Cleaning vs. Sanitizing: Why the Difference Matters

Keeping kittens healthy isn’t just about what products you use—it’s about using them in the correct order. Cleaning and sanitizing are not the same thing, and one does not work properly without the other.

Cleaning Comes First (Always)

Cleaning = removing visible debris

Cleaning physically removes:

• Dirt

• Food residue

• Litter dust

• Feces, urine, and other organic material

Examples of cleaning

• Sweeping or vacuuming

• Scrubbing bowls, litter boxes, and surfaces

• Washing bedding, towels, and blankets

• Using soap and water

If you can still see grease or grime, the surface is not clean.

Sanitizing (Disinfecting) Comes Second

Sanitizing = killing germs left behind after cleaning

Disinfectants are designed to kill:

• Bacteria

• Viruses

• Fungal spores

• Other illness-causing organisms

Important: Disinfectants do not work properly on dirty surfaces. Organic matter blocks them from doing their job.

Sanitizing only works after cleaning removes debris.

The Correct Order (Every Time)

1. Clean – remove all visible debris

2. Rinse – if using soap or detergent

3. Sanitize/Disinfect – apply approved disinfectant

4. Wait – allow proper contact time (per product instructions)

5. Dry – air dry or towel dry before kittens return

Skipping cleaning and going straight to sanitizing is ineffective.

Why This Matters for Kittens

Kittens have:

• Immature immune systems

• High exposure to shared spaces

• Greater risk of parasites and viruses

Illnesses like panleukopenia, coccidia, giardia, ringworm, and URI viruses can survive in the environment if surfaces aren’t cleaned and sanitized properly.

What Needs Both Cleaning and Sanitizing?

• Food and water bowls

• Litter boxes and scoops

• Kennels, crates, and playpens

• Hard floors and surfaces

• Carriers

• Foster room surfaces during transitions

What Usually Needs Cleaning Only?

• Daily sweeping or vacuuming

• Routine laundry (unless illness is present)

• Toys in active daily use (unless soiled)

The Kitten Alliance may advise additional sanitizing during illness or quarantine periods.

Common Mistakes to Avoid

• Spraying disinfectant on dirty surfaces

• Wiping off disinfectant too soon

• Using too much product (more is not better)

• Mixing cleaning chemicals

• Skipping hand washing between litters

The Bottom Line

• You must clean BEFORE you sanitize.

• Cleaning removes debris.

• Sanitizing kills what you can’t see—after debris is gone.

Both steps together are what keep kittens safe.
