SMELLS IN WASHING MACHINES,
Verified Purchase(What is this?)
This review is from: Oust Dishwasher & Washing Machine Descaler (Misc.)
I used this product as the instructions suggested, but the smell in my washing machine was still there. I dosed it again with the second packet, but this time set the machine to wash at 90 degrees (not 60 degrees as the instructions stated). This time the smell was gone.
It worked to some degree, but would try another similar product next time.
