are you for real?what absolute rubbish!DI purified water is no different to RO purified water......if your getting phone calls because he s not doing a good job its because he s a **** window cleaner!?
He isn’t doing a bad job , they are clean ish but ro does a much better job , you probebly think your golf gtd is fast and to you it is put it up against a Ferrari and it’s a snail , it’s exactly the same with Di and ro ,ro will always give a better finish .
again petrol is a good example of this 95 octain the car will run ok but use 97 or fuel addertives like methanol etc it will run much faster
