Campus custodians are scrubbing towards a greener clean.

The custodial staff at Dalhousie University recently traded in 40 chemical cleaners they use everyday for three green cleaners. One of them is a multipurpose cleaner with bacteria that loves organic waste.

“Basically the bacteria go to work and eat this stuff, and it’s gotten rid of terrible smells we’ve had in washrooms,” said Mike Murphy, manager of environmental services.

They put out a tender last summer and hired Avmor Ltd. from Montreal.

“It’s less expensive, as a matter of fact,” he said. “That wasn’t always the case with green products, but more and more people are demanding them and the prices come down.”

Murphy added they’re saving between 20 and 25 per cent.

Mount Saint Vincent University has been using green-certified cleaning products for five years, said Robyn McIsaac. She said green cleaners are safer for the custodians and better for staff and students who have scent sensibilities.

“The one exception where we’re still looking to find a product to meet our needs is our wax sealers for the floors,” she said.

It’s a problem common to most of the campuses — the one green product that doesn’t pass the test.

Saint Mary’s University started the process five years ago and fully converted — including hand soaps — last year, said Gabrielle Morrison.

The green cleaner program is just getting off the ground at the Nova Scotia Community College. The new waterfront campus has gone green, but the other campuses are just heading down that road, said Jim Farrell, manger of energy and sustainability of NSCC.

“All the campuses are presently using or experimenting with some green products,” he said.
