For anyone who hasn't tried it yet and feel ubik and virasol are bit rubbish, here's a quick review..
In terms of dilution rates and cleaning power, no nonsense beats both of the above easily.
You only need 5 cap fulls per 20 litres of water, although i add alot more for extra oomph.
It's a clear liquid so don't have to worry about stains and it's very high foaming, comparable with cif, so you get great coverage.
I cleaned a really really dirty, green, black stained, moss covered, bird poop target of a conservatory roof a couple of days ago. I know ubik/virasol would of achieved maybe just about acceptable results with alot of elbow grease, but would of struggled on the heavier soiling. Normally i get out the cif for these bits.
No nonsense destroyed everything.
I sprayed it on, left for 5 mins, then scrubbed with a low water flow. Everything just melted off effortlessly, even most of the black stains which ubik/virasol really struggle with.
Definitely made the job far easier.
If you like the high foaming action and cleaning power of cif but want the coverage and benefit of using in a backpack sprayer like virasol/ubik, then no nonsense is a no brainer.
