Effectively Reusing Dryer Water
The water from the dryer contains little lime, making it seem ideal for household use. However, it’s important to remember that this water comes from washed laundry. Traces of detergent and fabric softener, textile fibers, or fragrances may also be present in the water, as explained by “Stiftung Warentest,” a German consumer organization.
Soaking Clothes
Stubborn stains can be best removed from clothing by soaking them in a water bath before washing in the machine. Dryer water is suitable for this purpose. Any detergent residues are not a problem here. Not only is their function to clean laundry, but they will also be washed out during the machine wash.

Cleaning Water
Another option is to use the water for cleaning the home. Specifically, you can benefit from the nearly lime-free water when cleaning windows. Less lime means fewer lime marks and streaks on the glass.
Additionally, you can use the water for mopping. Add the desired cleaning agent to the dryer water and clean tiles and laminate as usual.
Where Not to Use Dryer Water
The use of dryer water also has its limits. When in doubt, it’s better to pour it down the drain than to risk causing damage in the household.
Irons
Lime-free water is ideal for ironing. However, it would be misleading to use the condensate water from the dryer for the iron. Due to possible residues like surfactants and fine lint, iron manufacturers advise against it. The fine nozzles of the devices could become clogged. The heating elements could also suffer, significantly reducing ironing performance. Use dryer water for steam ironing only if the manual allows it.
Watering Plants
Excess water is often quickly poured into the nearest flowerpot. If it’s the condensate from a dryer, it’s best to avoid this. The reason: The water can harm the plants. This is also due to possible lint and detergent residues.
