Agreed, its a bit like watching 60 minute makeover, on camera and from a distance everything looks nice but anybody
with a bit of decorating experience can see the botch job it actually is.
That said you cant really go wrong with the type of window Nathan's showing on his video especially on short interval repeat cleans, wouldn't it be great if they where all like that.
Just to be clear, I'm not saying Nathans clean isn't ok just saying the quality video doesn't prove it.
