What does Dawn soap do to concrete?
Dawn dish soap is an effective, gentle cleaner for concrete surfaces when used correctly for routine maintenance. Because it is formulated to break down grease, oil, and organic grime, mixing a few drops of Dawn with warm water allows it to penetrate porous concrete pores and lift stubborn stains like food spills or light automotive grease. However, users must rinse the surface thoroughly with clean water; leaving soap residue behind can dry into a slippery film that attracts fresh dirt. While safe for occasional washing, Dawn should not be used as an aggressive acid wash or heavy-duty stripper, as it will not remove deep-set rust, efflorescence, or old stubborn paint layers from concrete slabs.
