it make excellent rice , I 'll give it that . but after 3 year of relatively light use -lrb- it spend 8 month of that time in storage while I be search for a permanent job -rrb- , the bottom be flake . not scratch , actively flake . I use the scoop provide and most of the time , I just wipe the pot clean . occasionally , I use dish soap -lrb- chemical-free -rrb- and a non-abrasive scour pad when starchy residue build up . it make excellent rice and porridge , but now I be look at drop another $ 100 + on a appliance when it should have last longer . one of my asian friend be still use she mom 's first Zojirushi and it be 20 year old ! I absolutely can not recommend this rice cooker .
