Doesn't matter how it happened, but someone has been round our house and wiped all of the glass interior doors and the bifolds and the back door with a cloth which had been used with lots of furniture polish on it. Oh and the tv and my computer monitor.
I've now been trying for three weeks, and every window is still smeary. I have attempted to cleaned with glass cleaner; with hot water and washing up liquid, with kitchen spray, with vinegar and with vodka. Everything is still smeary.
I spent two hours on them this morning and it's not any better.
Please for the love of god what do I do.
