Cat pee smell can feel impossible to remove, especially from soft, cozy furniture like a Lovesac. The key is using the right method for your specific Lovesac piece and the right cleaner that truly breaks down urine, not just masks it. This guide explains exactly how to clean both Sacs and Sactionals, how to handle covers and inserts, what to do for old stains, and how to keep the smell from coming back.
Know Your Lovesac: Sac vs. Sactionals
What a Sac is made of
A Sac is the large, round, cloud-like chair. It has a removable outer cover and an inner liner filled with shredded foam. The outer cover usually zips off and is often machine-washable depending on the fabric. The inner liner holds the foam and is not designed to be machine washed. If urine reaches the foam, you must treat it with an enzymatic cleaner and allow very thorough drying.
What Sactionals are made of
Sactionals are modular couches made of seats, sides, covers, and cushions. Many Sactionals covers are removable and machine-washable, but some premium or specialty fabrics may be dry-clean only. Always read the care label inside the cover. If urine soaks into the cushion foam or seat insert, you will need to treat the insert with an enzyme cleaner or consider professional help. For severe contamination, replacement inserts may be the most reliable fix.
The Science of Cat Pee Smell
Why the smell sticks around
Cat urine contains uric acid crystals that bond to fibers and foam. Standard detergents and many deodorizers cannot break these crystals down. Heat can also set the smell. An enzymatic cleaner designed for pet urine is the most effective way to digest the compounds that cause the odor.
What actually works
Enzymatic urine cleaners are the top choice. White vinegar and baking soda can help, but they rarely remove all uric acid by themselves. You may use hydrogen peroxide on light, colorfast fabrics with caution, but always test first. Never use ammonia products because they smell similar to urine and can attract repeat marking.
Gather Your Supplies
Basic toolkit for fresh or light stains
Have clean white towels or microfiber cloths for blotting, an enzymatic pet urine cleaner, cool water in a spray bottle, and baking soda for deodorizing. If possible, a wet dry vacuum or small upholstery extractor helps remove rinse water and speeds drying.
Extra tools for tougher jobs
Use a UV blacklight to find hidden spots. Keep gentle laundry detergent for washable covers, a fan for airflow, and a tarp or plastic to protect clean areas while you work. Gloves are helpful, and test swabs or cotton pads let you check colorfastness during spot tests.
If the Accident Is Fresh: Quick Action Steps
Blot first, then treat
Step 1: Blot up as much urine as possible right away using clean, dry towels. Press firmly to draw liquid out, and replace towels as they become wet. Do not rub because rubbing pushes urine deeper into fibers and foam.
Step 2: Lightly mist the area with cool water, then blot again. This helps dilute surface residue without spreading it.
Step 3: Apply an enzymatic cleaner generously. Urine can travel sideways and downward, so extend your treatment area an inch or two beyond what you see. Follow the label dwell time closely. Most need 10 to 30 minutes to work, and some recommend keeping the spot damp for longer.
Step 4: Blot thoroughly after dwell time. If you have a wet dry vacuum or upholstery extractor, use it to pull out the liquid. Repeat enzyme application and extraction as needed until odor is reduced.
Step 5: Sprinkle baking soda over the area after most moisture is removed. Let it sit until dry, then vacuum. Baking soda helps pick up any remaining acidic odors.
Cleaning Removable Covers the Right Way
Check the care label and pre-treat
Always look for the fabric care tag inside the Lovesac cover. If it says machine-washable, zip the cover closed and turn it inside out. Pre-treat urine spots with an enzymatic cleaner and allow the recommended dwell time. For heavy odor, pre-soak the cover in cool water mixed with a dose of enzymatic cleaner before washing.
Wash with care
Use a cold, gentle cycle with mild detergent. Avoid bleach and fabric softeners. If your machine has an extra rinse option, use it to remove all residue. You may add a cup of white vinegar to the rinse to help with odor, but do not combine vinegar with oxygen-based additives or peroxide in the same wash.
Dry slowly without heat
Air dry the cover flat or hang it to dry with good airflow. Avoid the dryer because heat can set any remaining odor and may cause shrinking. If the fabric label says tumble dry low is safe, you can use low or no heat, but air drying is still safest. Ensure the cover is fully dry before putting it back on.
