Been looking for an alternative to ubik/virosol, as good they are I just don't feel they get rid of stains as easy as I would like.
Got hold of some of this merlin power cleaner on Friday and so far I think it has the edge on both ubik/virosol.
Seems to eat through dirt very easily, my window frames are shining.
Even cleaned the alloy wheels on my car with it, made mince meat of the grime!
Obviously the real test will be green fascias or con roofs but from what iv seen so far this stuff should eat through the green.
It's roughly the same price as ubik/virosol and has a dilution rate of 1.10 on heavy grime so should last a good while too.
