Why Stainless Steel Sinks Need Special Care
Stainless steel is strong — but it's not invincible. Over time, hard water, acidic food residues, and abrasive tools can cause dullness, spotting, and corrosion. Regular maintenance helps:
- 🧼 Prevent mineral buildup
- ✨ Maintain a mirror-like shine
- 🛡️ Preserve the protective layer on the metal surface
Daily Maintenance Tips
Keep your sink looking great day-to-day with these habits:
- 🚿 Rinse thoroughly after each use
- 🧽 Wipe dry with a microfiber cloth to prevent water spots
- 🥫 Avoid leaving cans, cast iron, or steel wool in the sink — they can cause rust

How to Deep Clean a Stainless Steel Sink
Follow this simple process for a weekly or monthly reset:
- Clear and rinse: Remove any dishes or debris and rinse the sink with warm water.
- Apply cleaner: Use a plant-based stainless steel cleaner like Therapy Clean. Spray generously across all surfaces.
- Scrub gently: Use a soft sponge or cloth, working in the direction of the grain to avoid scratches.
- Rinse & dry: Rinse thoroughly and dry with a microfiber cloth to prevent spots.
How to Remove Stains, Rust, and Hard Water Spots
Even with regular cleaning, buildup can occur. Here's how to treat it:
💧 Hard Water Spots
These are caused by mineral deposits. Use a small amount of diluted white vinegar to break them down, then wipe immediately. Do not let vinegar dwell on the surface—it’s an acid and may compromise the finish over time.
🧪 Rust or Orange Spots
Create a paste of baking soda and water. Apply to the area and gently scrub with a soft brush or sponge, following the grain. Rinse and dry thoroughly. For persistent spots, try a cleaner containing oxalic acid (but avoid abrasive powders).
🔥 Burn Marks or Discoloration
These are often from hot pans. Use a non-abrasive stainless-steel-safe cleaner and gently polish the surface. Avoid steel wool or bleach-based products.
How to Restore Shine and Prevent Future Build-up
Once clean, you can finish with a polish to protect and shine:
- Ensure the sink is dry — water will prevent polish from bonding properly.
- Apply polish: Use a stainless steel polish like Therapy Clean with a soft cloth.
- Buff in the direction of the grain until the shine returns.
Repeat every 2–4 weeks to keep your sink looking new and resist fingerprints and spots.
