Zac Efron has cleaned out his closet to raise money for charity.

The High School Musical star has emptied out his cupboards and found more than 300 items to donate to the Children's Resource Network of the Central Coast charity.

The 24 year old handed over a big bundle of clothes last month (Nov11) to raise funds for the organisation, which gives clothing and school supplies to children in need.

Charity boss Lisa Rey admits she didn't recognise the actor at first, but was completely starstruck after he introduced himself.

She tells Sanluisobispo.com, "He looks at me and says, 'Hey, I'm Zac Efron,'...And I screamed. I'm screaming like I'm a 13-year-old girl... His gift says a lot. It's not only the clothing. It's having something special that other kids wouldn't have access to. It shows them that people do care."
