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 $99 and makes up 105L of full strength solution - $99 divided by 105L gives a diluted litre cost of just 94 cents diluted litre.
That's a saving from 22% and up to 71% 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 Coloursteel, 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 Coloursteel roof, coverage will be greatly increased, making Bio-Shield® even more cost effective.
Benefits of using Bio-Shield®
- Safe to use and easy to apply.
- Works quickly to kill and remove moss, algae and lichen, taking as little as 3 months to clean dirty concrete.
- Long-lasting protection.
- Cost effective - lower cost per diluted litre than comparable cleaners with the same active ingredient.
- Unconditionally Guaranteed To Work
