How To Clean Cat Pee From Mattress In 10 Simple And Easy Steps

As a cat owner, the odds are high that you will come face to face with an unpleasant wet spot on your mattress at some point. Cleaning cat pee from a mattress may sound daunting, but with these ten easy steps, you can conquer the task swiftly and efficiently.

Step 1: Strip the Bed and Wash All Bedding in a Strong Detergent

Once you’ve detected that your cat has used your mattress as their makeshift litter box, it’s critical to immediately remove all bedding. This includes items such as covers, sheets, pillowcases, blankets, and anything else that may be affected.

You should then proceed to wash these items separately using a strong detergent. As stated by the American Cleaning Institute, an ideal choice of detergent is one that specifically specifies ‘pet odor eliminating’ properties on its label ACI’s Guide to Fabric Care Symbols.

Investing in such specialized detergents is important because typical household detergents might not be effective enough in completely eradicating cat urine smell from materials.

Make sure to set your washing machine to the hottest setting compatible with your particular bedding.

According to National Library of Medicine research on “Best Practices for Laundry Hygiene, warm water (between 104-140°F) is recommended coupled with either liquid chlorine bleach or color-safe bleach for colored items when dealing with organic spills like urine.

Step 2: Blot the Affected Area of the Mattress with Paper Towels or an Absorbent Cloth

Quick action is key. As soon as you notice your cat’s unfortunate deed, reach for some paper towels or an absorbent cloth. Use these to blot – not rub – the stained area. The goal here is to soak up as much of the offending liquid as possible from your mattress.

Push down onto the wet spot with enough pressure to absorb the moisture but not so hard that you push the urine further into your mattress.

Why blot instead of rub? Rubbing can cause the stain to spread and also pushes it deeper into mattress fibres, making it a lot harder to remove completely.

Dr. Michael Berry, Ph.D., who served as an expert witness for the Environmental Protection Agency, wrote in his book ‘Protecting the Built Environment‘ about cleaning tasks and systems. He emphasized that understanding basic cleaning fundamentals when dealing with stains like cat urine – such as blotting rather than rubbing – could significantly increase efficiency while reducing any lasting damage; sounds simple yet effective.

As per my experiments during previous cleanups, I’ve found that absorbent cloth is generally more effective than paper towels because it holds more liquid and is less likely to tear under pressure.

Such immediate actions might seem bare-basic but are critical initial steps towards ensuring long-term freshness and cleanliness of your mattress.

Step 3: Apply Pet Urine Enzyme Cleaner Liberally

Apply Pet Urine Enzyme Cleaner Liberally

Using a pet urine enzyme cleaner on the affected part of the mattress is essential in tackling this mess. This type of cleaner breaks down the proteins in cat pee, thus neutralizing the unpleasant odor.

Make sure you use a generous amount and follow the instructions on the product label for best results. A study by Sima Nandi and Suvendra K Ray suggests that biochemical cleansers like these successfully break down organic matter’s amino acids, reducing odorous compounds.

You should also try to ensure that this cleaner reaches as deeply into your mattress as did your cat’s urine. Simply pour it onto the affected surface area of your mattress and make certain that it seeps into the inner layers where lingering smells could be hiding.

Step 4: Let it soak for approximately 15-30 minutes

After blotting up as much pee as you can, it’s time to utilize a pet urine enzyme cleaner — a special cleaning substance designed to tackle pet-related messes. This solution contains specific enzymes that break down the proteins found in cat pee, effectively eliminating stubborn stains and odours.

You’ll need to apply the enzyme cleaner liberally on the affected area of your mattress. The product should then be left to soak into the mattress for between 15-30 minutes. However, it’s always important to read the instructions on your specific product; different cleaners may require varied soaking times.

Step 5: Blot up Remaining Moisture using Clean and Dry Towels

After working the pet urine enzyme cleaner into the mattress, it’s wise to allow the product to do its job for several minutes. However, don’t leave it soaking wet. Your next task is to remove as much of this liquid as possible.

Start by taking clean, dry towels and firmly press them into your mattress. You’re trying to lift as much moisture out of the fabric as you can. Be patient with this step; blotting requires a bit of elbow grease.

Switch to fresh towels when your current one gets too damp; reusing sodden towels will just return the moisture back onto the bed.

Avoid rubbing or scrubbing motions here- these can potentially spread the urine further and even grind it more deeply into the mattress fibers.

Your aim in this step is to remove as much of that leftover moisture from step 3 & 4. A drier mattress means less chance for mold growth and reduced lingering odor later.

