Actress Monica Potter has taken inspiration from one of her favourite pastimes and is working on a line of cleaning products.

The Parenthood star has turned her personal obsession with housework into an aspiring business and insists she finds her new sideline project almost as enjoyable as her acting career.

She tells Us Weekly magazine, "I'm working in my little lab and doing inventions and things. I make cleaning products. I have a home line that I'm working on. I just love cleaning and keeping the house.

"I sent in the patents today for a lice spray. I know, I'm weird... It's really fun. It's a lot of work. I'm not sleeping a lot, but it's the most gratifying thing next to (acting)."
