But not by cleaning it. I put the pole up against the frame, brush facing up. I saw a tangle in the hose, untangled it, and pole fell down, aluminium gooseneck just caught the window pane, left a small scratch. Really silly.
Was honest to the customer, customer was fine about it, said she wouldn't loose sleep over it.
This is one of my best customers, and promised her I would fix it.
Now, I've heard of the toothpaste job, but not too sure about that. It's not a deep scratch, my nail doesn't catch on it.
Can I use a car screen repair kit for it? Or are there specialised kits on the market? Quick google didn't come up with much.
