An indu+ Teppanyaki cooking plate can be cleaned in two shakes. After frying, whilst the plate is still hot, pour ice cubes or fizzy water onto the cooking plate. That will detach any bits that have stuck.
Pat dry with kitchen roll and then you can easily clean the plate with detergent and a scouring pad ready for next time. Please note: use the scouring pad in the direction that the stainless steel is brushed. So horizontally.
