That claim is a popular cleaning tip, but it’s a bit misleading.
A dishwasher tablet can help clean an oven, especially baked-on grease, but it’s not a magic solution and should be used carefully.
A safer approach is:
- Put on rubber gloves.
- Dip a dishwasher tablet in warm water (don’t let it dissolve completely).
- Gently rub greasy areas of the oven door or interior with the tablet.
- Wipe away the loosened grime with a damp cloth.
- Rinse thoroughly to remove any detergent residue.
Keep in mind:
- Don’t use this method on self-cleaning oven coatings, aluminum surfaces, or delicate finishes, as the tablet can be abrasive.
- Avoid scrubbing the oven’s heating elements.
- Never leave dishwasher detergent residue behind, as it can produce unpleasant fumes when the oven is heated.
So, while a dishwasher tablet can be effective for some ovens, it won’t necessarily make every oven “like new,” and it’s important to use it on compatible surfaces and rinse well afterward.
