Compare Wet and Forget with Bio-Shield®

Testing of Wet and Forget by a leading consumer organisation found there was;

'No noticeable difference in cleaning performance between the cleaners tested so consumers can safely choose based on cost per dilute litre'

Why pay $3.60 /diluted Litre for Wet and Forget when Bio-Shield® has the same active ingredient and is only $1.13 / diluted Litre.
Blind testing and review of Wet and Forget was carried out by a leading consumer organisation.  This testing found there was no difference in cleaning performance between Wet and Forget and other outdoor cleaners with the same active ingredient.

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 below.
It costs $116 inc delivery and makes up 105L of full strength solution -  $116 divided by 105L gives a diluted litre cost of just $1.10 cents diluted litre, (including delivery)

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 to work on any exterior surface for Moss, Mould and Lichen Removal.
I have personally used Bio-Shield® for over 35 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 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, mould and lichen, taking as little as 3 months to clean dirty
