I have a house that has a big rose bush in front of the window. Once a year they cut it down & I can clean the window. Got there today & it's been cut down. So I spray it with viakal & let it soak in while I do upstairs Windows. Come down & without thinking soak the bottoms with my applicator then realising it a now be covered in viakal. Anyway window came up fine so thought shall I rinse applicator out or carry on. Carried on & what a difference with a bit of viakal on it. Squeegee felt like it was on ice. Glided lovely & was brilliant with the liquidator. Have I discovered a new mix. Gonna try it again tomorrow to see what happens.
