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 apply to rub alcohol to 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. These ten methods can be used to clean your Cosco highchair and keep it looking like new for years to come.

Be sure to follow these steps carefully, and always use mild soaps or gentle detergents on all surfaces of the chair. With proper care and maintenance, you can enjoy your Cosco highchair for many meals to come!

Can You Wash a High Chair Cover?

Yes, high chair covers are made to be washable and can generally be washed in a washing machine. Many covers also come with instructions on how to best clean them. Generally, high chair covers should be washed in cold water using a mild detergent and allowed to air dry.

It’s also important not to use fabric softener when washing the cover as this can have an adverse effect on the material of the cover. If there are spots or stains that need extra attention, spot clean with a cleaning solution recommended for use on baby items.

Make sure to follow any specific instructions provided by the manufacturer of your high chair cover as well as any safety warnings. After washing and drying, it’s also important to check if any buckles or straps need tightening and that all hook-and-loop fasteners are still secure before putting the cover back on your high chair.


That’s it! With these simple steps on how to clean cosco highchair, you can quickly and easily clean your Cosco highchair. No more worrying about spills or crumbs – your child can eat happily and mess-free. It is important to clean it regularly.
