2. Store other hazardous materials (drain opener, rust and lime removers, oven cleaners) in their original containers and out of reach of children, making sure that the labels are clearly visible. Choose well-ventilated storage areas for materials that might produce vapors and fumes, and never store in the same area as a gas water heater. Keep them away from food, including pet food. Contamination can occur even if the chemical is not in direct contact with the food.
Half-used paint cans turn useless fast when air sneaks in, rims crust over, and nobody remembers which beige belonged in the hallway. A few simple storage habits keep leftover paint workable longer and make touch-ups much easier later (because guessing the right wall color never ends well).
These tricks cost next to nothing compared to replacing even a single quart of interior paint, which commonly runs around $20 or more at big-box stores. Making a better storage system yourself also lets you control labeling, limit repeated air exposure, and keep small touch-up amounts handy without reopening the main can.
You only need a short list of supplies for these paint-saving habits: leftover paint, wax paper or aluminum foil, and a clean Mason jar for small touch-up portions. A rubber mallet, permanent marker, and a rag handle the sealing and labeling, while the same common-sense approach also helps you store gasoline and other household hazardous materials more carefully.

Materials You’ll Need
- Leftover paint
- Wax paper or aluminum foil
- Permanent marker
- Clean Mason jar
- Gasoline in its proper storage container
- Other hazardous materials such as drain opener, rust and lime removers, and oven cleaners in their original containers
Tools/Equipment
- Rubber mallet
- Rag or cloth for wiping the rim of the paint can
How to Store Paint and Hazardous Materials
- Prevent air from contacting the paint surface when resealing the can. Cut a circle of wax paper or aluminum foil and float it on top of the remaining paint.
- Wipe down the rim of the can, then put the lid on very tightly by tapping it closed with a rubber mallet.
- Brush a line of paint on the can’s exterior to show both the level remaining and the paint color.
- Jot a note on the side with a permanent marker that tells you when and where you bought it and which room it’s used in.
- Pour a small portion of any leftover paint into a Mason jar for touch-ups so you will not have to open and reseal the main container every time.
- Label the Mason jar with the paint color or mixing formula, the room it’s used in, and the date.
- Keep gasoline in a tightly sealed, prominently labeled container in a cool location separate from your residence. A detached garage or a storage building is far preferable to a basement or an attached porch.
- Store other hazardous materials in their original containers and out of reach of children, making sure the labels are clearly visible.
- Choose well-ventilated storage areas for materials that might produce vapors and fumes, and never store them in the same area as a gas water heater.
- Keep hazardous materials away from food, including pet food. Contamination can occur even if the chemical is not in direct contact with the food.
- Store chemicals out of direct sunlight because some can break down when exposed to light and can lose their potency.
- Keep chemicals at room temperature. Some products can release vapors if they sit in high heat, so follow the label and keep them tightly closed in their original containers. The EPA also recommends keeping household hazardous products in their original containers with labels intact rather than transferring them to food containers or unlabeled jars: Household Hazardous Waste guidance.
Helpful Storage Tips
- Using a small Mason jar for touch-ups helps protect the main can from repeated opening and resealing.
- Writing the room name right on the can saves you from hunting through old notes later.
- A visible paint stripe on the outside of the can makes color matching faster at a glance.
- If you’re getting ready for a painting project, these rookie paint mistakes to avoid can help you waste less paint in the first place.

Safety Information
WARNING:
Avoid storing paint in extreme heat or cold. Either can damage the paint, and extreme heat plus oil based paint could lead to a fire.
Never use a food or beverage container for storing hazardous materials. The resulting mistaken identity could be fatal.
Check container labels carefully before discarding. Most labels will list specific instructions. Never burn or bury containers that once held hazardous materials.

Frequently Asked Questions about Tips-n-Tricks for Extending Paint Life During Storage
Yes, for a small touch-up portion. Keep the main paint in its original can, then pour a little into a clean Mason jar for easy access. Label the jar with the paint color or mixing formula, the room it belongs to, and the date so you know exactly what it is later.
It helps limit air contact at the paint surface when you reseal the can. Less air contact means less chance of a skin forming across the top, which saves you from digging chunks out of the can next time.
Write down when and where you bought the paint and which room you used it in. A stripe of the actual paint on the outside of the can also shows the color and gives you a quick visual on how much is left.
No. Store gasoline in a tightly sealed, clearly labeled container in a cool location separate from your residence, such as a detached garage or storage building. A basement or attached porch is a poor choice because vapors can spread quickly.
Don’t do that. Keep hazardous materials in their original containers with the labels clearly visible. That avoids mix-ups and keeps the product instructions and warnings right where you need them.
Because contamination can happen even without direct contact. Keep those products well away from food and pet food so fumes, spills, or residue don’t create a problem you can’t see.
Yes. Some chemicals can break down in direct sunlight and lose potency, which is why a room-temperature storage spot out of direct light is the better choice.
Yes. Extreme heat or cold can damage paint during storage. Heat also creates an added fire concern with oil based paint, so skip sheds, trunks, or other places that swing wildly in temperature.
No. Check the product label before discarding any container that held hazardous material, and never burn or bury it. The label usually gives the disposal direction you need.
