You might be knee-deep in Lysol wipes and sprays, but did you know that Lysol wasn’t always just a home cleaning brand?

Lysol manufacturer Lehn & Fink once marketed its antiseptic disinfectant as a vaginal douche, according to vintage advertisements from the early to mid-20th century.

Women, the ads suggest, were having marital problems because of feminine hygiene issues and genital odors that repulsed their husbands, and thus, they needed to clean themselves using Lysol.

But the full story is even wilder than that.

To back up a little, Lysol brand antiseptic disinfectant first appeared on the scene in 1889 as a way to help end a cholera epidemic in Germany. In 1918, ads touted it as an effective means to fight the flu virus during the influenza pandemic. Twelve years later, Lysol disinfectant liquid reached drug stores and hospitals, and in 1962, the company released an aerosol spray version.
