That claim is not reliably true.
Putting an oven rack in a bag is usually part of a viral “hack,” but it doesn’t automatically clean the rack to “as good as new.”
What actually happens
- A bag might help trap moisture or cleaner against the rack.
- That can loosen some grease, especially light, fresh dirt.
- But it doesn’t remove baked-on carbon buildup by itself.
Why scrubbing is still needed
Oven rack grime is often:
- hardened grease
- baked food residue
- carbonized layers
Those don’t just dissolve fully without:
- soaking time
- a cleaning agent (baking soda, detergent, or oven cleaner)
- some physical wiping/scrubbing
Where the “hack” comes from
These videos usually:
- show already lightly dirty racks
- or pre-clean them before filming
- or exaggerate the “after” result
Bottom line
A bag can be a helper step, not a full replacement for cleaning. If something is heavily dirty, scrubbing (even light scrubbing) is still necessary.
If you want, I can give you a no-heavy-scrub method that actually works well depending on how dirty your rack is.
