DIY oven cleaner paste

Mainly that it avoids harsh caustic chemicals and fumes while still cleaning effectively. Commercial sprays often use sodium hydroxide, which works fast but is corrosive, strong-smelling, and requires careful ventilation and gloves. A baking soda paste works more slowly but loosens the same baked-on grime through gentle alkaline and abrasive action, leaving no chemical smell in the appliance you cook in. It is also far cheaper, made from a single cupboard staple, which many people prefer for both safety and cost.

Several hours, or ideally overnight, since time is what does the work. The paste needs long contact to penetrate and soften the burnt-on residue, so the longer you leave it, within reason, the easier it wipes away. Rushing this is the main reason the method underperforms. Leaving it overnight is the most reliable approach for a grimy oven, after which the loosened residue comes off with a damp cloth and a vinegar spritz on any stubborn spots.

It helps lift the last stubborn residue at the wiping stage. When you spray white vinegar onto leftover baking soda, the two react and fizz, and this bubbling helps loosen any remaining grime so it wipes away cleanly. Most of the actual cleaning is already done by the soaking paste, but the vinegar finish is useful for the final wipe and for rinsing away the baking soda residue, leaving the surfaces clean rather than powdery.

It will, but may need repeating or a little extra effort. Severe, long-neglected buildup might require a second application, a longer soak, or some gentle scrubbing on the worst carbon deposits. The method is genuinely effective but gentler and slower than caustic sprays, so very heavy grime simply takes more time and patience rather than more harsh chemicals. For maintenance cleaning done semi-regularly, a single overnight treatment usually does the job comfortably.
