Origins of Soft Washing

Soft washing originated in North America around 1985 in Tampa Florida.  The reason for soft washing was to develop a gentle way of cleaning roofs without the damage typically caused by pressure washing.  Over the years the soft wash cleaning method has developed and is now the only roof cleaning method approved by the North American Asphalt Roofing Manufactures Association® (ARMA).   

How Biocide Soft Washing Works

ecosoftwash® uses a custom cleaning solution with a unique combination of biodegradable selective fungicides to target moss, mould, algae, lichen and general biological growth.  Once applied it immediately attacks those selected growths, killing even the deepest rooted spores.  These fungicides work in conjunction with a range of surfactants to help loosen and lift the biological growth.  Over the following twelve (12) months and beyond when it rains, this safe, sterilising cleansing combination reactivates to help flush the decomposing biological growth away, without scouring the surface they have infested. 

Why Soft Washing?

Soft washing was developed out of necessity for a roof clean which would kill all mould growth including lichen for the long term WITHOUT damaging the surface . Unlike high pressure washing which has an effect similar to “sand blasting” causing surface pitting which only encourages greater mould regrowth.  Every time any surface is pressure washed it will only remove the moulds biological growth making the surface appear clean, guaranting never killing the mould spores, the heart of any mould.  As a result, within one to three years the mould infestation levels will double making the surface appear darker.

ecosoftwash® is Melbourne’s only specialist that uses this exclusive biocide cleaning method that produces a premium long term clean every time.  We achieves this by using the latest water saving, no pressure, premium soft washing technology to gently apply our eco-friendly, biodegradable (pH7) same as tap water commercial grade custom formulated mould killer to any roof or exterior surface.

No. Our eco-friendly and biodegradable chemical contains no bleach or chlorine eliminating the need for rinsing. Products containing bleach or chlorine should never be used.

No, soft washing will remove all the moss & mould making your roof look like new eliminating the need for painting.

Generally (subject to mould infestation and rainfall levels) it takes 12 months or so for the rain and wind to remove the dead biological growth from the roof to produce a clean exterior surface.
