How To Clean Mattress Vomit?

After you have prepared all the necessary tools, it is time to clean the mattress vomit. This mission is quite simple, but it takes a lot of time. 

Please refer to the following steps to clean your mattress most effectively.

Step 1: Eliminate Vomit

Peeling blankets and bedsheets

Before cleaning the mattress, make sure you remove the sheets and other items. Then you can wash it yourself or put it in the washing machine and choose the high heat mode to get rid of the bacteria on the sheets. 

If other accessories have not come into contact with the vomit stains, you should wash them separately to avoid them spreading bacteria to each other.

Get rid of vomit

To start cleaning, you must first remove all the vomit stains from the surface of the bed, this is like using the dishwasher. You need to remove all garbage and leftovers before you put the bowl in the machine for the machine to work at its best.

Use an object with a certain hardness, such as a fork or spoon, or a softer thing as a towel to scrape off the solids on the bed. You should collect it in a separate bag and tie it up before putting it in the trash for safety.

Vomit absorbent

The vomit from the body of a person or dog has a mucus solution. Which liquid is straightforward to seep through the gas and spill onto the bed. So it would help if you tried this liquid with a dry cloth or paper plate.

If using cloth, you should get an old cloth so that you can throw it away as soon as you’re done using it. You certainly don’t want to reuse a material filled with odors and bacteria for other things. 

In addition, you should note that it is absorbent; press the fabric down so that it absorbs all the liquid. Some people habitually wipe or rub, causing bacteria to spread to the surrounding area

Step 2: Deodorant

The vomit from a mattress consists of many finished products, creating a rather unpleasant odor. 

Even if you clean and find your bed white again, there will still be odors if not appropriately handled. So please follow the following way with baking soda to remove the smell completely.

Sprinkle baking soda on the vomit area

Blotting the liquid with a paper plate will only absorb some, and the bold pad will still be moist. So you need to suck out the remaining water in the bed by using baking soda. Pour the flour over the wet part; baking soda is an effective tool to help you absorb moisture and remove residual odors.

Let the dough rise for 8 hours or overnight

Baking soda takes time to work and absorbs any remaining liquid. So you need to leave it on the surface for at least 8 hours until they form blocks and dry thoroughly.

It is best not to affect the bed but to find another place to sleep temporarily. However, if you must lie on the bed, you can also cover the baking soda with a paper towel.

Use a vacuum cleaner to clean the baking soda residue

After sucking all the liquid left on the mattress, baking soda will have the phenomenon of clumps. You can use a vacuum cleaner to remove this salt.

However, to avoid clogging the washing machine and make the cleaning vomit smell process more manageable, you should first use rubber gloves to remove the big salt lumps and harsh chemicals.

After vacuuming the salt on the bed, you need to clean the vacuum cleaner carefully and the garbage bag to avoid bacteria growth. You should also choose the right vacuum cleaner head and hose for the best cleaning effect.

Some alternative deodorants

Another method that can replace baking soda to remove odors is rubbing alcohol. The property of alcohol is volatile, so when you spray it on a smelly area, it mixes with the odor molecules to blow them away and spread them out.

If you use rubbing alcohol, you won’t need to use a vacuum cleaner; just let them evaporate entirely on their own. In addition, alcohol also can help clean bacteria and disinfect them.

Step 3: Clean Stains And Disinfect

Although clean vomit from a mattress is only a transparent solution, it will also leave stains and yellow stains on the bed when exposed to the air. These stains also contain many harmful bacteria, so you need to properly treat the color and disinfect it with a spray bottle.

White vinegar solution is quite acidic, removing and whitening yellow stains on mattresses. However, using only vinegar can cause excessive corrosion of the bed surface, causing the opposite effect. 

So, you need to use an equal amount of warm white water to dilute the vinegar solution. If you feel that the stain has been around for a long time, you can add a little laundry soap to the above explanation for a better cleaning effect.

Step 4: Dry

The last but crucial and time-consuming step is to let your bed dry completely before using it. If the bed is still wet, it is easy to cause mold and degrade your mattress.

In case your mattress is of several layers, such as cotton or fleece, and you do not let it dry completely, it is easy to cause the mattress to deflate during use.

Depending on the weather, you can let the mattress dry entirely naturally. However, this process can take 6-8 hours. You can also use a fan or dryer to dry the outdoors to shorten the time it takes to dry the mattress. 

If you use a dryer, keep it about 8-19 inches from the bed to be safe.
