An explosion in the washing machine sounds absurd, but it is actually possible. Incorrect handling of certain detergents or textiles can cause gases to develop that can become dangerous. Here you can find out what causes this phenomenon and how to avoid this danger.
Which cleaning agents are dangerous?
The greatest danger to the washing machine comes from solvent-based cleaners such as stain removers, turpentine, white spirit or decolorizers. These products contain substances that volatilize at high temperatures and release gases. If pre-treated clothing is put directly into the washing machine, these Vapors accumulate in the drum and form an explosive gas-air mixture.
According to Maria Beltran, press spokeswoman for Robert Bosch Haushaltsgeräte GmbH, this is where the real danger lies: “Gases that concentrate in a confined space in the washing drum can react with the smallest sparks from the electronics.” Normally, such Sparks are harmless, but if they come into contact with a high concentration of gas, this can lead to a detonation.
Explosion hazard in the washing machine: these are the causes
The closed washing drum offers little space for escaping gases. Vapors from textiles that have been pre-treated with solvents accumulate. During the washing process, the Friction of the drum and the motor ensure that tiny sparks are produced – normally not a problem. However, in combination with a large quantity of flammable gases, this can lead to a dangerous explosion.
This is particularly problematic with textiles that are heavily contaminated with stain removers or chemicals. However, even with seemingly minor residues, for example after cleaning grease or oil stains with white spirit, the corresponding gas formation can be sufficient to damage a washing machine.
How you can avoid the danger
If you want to pre-treat textiles with solvent-based cleaners, you should never put them straight into the washing machine afterwards. Instead, it is recommended that you first thorough hand wash with plenty of water to remove as much of the chemicals as possible. Only when the smell of solvents is no longer perceptible can you put the garments in the machine.
Alternatively, there are now special stain removers that without solvents and are significantly safer. Many brands offer ecological forms that are effective but harmless. Check the packaging to see if the product is solvent-free.
Another safety measure: wash such pre-treated textiles separatelyto reduce the risk of contaminating other items of laundry.
Explosion hazard even in the dryer
Incidentally, the danger does not end in the washing machine. Flammable gases can also have an explosive effect in the dryer. It is particularly critical when treated textiles are washed together with synthetic materials should be dried. Plastics and foams increase the risk of fire as they can melt at high temperatures. Anyone wishing to dry pre-treated clothing should therefore ensure that all residues have been thoroughly removed and that the textiles have been fully aired.

Safety first
Although an explosion in the washing machine remains an unusual exception, it still pays to be careful. When pretreating textiles, avoid using solvent-based detergents if possible or rinse the garments thoroughly before putting them in the machine. After all, your safety – and the service life of your washing machine – comes first.
