That's not how you're meant to clean your car.
A video posted on Facebook by Sam Bajram on Saturday in Perth, Australia, shows a woman cleaning the inside of her car with a brush meant for the outside of your car. You know, the one that has all the suds and water coming out of it.
We're not entirely sure how this car owner will dry the inside of her car, but we're enjoying the detail that's being put into the clean -- even if it'll leave passengers' bums soaking for ages.
