Mix coffee with vinegar: The reason why all women in France do this

It sounds like you're referencing one of those popular viral claims — something like:
"Mix coffee with vinegar: the trick all French women swear by."

Here’s the real scoop:

Mixing coffee with vinegar isn't a widespread, everyday habit among French women. However, coffee and vinegar together can be used for some clever cleaning tricks at home:

Deodorizing: Mixing leftover coffee grounds with vinegar can neutralize strong odors in places like the fridge or sink drains.

Cleaning: Vinegar is already a natural cleaner. If you add coffee grounds (which are mildly abrasive), it can help scrub grime off pots, pans, and even stubborn spots on countertops.

Natural Dye: Coffee can stain fabrics (and sometimes wood), so combining it with vinegar helps set the color if you’re making a natural brown dye.

👉 In short:
It’s more of a home cleaning or natural beauty hack than a beauty "secret" for women in France. It's not something they all do daily for their health or beauty — it's mainly a DIY trick for cleaning or odor control!
