8 Clever Uses for Condenser Dryer Water

Reusing your condenser dryer water is an excellent way to conserve water. Whether you live in a drought-stricken area, in a place where water shortages are common, or you just want to help the planet, this is something you won’t regret looking into! Below, I have outlined 8 uses for condenser dryer water that are both functional and good for the planet.

1. Watering (Some) Plants

Your condenser dryer water can be used to water some of your plants. I say “some”, because the water that comes from your dryer is acidic from the detergent and the water vapor created during the drying process, and there are several plants this water is not suitable for.

Plants You Shouldn’t Water With Dryer Water

I suggest not using this water for any potted plants. The reason is that the acidic water would be entirely concentrated in the pot instead of spreading as it would in the soil of a garden. This would most likely result in the water killing your precious potted plants.

Furthermore, the minerals in water are good for plants. The condensing process in the dryer removes most of these minerals. So, potted plants who have limited access to soil minerals and alternative water sources, could “starve” on condenser dryer water alone.

Also, avoid watering any edible plants, such as fruits and vegetables that you proudly grow, with this water. Dryer water is not suitable for human consumption. Watering plants you intend to eat with dryer water might affect the plants’ growth as well as your health.

If you want to maximize the growth of your newly sprouting plants and seedlings, then stick to watering them with fresh water only. The acidic dryer water might kill them as they are not yet matured enough to withstand the change in acidity and the contaminants in the water.


You cannot use this water to water plants that need alkaline soil in order to thrive. Such plants include Lavender, Boston Ivy, and certain flowering shrubs.


Plants You Can Water With Dryer Water

You can still use your dryer water to water your grass or plants that are directly planted in open soil since there is enough surface area for the water to spread, and there is rain that can provide these plants with necessary nutrition that is not present in condenser water.

Notably hardy plants and established plants should also be fine when watered with dryer water.

2. Mopping the Floors

Another great way to utilize the dryer water is to mop your floors with it. There is no reason to worry about any excess detergent in the water as you will be adding other kinds of cleaning products to clean the floor regardless.

You may even be able to use less of your floor cleaner if you see the used water is still relatively soapy. On the other hand, you can also top it up with fresh water if you want to dilute the detergent further.

Sometimes the condenser dryer water can have some lint in it, which might appear on the floor while you are mopping it.

To avoid this but still reuse the water, you can simply filter it before using it. A filter paper (amazon link) or a fine-mesh sieve (amazon link) should do the trick. The filtered water will still be soapy, but you won’t have to sweep any lint away afterward.

3. Washing Outside Furniture

You can also use your condenser dryer water to clean your outside patio furniture. Outside furniture is usually made of durable materials such as steel, metal, or even plastic. This means the residual detergent left in the water won’t cause any damage to it.

You probably won’t even need to add more cleaning detergent to the bucket, as simply wiping down your furniture with the used water should get rid of any accumulated dust and dirt.

If you have any outdoor furniture with fabric components (such as cushion covers), remove those before you start cleaning. I would also avoid using this water on furniture made of softer materials such as straw or thin wood.

4. Use It in the Washing Machine

It might sound counter-productive, but a great way to reuse your dryer water instead of draining it outside is to put it to use in the washing machine. No, not as rinse water as that would only add more detergent to the already washed clothes.

Instead, use it in place of wash water. This way, your washing machine will be using less fresh water. The dryer water is suitable for cleaning your clothes as you add detergent to the wash water anyway.

The washing machine will then use fresh water during the rinse cycle, and your clothes will be as clean as usual.

Now, to make this work is no easy task. But it is not impossible, and those committed to water conservation won’t mind putting in some extra effort.

Some combined washer-dryer machines do have a setting for this (just consult your manual or contact the product provider). Otherwise, you can get in an experienced plumber to do the job for you as it involves moving some pipes here and there.

5. Flushing the Toilet

Another way to utilize the dryer water is to use it to flush your toilet. Simply drain the dryer water into a bucket or two and store it next to the toilet.

Once someone has used the toilet, they have two options. They can either pour the water directly into the cistern and then simply flush the toilet as normal or they can pour it into the toilet bowl.

Pouring it into the cistern is a great way to save water, but some cisterns can be quite tricky to open and heavy to lift.

In addition, you need to turn off the water supply to your toilet. Otherwise, your cistern will fill automatically, which would completely defeat the point. However, you should keep an eye on the cistern and ensure there is water in it at all times. If not, then the p-trap could become dry, and you don’t want that!

The alternative, pouring the bucket of water directly into the toilet bowl, should be done slowly to avoid spilling all over your floor (but hey, if you do, refer back to tip 2!).

Yes, this seems like quite the schlep, but if you really want to make a change, you need to put in the effort.

6. Washing Carpets

Carpets are typically hardy. After all, they are subjected to foot traffic, pets, spills, moving furniture, etc., so a little dryer water is not likely to fray or deteriorate the material.

The task of washing the carpets in your home involves filling up the automatic carpet machine with water and detergent (or a bucket with the same if you are doing it by hand). So, does it not make sense that simply using water that already has some soap in it will get the job done just as well?

You might need to add a little bit more detergent, depending on the state of your carpets. However, for your general cleaning, this water should suffice. You will only need to add fresh water if you notice that the soap is not being removed from your carpet efficiently enough.

Of course, just like with washing your floors, remove any lint through filtration to avoid having lint speckling your carpet—which is a nightmare to remove.

7. Cleaning Bath, Shower, Sink, and Toilet

A bathroom and its amenities are a high-traffic zone in any home. You can definitely use the potentially slightly soapy dryer water to your advantage and use it to wipe down your bath, shower, sink, or toilet.

When you clean the bathroom, your aim is to kill of bacteria and any molds that are trying to take hold. To achieve this, you typically add quite strong cleaning products to the water. So, having fresh water for the washing is not a priority; it just has to be clean, which dryer water will be if you keep your collection tank clean.

8. Washing out Garbage Cans

Ah, cleaning the garbage cans. A chore that nobody likes to do, but one that is vital in order to reduce odors and maintain overall hygiene. Garbage cans are typically full of germs and bacteria, so simply rinsing them out with water every once in a while will not clean them efficiently.

Get into the habit of collecting the dryer water in a bucket and washing your garbage can at least once a week (you will need to use a good soap or cleaning product with the dryer water!). Regular cleaning will limit the odor and reduce the chance of nasty bugs and critters making their home in there, feeding off last week’s leftover lasagna.

What About Use in Irons?

When I first started researching alternative uses for dryer water, one of the first things that cropped up was use in irons. Not all sources were in favor o the practice, but others said it was a brilliant solution to their steam iron problems.

I have not included this use in my list because there is too much conflicting information. You can read about the arguments for and against in Using Tumble Dryer Water in an Iron: Foolish or Genius?
