I've read that water-based paints are easier to clean up than oil-based finishes. How do I know whether I'm buying a water-based or an oil-based paint?

About 80 percent of paint sold today is water-based; the rest is oil-based. Oil-based paint is considered more hazardous than water-based paint because the solvents used to make it are toxic and flammable. Note that you can recycle both types.

Water-based paint often has the word "latex" as part of the product name. Ingredients include water and ethylene or propylene glycol. Water is indicated for cleanup.

Oil-based paint often has the word "alkyd" as part of the product name, and the label will indicate "caution" and "flammable" or "combustible." Ingredients include petroleum distillates or mineral spirits. Cleanup method indicates the use of paint thinner, mineral spirits, or turpentine.
