Let’s talk about detergent bottles. Wonderful, adaptable detergent bottles.

Most people have one use for them — to hold laundry detergent. But if you look at the design of modern detergent bottles, they clearly have a life beyond the last drop of liquid goodness inside. All it takes is a little imagination.

In my previous post on reusing disposable items, I briefly touched on the detergent bottle. And in doing so, I uncovered a multitude of uses for this versatile bottle that is usually trashed or recycled the second it runs dry.

A quick tip before we get to the list — the design of detergent bottles is quite unfriendly for the consumer. If you use them as directed, you’ll be left with at least one or two extra loads in the bottle even though nothing is pouring out. There are ways to get to it, but in doing so you may have to render the bottle almost useless. However, depending on your method of extracting the precious liquid, you could still be left with a very useful hunk of plastic. (See also: 22 Ways to Reuse Paper)

1. Sharps (Needles) Disposer

According to Diabetes.org, over 8% of the US population is diabetic (PDF). That’s quite the statistic. A vast majority of those people require regular shots of insulin, and those needles, or sharps, must be disposed of safely. They sell sharps containers in the stores, and they run anywhere from a few bucks to several hundred dollars for a two-gallon size. But why bother spending any money? Take an empty detergent bottle, secure the lid to the base with strong tape, and cut a small slot in the top. You now have a safe place to keep your sharps. When it’s full, seal the slot and dispose of it safely (PDF).

2. Ice Melt Shaker

I used to keep my ice melt in an old cat litter container and used a scoop to sprinkle it on walkways and driveways. The laundry detergent bottle is even easier. Just fill one with ice melt and then do one of two things:

• Remove the lid and sprinkle liberally, or…
• Poke large holes in the lid and sprinkle, like a giant salt cellar

Either way works; it just depends how much ice you have and how much you want to put down on the floor.

3. Drip Irrigation

Clean your detergent bottle and fill to the top with water. Place it in the top of your plant pot, or next to plants in the garden, and punch a few very small holes in the bottom (plus one in the top if you want the water to flow more freely).

You now have a simple but effective tool for providing plants with a slow and steady source of water. This is very helpful if you’re going on vacation and don’t want your plants to perish in your absence. It’s also good if you simply want to remove a daily task from your agenda. Now, watering the plants can be done automatically; all you need to do is fill up the container when it’s empty.

4. A Lampshade

Seriously. There are plenty of pictures of detergent-bottle lamps demonstrating the various methods available to you for construction. Some simply require you to thoroughly wash your bottle, which includes removing the label, and then attaching to a lamp fitting. Others are much more elaborate. The lamps are unique, and if done right can look like art with a high dollar value.

5. Toddler Tool Box

I saw this one at a friend’s house, and he sent me the link to the original toddler tool box creator. If you have one of those huge detergent bottles and also have young kids, don’t throw it away. Follow these instructions to create a fun (and free) toolbox that your young one can carry all of his or her valuables, cars, dolls, or anything else in. And the grown-ups can use it too.

6. Watering Can

Hot on the heels of the ice melt shaker, you can also use your old detergent bottles as watering cans. The small ones are great for the younger kids, and the big ones work almost as well as the pricey ones from the hardware stores. Just wash your bottle thoroughly, then poke many small holes (a metal skewer is good for this) in the lid. Fill with water, tighten the lid, and you have a great watering can for nothing.

7. A Handy Scoop or Funnel

Don’t pay for a scoop again. Just cut your clean detergent bottle diagonally across the middle, and you have a sturdy scoop that can be used for all sorts of things. Make one for the cat litter, one for fertilizer, and even use one of the larger ones as a dustpan. You can also use a straight cut across the middle to create a funnel, which can be handy for pouring paint into smaller containers.  

8. Free Weights

Literally. The first set of weights I ever bought were light as a feather. When you took them home, you would fill them with sand and they became heavy enough to use in a workout. The same principle applies here. Fill your different sized detergent bottles with sand and you will have weights of varying sizes, which can be used like a kettle bell for strength training.  

9. Paint Storage

Paint cans are annoying. They have to be hammered shut, opened with a special tool or screwdriver, and the paint always drips down them. If you don’t get the lid on tight enough, you will be greeted with a can of thick or dried out paint when you next use it. Even a small amount of water loss from the can change the color and consistency. So, when you’ve got paint left in a can from a decorating job, pour it into a detergent bottle and screw the lid on tight. When you next come to decorate, you’ll have fresh, easily pourable paint with no drips. Make sure you put a little of the paint on the outside of the bottle to recognize it on the shelf.

10. A New Spin on Sandbags

A few people in my neighborhood have basketball hoops, and they weight them down with sandbags. You can create your own weights with sand and a detergent bottle, just like in the free weights tip. These can be used to hold anything down, such as tarps, tents, or sports nets, or used to add additional weight in your trunk in those tough winter driving months.

11. A Slug Trap

Worms are a gardener’s best friends. Slugs, alas, are not. They are a pest that can destroy your plants and vegetables. To make a simple slug trap with a detergent bottle, make a straight cut 2-3 inches from the bottom. Sink this base into the ground, ensuring the rim is level with the soil, and fill with bait (a little beer, or some water and yeast). You can also coat the inside walls of the base with a little liquid soap. The slugs will come in to feed, but cannot get back out.

12. Swimming Floats

This is about as easy at it gets. Clean the detergent bottles thoroughly, removing the labels. Then screw on the tops very tight. You now have cheap and effective floats to help the little ones in the pool.

13. Hand Washing Station

My grandpa, a keen gardener, used to do this with old plastic milk jugs; but it works just as well with detergent bottles. Clean them, fill with water, and leave them on your potting table or in your shed. Place some napkins and liquid soap nearby. When you’re ready to come in, you’ve got the convenience of a sink without the plumbing.

14. Feed the Birds

Tuppence a bag! Sorry, I love Mary Poppins. I also love birds, and I have a feeding station on the front lawn. You can create a good bird feeder from detergent bottles, and a little green or black spray paint can make them blend right in. First, cut holes in the sides of the jug, around 2-4 inches in diameter. If you want to provide perches, drill holes and push dowel rods through them. Puncture a few small holes in the base for water drainage. Then, hang from a tree or garden pole and fill with seed.

15. Piggy Bank

A penny saved is a penny earned. So don’t buy a piggy bank, use an old detergent bottle and use the money you saved as your first deposit. Simply clean out your bottle, screw the top on tight, and cut a slot just big enough for the largest coin to fit through. Have the kids paint it if you want, or spray-paint it yourself.

You can duct tape the lid onto the bottle to deter people from dipping into the fund. And if you want it to be really tough to open, apply some super glue around the spout and screw on the lid. The only way you can get it open now is to cut it open. When you do, if it’s full, you’ll have quite the spending spree to go on.
