Just gather a few key supplies and roll up those sleeves – it’s time to declaw that cat pee!

Supplies Needed: Your Cat Pee Cleaning Kit

To effectively remove cat urine from a mattress, having the right supplies is key. Here are the essentials you’ll need:

  • Baking soda – This pantry staple is a natural odor absorber. It will help soak up any lingering urine smells.
  • White vinegar – The acetic acid in vinegar helps neutralize odors and lift stains. Avoid colored vinegar.
  • Hydrogen peroxide – Its disinfecting properties will help sanitize the soiled areas.
  • Dish soap – A small amount of mild detergent like Dawn will help lift stains.
  • Enzyme-based pet stain cleaner – This breaks down the urine proteins that create odors. Look for one formulated for cat urine.
  • Spray bottle – For applying your cleaning solution to the affected mattress areas.
  • Clean cloths – For blotting up the cleaning solution and drying the mattress. White rags or paper towels work well.
  • Fans or dehumidifier – To help accelerate drying time after cleaning.

The next step is mixing up your cleaning solution using these ingredients. With the right concoction, you’ll be well on your way to sweet smelling sheets again!

Mixing the Cleaning Solution: Your Stain-Fighting Potion

Now that you’ve gathered your cat pee busting supplies, it’s time to mix up a cleaning solution that will break down stains and neutralize odors.

Here’s a simple yet powerful formula to use:

  • 1 part hydrogen peroxide
  • 1 part white vinegar
  • 1 teaspoon of dish soap
  • 1 teaspoon of enzyme cleaner
  • Warm water


  1. Add the ingredients to a spray bottle and fill the remainder with warm water.
  2. Shake vigorously to fully mix and dissolve the enzyme cleaner.
  3. Before spraying over the entire stained area, first test on a small, inconspicuous spot and let sit for 5 minutes. Check for any discoloration of the fabric.
  4. If no discoloring occurs, liberally spray over the affected area, saturating the stain. Some immediate bubbling may occur – that’s the hydrogen peroxide doing its work!

This solution contains the key ingredients needed to break down the compounds in cat urine that cause lingering odors and set stains. The dish soap helps lift organic stains while the enzyme cleaner targets the source of the smell. Once sprayed on, next comes gently blotting and drying. Let’s move on to tackling those pesky stains!

Applying the Solution: Blot, Don’t Scrub

You have your supplies gathered and cleaning solution mixed – now it’s time to put them to work erasing that cat pee stain!

Follow these steps for applying the cleaning solution:

  • Liberally spray the solution over the stained area, completely saturating it. Focus on the edges and underside of the mattress as cat urine can spread.
  • Allow the solution to sit for 5-10 minutes. This gives the enzymes and peroxide time to work their magic.
  • Gently blot the area with a clean white cloth or paper towels. Apply pressure to lift the stain, but don’t vigorously scrub.
  • Flip the cloth frequently to avoid spreading the stain. Use a patting motion to lift urine from the padding.
  • Continue blotting until the area is dry and no more urine is lifting onto the cloth.
  • Allow the mattress to fully air dry before using again. Place fans nearby to speed up drying.

Caution: Don’t leave your mattress saturated for too long. Prolonged moisture can lead to mold growth. Work in sections if needed.Be patient during this process.

It may take several rounds of spraying and blotting to fully lift out the stain and odor.

Drying the Mattress: Let it Air Out

Once you’ve tackled the stain and odor with your cleaning solution, the next important step is properly drying the mattress. This helps prevent mold or mildew growth.

Here are some tips for completely drying out your mattress after cleaning:

  • Allow 24-48 hours of drying time. This gives moisture from the cleaning process time to fully evaporate.
  • Place fans nearby to improve air circulation. Point them directly at the cleaned area.
  • Open windows if weather permits to allow fresh air flow.
  • Use a dehumidifier to actively draw out moisture from the mattress padding.
  • Flip and rotate the mattress occasionally to expose all sides to air.
  • Lay absorbent towels or cloths between the mattress and box spring to wick away moisture. Replace them often.
  • Don’t make the bed or replace sheets until fully dry.
  • Check for hidden damp spots by pressing your hand over the surface before reusing.

Take drying slow. Rushing the process can lock in moisture and odors.

Once completely dry, your mattress will be fresh, clean, and ready for a good night’s sleep!

Deodorizing: Sprinkle on the Baking Soda

Even once the stain is removed, you’ll want to take extra steps to fully neutralize any lingering cat urine odors. Baking soda is your secret weapon for mattress deodorizing.

Here is an easy process to banish remaining odors:

  • Liberally sprinkle baking soda over the affected area of the mattress. Really coat the surface.
  • Using your hands, gently rub the baking soda into the mattress fibers and padding.
  • Allow the baking soda to sit for minimum 1 hour, or ideally overnight.
  • Vacuum up the baking soda using the hose attachment. This will remove both the powder and absorbed odors.
  • Repeat as needed until cat urine smell has disappeared.

The baking soda will continue soaking up odors and should leave your mattress fresh and clean smelling. Its abrasive texture also helps lift odors from deep in the padding. Just take care not to rub too vigorously.

With stains removed and odors neutralized, your mattress will once again be a dreamy, cat pee-free oasis.

But let’s look at how to keep it that way!

Preventing Future Accidents: Stop it at the Source

Proper litter box training

  • Show your cat where the litter box is located and gently place them in it after meals or naps.
  • Use a litter attractant like catnip to entice them to use it.
  • Make sure the box is in a spot that’s easily accessible but offers privacy.

Clean the litter frequently

  • Scoop waste out daily and do a full change every 1-2 weeks.
  • Use unscented clumping litter and remove solids before ammonia odor builds up.

Add more litter boxes

  • Have one box per cat, plus an extra. This prevents territorial issues.
  • Place boxes in multiple areas your cat frequents.

Use litter attractants

  • Try commercial attractants or natural options like baking soda.
  • Avoid harsh chemical cleaners that may repel your cat.

With a little patience and these tips, you can redirect those bathroom urges away from your bed. A few key lifestyle changes will help prevent mattress cleaning from becoming a regular chore.

FAQ: Your Most Common Cat Pee Questions Answered

Cleaning cat urine stains can seem daunting, but it doesn’t have to be! Here are answers to some frequently asked questions:

Why is bleach ineffective for cat urine stains?

Bleach only removes the surface stain, not the urine salts deep in the padding. It can also set the stain by reacting with urine particles. An enzyme cleaner is more effective.

Is white vinegar safe for memory foam mattresses?

Yes, the small amount of vinegar used for cleaning is safe for memory foam. It dries quickly and won’t harm the materials.

What about dried or old urine stains?

Use an enzyme cleaner formulated for pet stains and allow more time for the enzymes to break down the urine crystals. Heat helps – try a steam cleaner.

Can I use a steam cleaner on a mattress?

Yes, use the attachments to focus steam on the affected area. Be sure to extract any moisture so it doesn’t sink deeper.

Any tips for preventing stains in the first place?

Use a waterproof mattress protector. They shield the inner mattress from accidents. Just take care to fully dry the surface before remaking the bed.
