Have a couple lareg estate agents i clean the windows get very dirty as on the seafront - windows are slightly too high (literally by about 60-90cm) to do from ground level and several very wide panels - i have tried a work platform (screwfix painters one kinda thing) but it felt still a little to low. So i been using little giant ladder which is good but heavy kit / slow to move around, overall it feels like a slow method and i am sure there is something quicker -what kit would you use for this ? Tripod WC ladder maybe ? Or pole with flip applicator / squeegee ? any other methods appreciated -thanks
