Just thought I would alert you all to this stuff... http://www.diy.com/departments/hg-window-cleaner-bottle/161656_BQ.prd Its only my second day using it and I love it. Its got me wondering what all the other specialist window soaps are like now. Its best feature is that it is so easy to detail. Its like wiping off plain water, instead of a sticky soap, yet it has loads of slip. Bubbles up nicely, and leaves a good shine. I've bought about six bottles now, and I'm saving my magnum premium for the dirty 1st cleans where the waters just going to get chucked anyway. With my trade card I'm buying it in for £3 a bottle at B&Q. On the subject of B&Q has anyone seen that they now have a huge industrial cleaning section?
