If you do not plan on using extra paint around your space, please be sure to dispose of it properly to protect our environment. Check the label on the can to see if the paint you want to get rid of is latex or oil/solvent based.
Most household paint used these days is latex based. To dispose of latex based paint simply leave the lid off (away from pets or children) so the remainder dries up. Alternatively, you can add kitty litter to the can. The kitty litter will soak up the remaining paint and solidify. Once the latex paint is dry you can dispose of it with your household trash.
However, if you have oil or solvent based paint, stain or other household toxins, you will need to dispose of these properly at a collection site in your community. In Washtenaw County, Michigan, there is a collection site for residents on Zeeb Road just north of I94 (see photo above). From April through November 2012, the home toxins collections center is open from 9 a.m. to 12 noon the first three Saturdays of every month (excluding holidays). For more information in Washtenaw County, click on the Home Toxins Reduction Program.
If you have other common household items that you are ready to part with, but are not sure what to do with, please feel free to contact me for some ideas.
