The fabric on the seat and backrest can be spot-cleaned with a damp cloth or sponge and mild detergent but should never be submerged in water or put in a washing machine. As for any other parts of the high chair, such as wheels, buckles, straps, or the tray, you should use a damp cloth with soap and warm water. Always remember to dry them completely before re-assembling the high chair.

Also, check the manufacturer’s instructions for specific cleaning instructions, as this may vary depending on the model of your high chair. It is advisable to clean your Cosco High Chair regularly by wiping down frequently touched areas like the seat, backrest, tray, and armrests to help ensure your child’s safety.  It is also important to disinfect surfaces in accordance with the manufacturer’s instructions.

Finally, never leave your high chair unattended, as it can cause accidents if not used correctly.  Keeping your Cosco High Chair clean will enable you to get the most use of it for years to come.  By following these steps, you will ensure that your high chair is safe and sanitary. 

Needed Materials:

Before you get started with the cleaning process, make sure you have all the necessary materials on hand. You will need:

A Damp Cloth or Sponge:

This is the most basic tool you will need for cleaning your Cosco High Chair. Use a damp cloth or sponge to wipe down all of the surfaces of the high chair.

Mild Detergent:

To remove any tough stains, use mild detergent on a damp cloth or sponge and gently scrub the affected areas. Make sure to rinse off any remaining soap residue before drying.

Warm Water:

Warm water is the best option for cleaning any high chair. It will help to remove dirt, grime, and food residue with ease without damaging any parts of your chair.

Disinfectant Spray or Wipes:

It is essential to disinfect your high chair regularly to eliminate any germs that may be lingering on the surface. You can use a disinfectant spray or wipes that are safe for your child’s age. Always follow the manufacturer’s instructions for proper use.

Soft Brush:

A soft brush is useful for getting into hard-to-reach areas of your high chair, such as between the seat and backrest or in crevices where food may get stuck. Make sure to use a gentle touch and not apply too much pressure that could damage the chair.


Before re-assembling your high chair, make sure all parts are completely dry. Use a towel to wipe down any wet areas or leftover moisture.

10 Methods on How to Clean Cosco Highchair

1. Wipe down with a Damp Cloth:

The most effective and efficient way to clean a Cosco highchair is to simply wipe it down with a damp cloth. This will remove any dirt, dust, or debris. Be sure to use only mild soap and warm water for this step. Avoid any harsh chemicals or abrasive cleaners. Although it may be tempting to use a power washer or steam cleaner, these methods should not be used as they can damage the highchair.

2. Vacuum the Chair:

Using an upholstery attachment, vacuum the seat and back of the highchair to remove any remaining dirt, dust, or debris. Be sure to move the vacuum slowly and in a circular motion for the best results.

Also, be sure to check the crevices of any folds in the cushioning for dirt. If your highchair has straps or buckles, you should also vacuum the hose to remove any dirt buildup. Once finished, dispose of the dirt and debris in an appropriate trash can.

3. Clean the Tray:

Remove and clean the tray of the Cosco highchair with warm, soapy water and a soft cloth or sponge. Rinse with more warm water and dry completely before replacing it on the chair. 

For really tough messes, you can use a mild detergent or baking soda paste. Also, make sure to clean all the crevices of the tray and remove any food particles or crumbs. If the tray is dishwasher safe, it can also be placed in the top rack of the dishwasher.

4. Sanitize with White Vinegar:

Pour white vinegar onto a clean rag and use it to sanitize all surfaces of your Cosco highchair, including its seat, back, arms, legs, and tray. This will help eliminate germs and bacteria that can accumulate on these surfaces over time.

Wipe down the surfaces until they are fully saturated with vinegar. Allow the vinegar to sit on the highchair for at least 10 minutes before wiping it off with a damp cloth. This will ensure that all of the bacteria and germs have been killed. Once you’re done, let the highchair air dry.

