Cleaning vs. Sanitizing: What’s the Difference?

Let’s start with a quick distinction:

• Cleaning removes grease, dirt, and visible residue.
• Sanitizing or disinfecting kills germs and bacteria—but only if the product is EPA-registered.

In other words, cleaning prepares the surface; sanitizing ensures it’s truly hygienic.

What to Use to Sanitize Stainless Steel

If you need to sanitize your stainless steel appliances or surfaces, here are a few safe options:

✅ Hydrogen Peroxide (3%)

Hydrogen peroxide is safe on stainless steel and acts as a mild disinfectant. Use a spray bottle to apply it directly to the surface and let it sit for at least 1 minute before wiping clean with a microfiber cloth.

✅ Isopropyl Alcohol (70%)

Rubbing alcohol is another effective sanitizing agent. It evaporates quickly and doesn’t require rinsing. Spray and wipe with the grain using a soft cloth.

✅ EPA-Registered Disinfectants

When in doubt, check the label for EPA registration.  Find the full database here and just follow contact time instructions closely.

How to Safely Apply Sanitizers

1. Start by cleaning the surface using a stainless-safe cleaner like Therapy Clean to remove grime and residue.
   
   
2. Spray your sanitizing solution (hydrogen peroxide, alcohol, or EPA-approved disinfectant).
   
   
3. Allow to sit for the required contact time—usually 1 to 10 minutes.
   
   
4. Wipe clean with a microfiber cloth in the direction of the grain.
   
   
5. Re-apply a stainless steel cleaner and polish to provide surface protection.

Note: Avoid using bleach or ammonia-based products on stainless steel—they can corrode the surface over time.

Common Sanitizing Mistakes to Avoid

• ❌ Spraying sanitizer without cleaning first (dirt reduces effectiveness)
• ❌ Using abrasive pads or steel wool
• ❌ Not following EPA-approved contact time
• ❌ Using bleach on stainless steel

Frequently Asked Questions

Can I sanitize stainless steel with vinegar?

Vinegar is not a registered disinfectant. While it can remove hard water spots, it won’t sanitize surfaces effectively and may dull the finish over time.

Is hydrogen peroxide safe on stainless steel?

Yes, 3% hydrogen peroxide is non-corrosive and can be used to sanitize stainless surfaces. Just don’t let it dwell too long—always wipe dry after use.

Do I need to rinse after sanitizing?

Only if you're using a chemical disinfectant with a strong residue. Alcohol and peroxide typically don’t require rinsing—but always read your product label.

What’s the safest sanitizer for a stainless steel sink?

Hydrogen peroxide or alcohol are great choices. Avoid bleach or chlorine-based products, especially if your sink has a brushed finish.
