Does washing powder kill moss on tarmac?
In this regard, does washing up powder kill moss?
Although not generally viewed as a chemical, powdered laundry detergent has been used successfully in some situations to kill moss. By mixing a cup of powdered detergent with 10 gallons of water you can apply this solution to areas such as patio and kill some of the moss growing on them.
In this manner, how do you get moss off tarmac?
Option 1 - Clean the tarmac, rinse then follow with moss and algae killer and prevention. After brushing your tarmac surface, spray the area with BATIFACE. This cleaner should be left on the surface for between 15-30 minutes before being rinsed with either a hosepipe and brushed or, ideally, a SMALL pressure washer.
Pressure washing can be an expensive removal solution and has the potential to scar your tarmac as it is prone to marking. A wire brush on your surface could also potentially mark your tarmac, and it is also a time-consuming method.
