Cleaning a polycarbonate sloping roof
We have a polycarbonate sloping roof over out deck and side passage.
Over time it gets lichen (I think) growing on it, possibly algae too. Looking for ways to clean it (beyond just a brush and hose pipe) and found https://www.wetandforget.co.uk/resid...ervatory-roof- cleaning Reading the justifications in the sales blurb made me think they were struggling for reasons to use it, however the "spray on and leave it" seems attractive. The side passage roof can only be accessed from our neighbour's property. Just wondering if anyone has a proven method of cleaning plastic roofs with minimum effort and long term effectiveness.

Others will be along in a moment with other solutions but wet and forget is probably just a watered down BAC50 https://job-prices.co.uk/best-moss-killer/ I've use BAC50 on a polycarbonate clear roof and its worked well. The results are not instant. You will see the die off after a few days but it will take a few heavy rain showers over a period of a month or three for the dead material to wash off. -- mailto : news {at} admac {dot} myzen {dot} co {dot} uk |

CAS# 68424-85-1 i.e. Benzalkonium chloride Thanks, team! :-) Cheers Dave R -- AMD FX-6300 in GA-990X-Gaming SLI-CF running Windows 7 Pro x64 -- This email has been checked for viruses by Avast antivirus software. https://www.avast.com/antivirus |

Only one issue: "do not allow the chemical to enter drains or waterways" so I'm not sure how you are supposed to treat any roof unless it is absolutely certain that it only drains into a soak away. Our roof drains into the main sewerage system.

That was written by the same people who wrote my computer printer manual? "When cleaning this printer, do not immerse it in water." |

So when looking for MSDS on the web, make sure you don't inadvertently pick up the wrong one. I've known UK wholesale suppliers provide the wrong MSDS on their web sites. |

Exactly - and how do the professionals who use the same chemicals stop it entering the drains. They probably don't! You will be diluting the BAC50 10:1 to 20:1 and then just wetting the roof and letting it dry. There will be little run-off to the drains at this point. Anything thereafter will be diluted much further by any rain. The amount that enters the drainage system for a one or two off application is probably no worse that than what gets put down the toilet or sink plug on a daily basis. -- mailto : news {at} admac {dot} myzen {dot} co {dot} uk |
