Using this oven door seal is easy. First, measure your oven's size. Then, cut the 2 - metre long seal into 3 pieces as needed. Fit the corner pieces and end hooks onto the seal. Hook the seal into the holes in your oven's surround. Note that this seal has square corners, so it may not fit ovens with rounded - corner doors. To maintain it, clean the seal regularly with a mild detergent and a soft cloth. This will keep it in good condition and ensure it works well for a long time.
