To prevent dirt and debris from accumulating on the sofa bed, it must be cleaned regularly. To clean your sofa bed, vacuum and deodorize it, then remove any stains. Use a household product mixture to remove stains. Cover the sofa with a special cover to keep it clean.
Steps
Method 1 of 3: Cleaning regularly

Step 1. Vacuum the sofa bed
The first step is to thoroughly vacuum the sofa bed to remove dirt, hair, and other debris. Remember to fold out the sofa first. Go over it with a vacuum cleaner. Use an upholstery brush to clean all crevices and crevices. Flip the sofa bed over and vacuum it too.

Step 2. Deodorize the sofa bed
Over time, pull-out sofas start to smell unpleasant, so be sure to remove any unpleasant odors when cleaning. To eliminate unpleasant odors, sprinkle baking soda over the unfolded mattress. After about an hour, vacuum up all of the baking soda.

Step 3. Get rid of stains
If you notice stains on the sofa while cleaning, try removing them with a damp cloth, mild detergent and warm water. Don't overdo it with water, as too much moisture can lead to mold growth. Most stains can be removed with regular detergent and water.
Remember to test the cleaning solution on a small area of the sofa first to make sure the detergent won't cause discoloration or other damage

Step 4. Wipe and inspect the frame
When cleaning the sofa bed, you should also clean the frame. Remove the mattress and wipe the sofa frame with a commercially available cleaning solution. The metal frame should only be wiped with a damp cloth.
Make sure the solution will not harm the pull-out sofa by first applying it to a small area of the frame
Method 2 of 3: Removing stains

Step 1. Blot as much of the stain as possible
If the stain cannot be removed using conventional methods, try to remove as much liquid as possible from the stain first. Stains are best dealt with as they appear. If you spill any liquid on the sofa or your pet urinates on it, immediately apply paper towels or a sponge to the area. Press them against the stain to absorb as much liquid as possible.
Never rub the stain, just blot it (press and lift). If you start rubbing it, the stain will grow in size and seep into the fabric more

Step 2. Treat the mattress with vinegar solution
Mix 1: 1 white vinegar and water in a bowl or bucket. Pour enough solution over the stain to completely cover it.
- For urine stains, use an enzymatic cleaner.
- If there are mold or mildew stains on the mattress, mix equal parts water and rubbing alcohol and pour over the stain. This solution can also be used to protect against mold / mildew growth if the mattress becomes damp.

Step 3. Add baking soda and hydrogen peroxide
After treating the stain with vinegar solution, apply baking soda to it. Then, mix a quarter cup (60 ml) of 3% hydrogen peroxide with a teaspoon (5 ml) of dish soap. Apply this solution to the stain. Leave it on for 15 minutes.

Step 4. Blot the stain with a paper towel
After 15 minutes, blot the mattress again with a paper towel. Blot the stain until you have removed most of the vinegar, water, soap, and baking soda. After removing the cleaning solutions, the stain should also disappear.
If the stain still remains, contact a professional dry-cleaner of upholstered furniture

Step 5. Let the mattress dry
Do not use the mattress until it is completely dry. In the air, the mattress can dry within 24 hours. Use a hair dryer to speed up this process. Leave the mattress in the sun, if possible, so it dries faster.

Step 6. Vacuum the mattress
When the stain is dry, vacuum the mattress to remove any remaining baking soda. As a result, the mattress will be clean and will stop smelling.
Method 3 of 3: Keeping your mattress clean

Step 1. Slide the cover over the sofa bed
Buy a slipcover to keep your sofa bed clean. You can buy the cover online or at your local department store. The cover should protect the sofa bed from stains and spills. The cover will need to be washed several times a month.

Step 2. Ventilate the mattress from time to time
Do not leave the cover on the couch all the time. Remove the cover from the sofa an hour before cleaning to allow it to air a little.

Step 3. Don't put the mattress on the floor
Always use a sofa bed frame. The closer the mattress is to the floor, the more likely it is to get dirt and debris on it. If you put your mattress on the floor, you will need to clean it more often.

Step 4. Periodically flip the mattress to the other side
Turn the mattress over about once a month to prevent squeezing. This will prevent the packing from wearing out.
