Here at Diono we design and build all of our car seats to last the distance.

But along the way, adventures can get messy and your little one might have second thoughts about keeping their car seat spotless. So we’ll take you through some of our top tips to help you freshen up your Diono car seat ready for the next family road trip!
Before you get started…

You’ll need to make sure you have enough time for a thorough clean and that you won’t be needing your child’s car seat anytime soon as you’ll have to factor in some drying time after washing.

If you don’t have a Diono car seat, please refer to your manufacturer’s instruction manual for cleaning instructions.

Here’s what you’ll need: 

  • Warm water
  • Clean towel
  • Wash cloth
  • Mild soap
  • Vacuum
  • Air duster – such as “canned air” used to clean a computer keyboard
  • Baking soda
  • Soft bristled brush


Step 1: Remove the car seat from the car 

  • This is where you’ll probably need the vacuum to clean the inside of your car where your child’s car seat was sitting. Good luck! You’ll probably find lots of goodies under there that they have been storing just for you.
  • If you notice a lot of debris and liquid underneath you can always look at car seat protectors to place underneath your child’s car seat. Just make sure it’s made by the same company that makes your car seat, or that it’s specifically approved for use with your car seat.
  • Once you’ve removed the car seat flip it over and remove any debris from the bottom with a soft bristled brush.
  • You can also use an air duster (like a keyboard cleaner) to remove crumbs from the nooks and crannies – like the center buckle and cam lock.
  • Fold the seat and look for debris in the folding mechanism and locking bolts. Clean these with water and a damp cloth only, and towel dry to prevent rust from forming. Do not use any bleach, harsh soaps, detergents, solvents or abrasive cleaners.



Step 2: Cleaning the Cover

  • Remove the memory foam. Do NOT machine wash. Hand wash or purchase a replacement if needed from our website.
  • Remove the car seat cover and hand wash or machine wash only in a front-loading machine or top loader with no agitator, using a mild soap or detergent.
  • Do not use bleach or hot water to wash the cover.
  • Line dry or air dry in a dryer with a fluff or “no heat” setting.

Step 3: Cleaning the plastic shell

  • Clean with a damp cloth only. Wet the cloth with warm water and mild soap and wring thoroughly so it is not dripping water. Wipe the shell and towel dry.
  • Make sure that all debris has been removed and everything is dry and that all mechanisms are working properly.

Step 4: Cleaning the harness straps

  • Clean with a damp cloth only. Wet the cloth with warm water and mild soap and wring thoroughly so it is not dripping water. Wipe the straps clean. Do not saturate or soak the straps.
  • To remove odor from the straps, make a solution using 4 tablespoons of baking soda and one quart of warm water. Dampen a cloth with the solution and wring so it is not dripping. Wipe the straps and allow to dry. Repeat if necessary.
  • If your straps are so soiled that you can’t keep using them you can also order replacement straps for your car seat.

Step 5: Cleaning the harness adjuster

  • Check the harness adjuster for cleanliness and proper functioning. It should spring back immediately when lifted. If necessary, remove debris with a soft bristled brush.
  • Clean with water and a damp cloth only. Wring the cloth so it is not dripping water.
  • ONLY use water to clean.
  • Towel dry

Step 6: Cleaning harness buckle

  • Remove center buckle from car seat.
  • Rinse the buckle thoroughly in mildly hot water or soak overnight to loosen dried liquid and hardened food debris. Do NOT get the buckle strap wet. Carefully rinse ONLY the buckle.
  • Allow to dry thoroughly.
  • Confirm proper buckle functioning.
  • Fasten and un-fasten both tongues. If you don’t hear the “click” repeat the process until you do. You can also order a replacement for your buckle if it’s not working or is full of debris.

Want to go the extra mile? Here’s some extra tips!

  • When you’re taking things apart, especially the harness straps, snap a photo or two so you don’t forget where things go.
  • An air duster keyboard cleaner comes in handy for those nooks and crannies.
  • Always refer to your car seat manual.
  • Use an approved seat protector under the car seat to keep your car from getting messy.
