Needless to say, it didn't work so well, and lots of women ended up with vaginal burns and lots of other medical problems from applying Lysol to their lady bits.

Without further ado, I present some of Lysol's ads:

ETA: these are 4 of the 8 ads I looked at personally, from 1926-1934, but Lysol contraceptive advertising continued through the 1950s.