If Pee Reached the Foam or Sac Liner
Confirm and plan
If you smell urine after washing the cover, the insert likely has urine too. Carefully unzip the cover and sniff the inner liner or foam. Use a blacklight in a dark room to spot contamination. Plan to treat the liner and foam directly with enzyme cleaner and allow extended drying time.
Saturate with enzyme, then extract
Urine seeps deep, so enzyme must reach the same depth. Apply enough enzymatic cleaner to fully penetrate the affected area. Allow the recommended dwell time. Afterward, press with towels or use a wet dry vacuum to extract. Repeat a second time for serious odors.
Rinse lightly and dry thoroughly
Lightly mist cool water and extract again to remove leftover cleaner. Then allow slow, complete drying with abundant airflow. Set the insert upright so air can pass on all sides. Aim a fan at it, and if weather allows, dry in a shaded, breezy spot indoors near an open window. Avoid direct hot sun on dark fabrics to prevent fading and avoid any heat that can bake in odor. Drying can take 24 to 72 hours depending on thickness and humidity.
When to replace inserts
If odor persists after two or three full enzyme and extraction cycles, the foam may be saturated beyond easy salvage. Lovesac sells replacement inserts for many products, and replacement is often cheaper and faster than multiple professional treatments. Keep any new inserts protected with a waterproof barrier to prevent future issues.
Special Notes for Sacs
Outer cover vs. inner liner
Remove and wash the outer cover according to its care label. For the inner liner and foam fill, do not machine wash. Instead, unzip the liner carefully and spot-treat the area through the fabric using an enzymatic cleaner. Gently massage the cleaner into the fill area from the outside so it penetrates. Allow dwell time, then blot and air dry thoroughly. Rotate and fluff the foam while drying to release moisture and speed airflow.
Drying a large Sac
Sacs are dense and take time to dry. Place the Sac on a clean tarp or breathable platform. Use multiple fans aimed at different angles. Turn the Sac every few hours the first day to expose new surfaces. Do not re-cover until the liner feels completely dry and the smell is gone.
Old, Dried, or Strong Odors
Rehydrate and re-enzymize
Dried urine must be rehydrated so enzymes can digest it. First, lightly mist the area with cool water. Next, apply a generous amount of enzymatic cleaner and allow a long dwell period. For deep set stains, cover the damp area with plastic wrap for one to two hours to slow evaporation and keep enzymes active. Then remove the plastic, blot or extract, and let it dry. Repeat this process as needed over one to three days for stubborn smells.
Follow with baking soda and time
After the last enzyme treatment has dried, spread a thin layer of baking soda over the area, leave it overnight, and vacuum well the next day. This helps grab leftover acidity and neutral odor traces that linger after enzymatic work.
What Not to Do
Avoid heat and steam
Do not use hot water, a steam cleaner, or a hot dryer on urine spots. Heat sets odors by binding uric acid deeper into fibers and foam. Always stick to cool water and air drying.
Do not use ammonia-based products
Ammonia smells like urine to a cat. Using it can cause repeat marking in the same spot. Choose pet-safe enzymatic cleaners instead.
Be cautious with peroxide and oxygen boosters
Hydrogen peroxide can lighten and discolor fabrics, especially dark or delicate ones. If you try a 3 percent peroxide solution, always test in a hidden area and dab gently. Never mix peroxide with vinegar in the same container or use both at the same time on the surface.
Avoid heavy fragrances
Strong perfumes and air fresheners do not remove urine crystals. Cats often still smell the spot and may return. Focus on complete enzyme treatment and proper drying for lasting results.
Quick Deodorizing Between Deep Cleans
Baking soda refresh
For a quick refresh after a deep clean, lightly sprinkle baking soda on a dry cover, let it sit for one to two hours, then vacuum thoroughly. This will not replace enzyme cleaning, but it helps control mild residual odors.
Airflow and indirect sunlight
Good airflow shortens dry time and cuts odor. Place cushions or Sacs in a bright, airy room with indirect sunlight. A fan aimed across the surface, not directly blasting it, helps moisture evaporate evenly.
