Dont they use bucket and water anymore?
I live in a flat on a main road and Ive just paid £20 in London for three sash windows. It took him 10 minutes. And i dont know what he cleaned with I only saw a cloth. They look much better but not brilliant theres smudges there that I cant reach. I asked him to do the pvc door and he literally wiped the bit of glass in it. I was expecting a bucket of hot water chucked over the full thing😃
