Before You Start

Before cleaning, remove all bedding and bedding accessories. Place the mattress on a flat, dry surface or elevate it to access both sides. Avoid using hot water or heat sources on the mattress during cleaning, as heat can set stains and odors.

Time estimates vary by mattress size and drying conditions, but plan for at least 4–24 hours of drying time. If the urine is recent or there’s a strong odor, increase ventilation, use fans, and consider a second cleaning pass.

Step-By-Step: How To Clean A Bed Mattress That Was Pee On

  1. Blot the area with a clean microfiber cloth to absorb as much liquid as possible. Press firmly but do not scrub, which can push urine deeper into the fibers.
  2. Apply a neutralizing approach by splashing a small amount of cold water onto the stained area and blotting again. This step helps dilute the urine without introducing heat.
  3. Pre-treat with enzyme cleaner according to product instructions. Enzyme cleaners break down urine proteins, reducing odors and preventing staining. Allow the cleaner to sit for the recommended dwell time.
  4. Rinse lightly with a minimal amount of water or use a damp microfiber cloth to remove excess cleaner. Blot thoroughly to remove moisture.
  5. Use a steam cleaner for mattresses urine to apply controlled moisture and heat, following the device’s guidelines. The steam helps lift residues without oversaturating the mattress.
  6. Extract moisture with a portable carpet cleaner for urine mattress or a wet-dry vacuum. Suck up as much liquid as possible from the surface and inner fibers.
  7. Apply an odor eliminator spray for mattress urine in a light, even mist. Target both the top surface and the sides to address any hidden odors. Allow to air dry.
  8. Dry thoroughly with fans or a dehumidifier. If feasible, place the mattress in direct sunlight or a well-ventilated area to speed up drying. Flip and rotate the mattress to ensure even drying.
  9. Check for lingering smell or stain after initial drying. If odors persist, repeat enzyme treatment and odor control steps, ensuring complete drying between passes.
  10. Reassemble bedding once the mattress is completely dry. Consider a mattress protector to simplify future cleanups.
  11. Optional preventative step use a fabric-safe protective spray on the mattress surface after cleaning, if recommended by product labels.

Troubleshooting

Symptom Likely Cause Fix Prevention
Persistent urine odor after cleaning Insufficient drying or incomplete enzyme action Repeat enzyme treatment and extend drying time Use a mattress protector and clean promptly after incidents
Stains remain after cleaning Deep penetration into foam or padding Spot-clean with enzyme cleaner and consider professional upholstery cleaning if needed Address spills quickly to prevent setting
Moisture pooling inside mattress Over-wetting during cleaning Use a wet-dry vacuum to extract moisture and increase airflow Avoid saturating coatings with water
Moldy or musty smell after drying Inadequate ventilation Increase air exchange, use dehumidifier Keep room dry during drying

Common Mistakes

  • Using hot water or heat on the mattress, which can set stains and odors
  • Over-wetting the mattress, leading to extended drying times and possible mildew
  • Skipping enzyme cleaners or relying on deodorizers alone
  • Not pre-testing cleaners on a small hidden area for colorfastness

Tips For Best Results

  • Test any cleaner on a hidden area of the mattress first to ensure no color transfer
  • Work from the outside edge toward the center to prevent spreading the stain
  • Ventilate the room well and use fans to speed up drying
  • Consider a water-resistant mattress protector for future incidents
  • Keep a routine with enzyme cleaners for pet-related accidents to maintain freshness

Call A Professional

If the urine exposure was extensive, if the mattress has absorbed into deep padding, or if odors persist after a thorough cleaning, consider consulting a professional upholstery or mattress cleaning service. Seek help immediately if there are signs of mold, persistent dampness, or allergic reactions around the sleeping area.

Buying Guide

When choosing cleaning tools and products for urine on a mattress, consider several factors to ensure effective cleaning and odor control. Size and type of mattress affect cleaning approach, while equipment choices impact results and ease of use.

Size and type: A standard twin, full, queen, or king may require different quantities of cleaner and more thorough drying efforts. Foam mattresses may hold liquids differently than innerspring or hybrid models, so adjust cleanup steps accordingly.

Enzyme cleaner performance: Look for enzymes designed for urine on fabrics and upholstery. Choose products with clear dwell-time instructions and safety data for home use.

Odor control: Odor eliminator sprays can help, but combining enzyme cleaning with odor control yields best results. Use sprays sparingly and ensure proper drying to prevent masking odors.

Moisture management: A steam cleaner can assist with controlled moisture, while a portable carpet cleaner helps extract liquids. A wet-dry vacuum is another effective tool for removing residual moisture.

Materials compatibility: Verify that microfiber cloths and cleaning tools are safe for the mattress surface and avoid rough scrubbing that can damage fabrics.

Protection and prevention: After cleaning, invest in a high-quality mattress protector to simplify future cleanups and extend the mattress life.

Placement considerations: Clean in a well-ventilated area. If possible, arrange airflow to reach both sides of the mattress to speed up drying and reduce odor retention.
