We have a Fisher Price Booster Seat / High Chair, the kind that just straps onto a regular chair. That thing was DISGUSTING and I could never get the straps clean especially.

In a last ditch effort to get it clean, I just put the entire chair in the dishwasher and it came out looking BRAND new! It's amazing, the straps are sparkling for the first time since we bought it

Just wanted to share this in case anyone else has a super gross seat!
