Burn marks on hobs are a nuisance. Ceramic hobs are most prone to burn marks, and are often the hardest to clean. Grease and food often become burnt onto the hob if they are not cleaned up promptly. Make the hob look new by cleaning it carefully and following the right precautions.
Remove heating coils from an electric stove, and the metal grills from gas stoves. Cover the gas elements with newspapers to avoid getting any chemicals in them.
Combine 1 part lemon juice with 1 part distilled vinegar. Place these in a spray bottle, and shake until mixed well.
Spray the solution onto the burnt grease. Let it set for 10 minutes, and then scrub the area with a moist washcloth. If the burn mark still appears, try another method.
Dampen the area with a wet cloth. Sprinkle a thin layer of baking soda on the burnt area. Allow the baking soda to set for five minutes. Use a sponge to remove the burn mark. If you still notice the mark, use a more aggressive method.
Moisten a steel wool pad filled with soap. Scrub the burnt area with the pad to remove the burn mark. Rinse the steel wool pad between scrubbings. Do not use steel wool pads on ceramic hobs; instead, use a commercial cleaning product designed specifically for these hobs.
