Although Diono car seats have machine washable car seat covers, it’s still best to hand wash them.

As per Diono’s specific instructions, in the case of machine washing, the washing machine must not have an agitator to avoid damaging the seat cover.

However, the memory foam must not be machine-washed. So, if you’re going to machine wash the seat cover, gently pull the memory foam off the seat cover first.

Whether you’re hand washing or machine washing, make sure to use a mild detergent or soap and lukewarm water.

Also, avoid fabric softener, bleach, and other harsh cleaners.

For hand washing, prepare a basin filled with lukewarm water with some added mild detergent or soap and agitate them to create suds. Then, soak the seat cover in the suds for a few minutes.

After letting it soak, gently scrub it using a soft-bristled brush.

Finally, thoroughly rinse it with clean water, making sure no residue is left behind.

Step 6: Dry the Car Seat Cover


Diono car seat covers can be naturally air-dried or dried in the dryer. But the memory foam should only be air-dried.

Make sure to avoid wringing the seat cover before you dry it. But you can pat it dry with a towel.
