Liquid dish soap acts as a surfactant, breaking the surface tension of water and helping to lift oils and dirt so they can be easily rinsed away.

Mix equal parts of warm water and white vinegar in a spray bottle, then add a small squirt of liquid dish soap to the blend. Shake the bottle gently to incorporate the soap without creating an excessive amount of suds.