5. Disinfect with Rubbing Alcohol:

Use the same clean rag used for the white vinegar to rub alcohol on all surfaces of your Cosco highchair, including its seat, back, arms, and legs. The rubbing alcohol will help disinfect and kill any remaining germs or bacteria on these surfaces.

Remove as much rubbing alcohol as possible with a dry cloth, and let the highchair air dry before using it again. Be sure to keep a close eye on the highchair while cleaning with rubbing alcohol; too much can cause damage to paint and fabric.

6. Scrub with a Brush:

If there are stubborn stains that do not come off easily with a damp cloth or vacuum cleaner attachment, use a soft-bristled brush to scrub them away gently. Be sure to go in circular motions so as not to damage the fabric of the chair. If necessary, you can use a mild soap or detergent to help remove the stain. Once you have removed the stain, rinse off the chair with a damp cloth and allow it to dry before using it again.

7. Clean Harness Straps:

Remove the harness straps from around the body of your Cosco highchair and wash them separately in warm water with mild soap or a gentle detergent. Rinse the straps thoroughly and air-dry them before putting them back on the chair. 

Make sure they are completely dry before you put them back so that your baby won’t get a rash or skin irritation from the moisture.  If your straps are very dirty or stained, you may want to consider replacing them for safety and sanitation.

8. Clean the Wheels:

Use a damp cloth or brush to clean any dirt and debris from the wheels of your Cosco highchair. Be sure to dry them completely before replacing them on the chair. However, if the wheels are still not clean, you can use some mild soap and warm water to do a deeper cleaning.

Rinse them off with cold water and dry them thoroughly before reattaching them. Be sure to inspect all the wheels for any damage or rust. If there is any, take appropriate measures to fix it before putting the chair back together.

9. Air Dry:

Once all parts of your Cosco highchair have been cleaned and dried, allow it to air-dry for at least 30 minutes before using it again. This will help ensure that all surfaces are free from dirt and residue. It is important to thoroughly dry all parts of the highchair, including any straps, buckles, and other accessories. This will ensure that your child is safe and comfortable when using the highchair.

For best results, try to clean your Cosco highchair every few weeks or more frequently, depending on how often the chair is used. This will help keep it in top condition and ensure your child’s safety. Regular cleaning and maintenance of your highchair will also keep it looking fresh and will extend its lifespan.

10. Apply Protectant:

To protect your Cosco highchair from future staining, apply a fabric protector spray or wax-like beeswax once it has completely air-dried. This will help repel any dirt and debris in the future. To apply a fabric protector spray, hold the can at least 10-15 inches away from the highchair and spray it onto the surface in an even layer. To apply beeswax, use a soft cloth and rub the wax into the fabric in circular motions. When you are done, buff it off with a clean cloth.

Be sure to follow these steps carefully, and always use mild soaps or gentle detergents on all surfaces of the chair.

Do You Need to Use Professionals?

While cleaning your Cosco highchair yourself can be a cost-effective option, you may want to consider hiring professional cleaners if the chair is heavily stained or has not been cleaned in a long time. Professional cleaners have the tools and expertise to deep clean and disinfect the chair thoroughly, ensuring that it is safe for your child to use.

Additionally, professional cleaners may also offer services to repair any damage or wear and tear on your Cosco highchair, further extending its lifespan. It is important to weigh the cost of hiring professionals against the potential benefits and convenience they may provide. Ultimately, the decision to hire professionals is up to you and your specific cleaning needs.  So, consider all factors before making a decision.

How Much Will It Cost? DIY Vs. Professionals

Cleaning your Cosco highchair yourself will likely be more cost-effective than hiring professional cleaners. However, the cost of professional cleaning services can vary depending on factors such as location and the condition of the chair. It is best to research and compare prices from different cleaning companies before making a decision. You may also want to ask for recommendations from friends or family who have used professional cleaners in the past.

In terms of DIY costs, you will only need basic household supplies such as white vinegar, rubbing alcohol, mild soap or detergent, and a soft-bristled brush. These items are generally affordable and can be used for multiple cleaning sessions, making DIY cleaning a more budget-friendly option in the long run.
