We've had this high chair for 8+ years now, and it has been great except impossible to clean (besides the tray), and so usually very super dirty all around the frame. Today I found a brilliant discovery though! I set it in the kids bath and turned on the hot shower then left it for 5-10 minutes. When I got back all it needed was about 3 minutes of wiping down the edges and it looked amazing! Hooray for a clean high chair once again!
