Hi guys, I use unger extension poles that easily get me from the ground to a height of about 7m. I have the unger clamp which I use on my pole every now and again. But I'm really struggling to find a way tho properly clean upvc frames and cills with my pole. I've tried microfiber cloths, sponges etc. And it's just not working to the standard I want. Is a upvc cleaner really needed? If so how would u use it in companion with a pole? Any advice or how you get around this factor would be highly appreciated. Also if theres any upvc cleaners suitable for pole work what and how would you use them. Thanks guys ?
