We have a large guttering to clean which is covered in green and black gunge and needs a bloody good clean. We are going to spray with TFR, but which would you advise which we can dilute/ratio with water to then pump from a just a normal weedkiller pump action sprayer. This is a one off at the moment, so a small container of it would be best for us.
Also best place to buy?
I know there are loads of threads on this, but I've never bought one that is concentrated..............only the normal ones you buy from auto shops for cleaning off bugs...lol
thanks
