A soapy taste can be caused by many different contaminants on the way into your glass. So in order to get to the root cause of the soapy taste in your water, we’ll need to eliminate the other potential causes.
The most common causes of soap taste in your water
- Contamination. A contaminated cup or dish that hasn’t been cleaned properly is the most likely occurrence if the tap water is tasting a little bit funny. You can test this by properly rinsing the cup and trying again.
- Medications. Specifically, Telavancin, an antibiotic used to treat skin infections, bacterial pneumonia, and staph infections as a side effect, causes a soapy taste in the mouth.
- Genetics. Some foods like coriander affect people with a mutation in their OR6A2 gene, which causes them to taste soap when ingested.
- Backflow from appliances. If you experience a strong antiseptic smell or flavor in your water, you may be getting backflow from your washing machine or dishwasher.
How to fix a soapy taste in your water
Fortunately, for the majority of instances of a soapy taste in your water, the contamination occurs outside of the water supply (other than any backflow issues). This means you don’t need expensive filtration systems to fix a soapy taste, however, you can use an active carbon filter at the tap or in a jug to improve the taste if you are unable to identify the soap source.
