Never mix chemicals or cleaning agents with the anticipation that they will do a better cleaning job unless you are sure that they will interact safely. Mixing incompatible substances could result in a release of heat accompanied by violent boiling and splattering (e.g., via the addition of water to concentrated mineral acids), the release of toxic or deadly gases (e.g., mixing acids with bleaches or cleansers) or combustion (e.g., mixing acids with organic solvents).

Latex paint has many uses. Homeowners prefer it its ease of use and can be cleaned up with water. After the home project is finished, there is usually paint left over. It is recommended to keep it if you need extra paint for patches and touch ups. There comes the question how much the latex paint will last. If the container is not opened, the paint can last more than three years. However, several factors define how long the latex will last in the can after it has been opened.
