How to Properly Apply Baking Soda on Carpet

Applying baking soda to your carpet is a straightforward process, but proper technique ensures maximum effectiveness and prevents any unintended damage. Start by thoroughly vacuuming the carpet to remove loose dirt and debris, allowing the baking soda to penetrate deeper.

Sprinkle the baking soda evenly across the carpet surface. For best results, use a fine mesh sieve or shaker to distribute it uniformly, avoiding clumps that might be difficult to remove later. Focus on areas with odors or stains, but don’t neglect the surrounding carpet to maintain overall freshness.

Allow the baking soda to sit for at least 15 minutes, though leaving it for several hours or overnight is preferable for stubborn odors. During this time, the baking soda will absorb moisture and odors from the carpet fibers. After the waiting period, vacuum the carpet thoroughly to remove all the baking soda residue.

Avoid using wet or damp baking soda as it can cause clumping and may be harder to remove, potentially leaving a residue in the carpet fibers.

Benefits of Using Baking Soda on Carpets

Baking soda offers several advantages when used on carpets, making it a popular household remedy:
