Suddenly my charger won't fit into the airpods case. I used a toothpick to clean it out and it doesn't seem to be anything in there. It's like the charger only goes half way in and gets pushed out. It has worked for a year perfectly.

Hello cyclone20,

Welcome to Apple Support Communities. 

We don’t recommend using a toothpick to clean your AirPods. we recommend the steps as listed here to clean your AirPods case: How to clean your AirPods, AirPods Pro, AirPods Max, and EarPods - Apple Support

Clean the charging case with a soft, dry, lint-free cloth. If necessary, you can slightly dampen the cloth with isopropyl alcohol. Allow the charging case to dry. Make sure not to get any liquid in the charging ports. Here are a few more guidelines:

• Remove any debris from the Lightning connector with a clean, dry, soft-bristled brush.
• Don't use abrasive materials to clean the charging case.
• To avoid damaging the metal contacts, don't put anything in the charging ports.

Take care.
