Bio-Shield 5L Outdoor Cleaner - productreview.com.au Award Winner

Independent lab testing of Bio-Shield®

In October 2014 Bio-Shield was tested and certified by two independent laboratories, Labtec and Hill Laboratories, to have the same active ingredient as Wet and Forget. In November 2014 we invited Wet and Forget to substantiate their claim that Wet and Forget had better performance than Bio-Shield. Wet and Forget has not provided any evidence to substantiate their claim.

How to choose based on price.

The true cost of outdoor cleaners is not how much you will pay to purchase, but the price per litre of diluted solution - purchase price divided by the amount of diluted solution made up. The lower the diluted litre cost the better the value.

A 5L of Bio-Shield has a higher concentration of active ingredient and the lowest diluted litre cost of the outdoor cleaners in the comparison table above.
It costs $126 and makes up 105L of full strength solution - $126 divided by 105L gives a diluted litre cost of just $1.20 diluted litre.

That's a saving from 17% and up to 600% less cost per diluted litre than other brands compared in the Price Comparison Table.

Bio-Shield® is Proven Effective

We have used Bio-Shield® for over 40 years in a demanding commercial environment on a wide range of surfaces, from cleaning concrete to Colourbond, roofs to driveways. Bio-Shield works, we have build our reputation on it.

Bio-Shield will give a powerful, rapid kill of moss, fungal, algal and lichen growths, and can prevent re-growths. It can be used to clean any exterior surface.

For the correct application of these exterior cleaners, it is important the surface being treated is saturated and kept wet until the moss, mould and lichens are dead - in as little as 15 to 20 minutes using Bio-Shield®.

Porous surfaces such as concrete or timber will soak up the applied solution; so the 105 litres of diluted solution made with a 5 litre bottle of Bio-Shield® Concentrate provides more than sufficient coverage for a successful result in most domestic situations.

When Bio-Shield® is used on non porous or smooth surfaces such as painted weather boards or a Colourbond roof, coverage will be greatly increased, making Bio-Shield® even more cost effective.
