Storing your paint stripper properly will help it last longer and remain effective over time. If you don’t store your paint stripper in the correct manner, it can have serious consequences for the stripper and for your own health. Over time, improperly stored paint stripper will dry out and turn to sludge. This can’t be used, both because it’s more difficult and because it will have lost its effectiveness. Additionally, it will produce harmful fumes that can cause serious health problems if inhaled. To store your paint stripper correctly, the first thing you need to do is make sure it’s sealed tightly. Keep it in its original container, clearly labeled, and ensure that the lid is secure and tight. If the lid is damaged and leaves a slight gap, you can use tape to form a seal and prevent fumes from leaking out. If the container is now unusable (due to a crack, hole, or some other form of damage), you’ll have to find a new one. Don’t put the paint stripper in a different chemical’s bottle, even if you’ve cleaned it first. Mixing chemicals is extremely dangerous and residue can remain on a bottle even if you’ve washed it. Make sure the container you’re transferring the paint stripper to is safe for storing chemicals. Only use glass, metal, or plastic containers that won’t react with the chemicals, and have a tightly sealed lid that will keep fumes inside. Label the new container clearly so you know exactly what’s in it, to avoid any possible mistakes or accidents. Keep it in a cool, dry place out of direct sunlight and away from any heat sources. A tool shed or cupboard is ideal, and keep it on a shelf so it’s out of reach of children and pets.
