There are different ways to clean the toys of germs. We recommend freezing because it kills germs. Germs and dust mites thrive in warm conditions, so a deep freeze kills them.
Place the Little Sport Star baby toy or the activity gym and play mat in a plastic bag. Tie it up. Squeeze out as much air around as you can. Put the plastic bag in the freezer and leave it overnight or for at least 3 hours.
It is not as efficient, but you can also clean our baby toys and activity gym and play mat with warm water and some anti-bacterial soap and let them sun dry. Of course, extended sun exposure may fade or change the look of the baby toys. If you insist on using a washing machine, make sure it is on a low heat.
