Looking for a natural solution for dirt? Reach for these gentle products the next time messes happen.

For stains: Use baking soda. Sprinkle it on the stain until completely covered; spray with water. When baking soda is absorbed, wipe clean with a cloth.

For mold, bacteria and grease: Use vinegar. Fill a spray bottle with distilled white vinegar. Saturate the affected area and then simply let the vinegar evaporate.

For soot, wax and oil: Use washing soda (sodium carbonate) on stone or glass. A cousin to baking soda, it can be found in the detergent aisle. Make a thick paste with 1/4 cup of soda and water. Cover stain and let it set for an hour; scrub.
