I wear a face sheild and coveralls, is this suitable?** A: You are pushing my maths a bit. One in seven is about 14%, so that would equate to 7% BAC. That seems a bit excessive for normal (antifungal) use. I use about 2% strength (50ml per litre). **Q: Could I dilute with water to spray indoor air and carpets?** A: I’m not sure that would be a good idea and why on earth would you want to spray a moss killer on your carpets ??? ## Customer Reviews ### ⭐⭐⭐⭐⭐ Block path. *by A***R on 30 March 2026* Arrived on time bac 50 cleans our block paving very well moss and weeds.