Step 6: Sprinkle Baking Soda to Absorb Moisture and Neutralize Odors

After soaking the mattress with a pet urine enzyme cleaner and blotting it to remove as much uric acid as possible, the next line of defense is baking soda. Known for its moisture absorbing properties, baking soda effectively tackles lingering moisture in your mattress.

Be generous with your sprinkling; don’t hold back. Cover the entire affected area with enough baking soda, ensuring that it gets into the fabric. This allows the baking soda’s properties to break through any resistant odor particles still present.

Additionally, it’s vital to ensure that nothing disturbs this process for optimal results, which means keeping pets or children away from the area.

Baking soda isn’t just absorbing those unpleasant cat urine odors but also neutralizing them. Its natural deodorizing properties work by balancing pH levels in affected areas, thus eliminating strong and offensive smells.

Step 7: Leaving Baking Soda On The Mattress Overnight

Baking soda is such an amazing and versatile product. It has properties that not only help in absorbing moisture but also in neutralizing the odors that cat urine leaves behind.

To use it effectively, generously sprinkle the baking soda all over the area where your cat peed. Don’t be stingy with it – the more you cover, the better.

Once you’ve covered every inch of that spot, grab a good book or push play on your latest Netflix series because now you have to sit back and let it work its magic overnight.

When I say overnight, I mean a good 8-10 hours minimum. This gives baking soda enough time to absorb any remaining dampness and eradicate those nasty lingering smells.

Also, consider reading more about household cleaning tips from trusted sources like NSF. You’ll find various ideas for cleaning tasks using vinegar which can help if any tough stains remain once you’ve cleaned up after your cat’s mess.

Step 8: Vacuum Up All Baking Soda Residue From Your Bed The Next Day

When morning arrives, it’s time to get your mattress fully cleaned up.

Your main tool at this point is your trusty vacuum cleaner. To robustly absorb cat pee, we’ve left the baking soda on your mattress overnight. By morning, it will have worked its magic – creating a crust of sorts that has absorbed both moisture and odor.

Before you start vacuuming, ensure your machine has a clean bag or canister to avoid contaminating the process with existing debris.

Use the upholstery attachment if your vacuum has one; this facilitates effective sucking up of all baking soda residues without causing any damage to your mattress’s fabric.

Go over the entire surface of your bed with slow, even movements, ensuring that you don’t miss any spots where baking soda could be lingering.

This step might seem tedious but remember: the goal here is a fresh and clean mattress! Taking your time to thoroughly clean every area ensures no residue remains, which could discolor or damage your bed later on.

Step 9. Spot clean any remaining visible stains with vinegar diluted in water

If after all the previous steps you’re still facing stubborn stains, there’s a natural solution waiting in your pantry: vinegar. Vinegar is lauded for its ability to cut through various types of stains and eliminate odors.

Start by mixing equal parts white vinegar and water in a spray bottle. Apply this solution right onto the stain, then blot up the liquid with a clean cloth or paper towel. Repeat as necessary until you notice the stain disappearing.

Using vinegar not only helps in eliminating stains, but it also disinfects your mattress and neutralizes any lingering smell from cat urine. Outer appearances aside, this step ensures that we aren’t just disguising stains but are truly cleansing our mattresses.

Remember not to soak the mattress with this solution – a light spray is more than sufficient. Any excessive dampness can lead to other issues like mildew growth on your mattress, which is probably worse than any stain left by cat pee.

Whatever remains from step 8 should be resolved by vinegar – it’s that potent and effective given its acidic nature which combats alkaline urine stains quite well.

Step 10: Airing out Your Mattress

Allowing your mattress to have a solid period of airing out is the final step in ensuring that all remnants of pet urine are completely eradicated. It’s preferable to let your mattress sit uncovered for at least 24 hours. If possible, position the mattress under a ceiling fan or even outdoors in an area of direct sunlight – both have a rapid drying effect.

How does this work? The process of aeration eliminates any remaining moisture from the urine and the various cleaning products that you have used. This is essential because any left-over dampness can make your mattress prone to mildew and mold, which will result in another set of issues altogether.

While you may be tempted to rush this step, keep in mind that thorough drying is crucial. Hastily replacing bed linens might trap moisture, defeating all the hard work you’ve put into cleaning your mattress thus far.

In case you live in an apartment or it’s not possible to expose it to sunlight, consider using a blow dryer set at its coolest, pointing it towards the affected area as an alternate way to help speed up the drying process.
