    Just cleaned the underside of my pergola which was covered with black algae. Spent 10 minutes doing one strip with a high pressure clean only 46 strips to go. Then I found this 30 second cleaning from Bunnings
    30 Seconds 5L Outdoor Cleaner Concentrate

    This stuff works like magic !! I sprayed it on with a pressure pack and the algae literally disappeared within 30 seconds.

    Highly recommend !! :D

    This photo is of the strip I pressure cleaned, I'll attach another one soon of the 30second cleaner section. IMG_0535.JPG

    Not sure if that's the same exact product I compared to, however if u look on the bottom of the main front label it should show what the active ingredient is, which is likely the same as this product I purchased instead Hy-Clor 1L Super Algaecide used for swimming pools, however its ~40% more concentrated for = $.

    I mix what ratio I need with some dishwashing liquid so it holds/grips to surface, whether in spray or bucket for broom scrubbing (i.e. driveway, pavers etc).

    Can obviously also be used to get rid of algae in showers and roof tiles etc.

    Hi, As a long standing external cleaner, 30 seconds is a watered down version of pool chlorine. Sodium hypochlorite is far more useful to clean with. Cheap as, pool chlorine is generally 13.5% so can be watered down to 1 - 2 % and with a good surfactant does a fantastic job of what is pictured.
