How do you apply it?If using a back pack I don't think the softwash mix is supposed to be good for the pump.I just use virosl but from what others post I guess softwash would give better results.
If the roof is just dirty a 10-1 virosol mix works fine , if it’s green with algi and white plastic is going grey then a 6-1 hypo mix applied through trolly or back pack will kill it off , just rinse fresh water through the backpack after and they will be fine .

Ubik all day long for me.
Don't fancy spraying hypo at gutter level on even a slightly windy day.

I’ll test it on my £10 pump sprayer and just rinse it out thoroughly after . It has handled tfr almost neat sometimes for the last year so ain’t worth spending £70 if this will do the job… if it ruins this I’ll get an ik sprayer ☝️🤣🤷♂️
