Perth woman washing inside of car becomes viral star

A Perth woman has become an accidental viral sensation after being filmed vigorously washing the inside of her car at a car wash.

Sam Bajram told WA Today he was waiting to use the Malaga car wash last Friday afternoon when he saw the woman soaping up her car's interior.

Video shows her scrub down the doors with the brush before moving on to the floor, spilling suds all over the inside.

"At first I thought she was a bit nuts," Mr Bajram said.

"Then my partner and I had a little chuckle as she started scrubbing the doors."

The video has been viewed more than three million times since being uploaded on Friday, with some contacting Mr Bajram to share their thoughts on what the woman was up to.

"Someone said maybe she had killed someone and was wanting to wipe away the evidence," he said.
