Pizza Stone 4 "Great for cooking, but hard to clean" yanqi 25 June 2014 It's an amazing product for cooking pizza as it heats up so quickly and stays hot for a long time, but because of this, be aware to remove the pizza quickly to avoid overcooking. The stone is very difficult to clean as it's not recommended to use water or soap, so there's always crust left. A note from the team Thank you for placing a review. We'd recommend the stone is brushed as soon as the pizza is removed to clean it. We'll be in touch shortly.
