)

3. Brass

Qualities

• Alloy of copper and zinc
• Develops tarnish (darkening), not rust
• Can be polished to a bright gold-like finish

How to Clean Tarnish

Natural method:

1. Mix lemon juice with baking soda into a paste
2. Rub gently onto brass
3. Let sit for a few minutes
4. Rinse and buff dry

Alternative:

• Vinegar + salt solution

Check first:

• If it’s lacquered brass, cleaning may damage the coating—test a small area

4. Copper

Qualities

• Excellent conductor of heat and electricity
• Develops patina (green/blue layer) over time
• Patina can be desirable or unwanted depending on use

How to Clean Tarnish/Patina

For bright finish:

1. Sprinkle salt over the surface
2. Rub with half a lemon
3. Rinse and dry

For heavier buildup:

• Use vinegar + salt solution
• Let sit briefly, then rinse thoroughly

Important:

• Always dry immediately to prevent new oxidation

General Tips (All Metals)

• Dry thoroughly after cleaning → moisture causes corrosion
• Test a small area first → especially for older or coated items
• Use soft tools → microfiber cloths, non-abrasive sponges
• Apply protective coatings (optional):
• Light oil (for tools)
• Wax or polish (for decorative items)
