Worst oven cleaner

CAUSTIC,WEAR MASK,GLOVES .IT WILL NOT WORK AND REMOVES FINISH. I BOUGHT IT AT DOLLERAMA. I SHOULD HAVE BOUGHT EASY OFF FUME FREE MAX. IT REMOVED THE FINISH FROM MY TOASTER OVEN. MY FULL SIZED OVEN AFTER TWO TREATMENTS LOOKED PRETTY MUCH THE SAME. I DO NOT RECCOMEND ANYONE USE THIS CRAP.
