"Many cleaning products are like using a sledgehammer to crack a nut," claims Aggie MacKenzie, star of Channel 4 TV series How Clean Is Your House?

A better option than antibacterial cleaners and wipes, she believes, is the probiotic approach offered by a new range of cleaning products that bears her name.

The story of Aggie's Probiotics began with Aggie mentioning Wheelers Beeswax polishes in one of her magazine columns. Sales surged 70% prompting Wheelers brand owner Footprint International to seek out Aggie and persuade her to work with them on product development.

The result, launched last October, was an initial line-up of three products: 500ml multisurface cleaner, 500ml bathroom cleaner and 750ml toilet cleaner (all rsp: £2.99). Available from Sainsbury's, Booths and Lakeland, they will be joined this year by a 500ml washing-up liquid (rsp: £1.49).

Aggie says the difference between her probiotic range and ordinary chemical and antibacterial cleaners is that it acknowledges that only 1% of bacteria are harmful, while the other 99% help to keep us healthy.

"The problem with ordinary cleaners is that they kill up to 99.9% of bacteria on a surface, including the friendly bacteria that help provide us with a natural germ defence," she says, adding that Aggie's Probiotics work differently.

A combination of natural cleaning agents and 'friendly' bacteria is used to clean and then protect a surface, preventing the growth of harmful bacteria for up to eight days, according to independent studies.

Since the launch five months ago, the range has performed particularly well through Lakeland, says Aggie. Footprint International believes all major retailers will carry a probiotic cleaner by the end of 2011.
