More then 30 people turned out to Pioneer Cemetery yesterday to see how to clean a headstone using a waterblaster.
A cemetery preservation group asked Roger Hoar, owner of Headstones Wairarapa, to put on the demonstration to show people how simple it was to tidy up a loved one's gravestone.
"It's very simple to do and brings it back looking like brand new," said Mr Hoar, whose business had won three national awards for its restoration work.
"We are quite passionate about trying to restore the history of our town."
He said granite was one of the hardest minerals "next to a diamond" so waterblasting granite headstones was an effective and cheap way of cleaning, which people could do themselves.
