I Left Baking Soda on Tile Grout Overnight and Didn’t Expect This
Baking soda works on grout not through scrubbing force but through overnight chemical action that neutralizes trapped oils, soaps, and acids causing discoloration and odor. Applied as a paste and left untouched until morning, it draws residue from pores so it releases with a single wipe, and the grout then resists moisture absorption and dirt accumulation in ways that previous scrubbing methods never achieved. The key insight is that time, not friction, allows baking soda to alter the grout's surface environment permanently rather than just masking stains temporarily.