Odor absorbers nearby
Place bowls of baking soda, activated charcoal, or zeolite odor absorbers near the furniture while it dries. They capture ambient odors in the room so you are not fooled by background smells when checking your progress.
Protect Your Lovesac from Future Accidents
Waterproof barriers
Add a thin waterproof liner or protector between the insert and the outer cover where possible. Even a temporary barrier while retraining your cat can save the foam from soaking. Make sure the barrier is breathable to avoid trapping moisture.
Litter box basics
Keep litter boxes clean and easy to access. A common rule is one box per cat plus one extra. Scoop daily and fully change litter weekly. If your cat suddenly starts peeing on furniture, talk to your vet to rule out urinary issues, stress, or pain. Cats often mark when anxious or when the litter box feels unsafe or dirty.
Discourage re-marking
After cleaning, use an enzyme cleaner over a wider area to eliminate invisible borders of scent. Consider calming aids or pheromone diffusers in rooms your cat targets. Offer scratching posts, playtime, and safe resting spots to reduce stress triggers.
Troubleshooting: How to Tell if Urine Remains
Use a blacklight in a dark room
Urine often glows yellow-green under a UV blacklight. Sweep it slowly over the surface. Outline glowing spots with small bits of painter’s tape so you can treat them all. After cleaning, check again to confirm progress.
Smell returns on humid days
If odor comes back when humidity rises or when the piece warms up, urine is still present somewhere inside. Repeat enzyme treatments targeted to likely hotspots and ensure more drying time with stronger airflow.
When to call a pro
For large, deep saturation or delicate, dry-clean-only fabrics, professional upholstery cleaners with pet urine treatment can save time. Ask if they use enzymatic or oxidizing urine removal processes and if they can extract moisture thoroughly without over-wetting foam.
Fabric Care Notes and FAQs
Are all Lovesac covers machine-washable?
Many are, but not all. Always check the care tag. If it says dry clean only, do not machine wash. For washable covers, use cold water, gentle cycle, mild detergent, and air dry to be safe.
Can I use a carpet or upholstery extractor?
Yes, if used carefully. Apply enzymatic cleaner first and allow dwell time. Then rinse with cool water and extract with the machine. Avoid over-wetting. Multiple light passes are better than soaking the cushion.
How long should drying take?
Covers may dry in 6 to 24 hours depending on fabric and airflow. Foam inserts and Sacs can take 24 to 72 hours or longer. Do not reassemble or cover until pieces are fully dry and odor-free.
Is vinegar enough on its own?
Vinegar helps neutralize odors but does not break down uric acid crystals fully. Use it as a helper during laundry or rinsing, but rely on a true enzymatic cleaner for deep odor removal.
What about leather or faux leather covers?
Wipe immediately with a damp cloth, then use a leather-safe cleaner or a pet-safe enzymatic cleaner tested first in a hidden spot. Do not soak leather. After cleaning, apply a leather conditioner to keep the material supple. For faux leather, test first and avoid harsh solvents.
How do I handle dry-clean-only fabrics?
Blot fresh urine right away. Lightly apply enzymatic cleaner to a small test area. If color is stable, treat the stain sparingly and blot. Do not saturate. Then take the cover to a professional dry cleaner and inform them about the urine so they can use appropriate methods.
Step-by-Step Summary for Most Situations
Fast cleanup checklist
Blot urine immediately with towels. Mist cool water and blot again. Apply enzymatic cleaner liberally and let it dwell per the label. Blot or extract thoroughly. Air dry with a fan. Treat the cover and the insert if needed. Wash washable covers in cold water and air dry. Repeat enzyme treatment for lingering odor. Use baking soda after drying, then vacuum.
Conclusion
Fresh, clean, and odor-free is possible
Getting cat pee smell out of a Lovesac takes the right approach: strong blotting, enzyme treatments, careful rinsing and extraction, and patient drying. Treat both the cover and the insert if urine has penetrated. Avoid heat and ammonia, use a blacklight to find hidden spots, and repeat enzyme treatments for older stains. Protect inserts with a waterproof barrier and keep your cat’s litter and routine dialed in to prevent future accidents. With these steps, your Lovesac can be fresh, cozy, and truly odor-free again.
