That “hack” gets shared a lot, and it can work—but it’s a bit more limited (and harsher on surfaces) than it sounds.
Dishwasher tablets contain strong degreasers and alkaline cleaning agents, which is why they can cut through baked-on grease in an oven. People usually dampen the tablet and scrub directly on greasy areas or dissolve it in warm water and use it as a paste.
But a few important caveats:
- It’s abrasive/chemical-heavy: It can damage oven enamel or protective coatings if you scrub too hard.
- Not ideal for self-cleaning ovens: It can interfere with the coating or leave residue.
- Ventilation matters: The chemicals aren’t meant for food-contact surfaces in that way, so you’ll want to rinse extremely well and air it out.
If you want a safer “like new” result, these usually work better:
- Baking soda + water paste (leave overnight, then wipe)
- Vinegar spray after baking soda (for fizzing grease lift)
- Dedicated oven cleaner (designed for enamel safety)
So yes—dishwasher tablets can cut grease, but they’re more of a “last resort strong cleaner” than a true oven restoration trick.
If you want, tell me how dirty your oven is and I can suggest the safest method for that level of buildup.
