Cleaned a big farmhouse yesterday and was embarrassed to take the money.
Old grey render over leaded windows!! There were limescale and lead deposits everywhere and they hadn't been cleaned in 7 years.
I ended up removing some of the limescale from the windows with a scraper it was that bad. Scrubbed and scrubbed with a Harpic limescale remover on scrims but it wouldn't touch the stuff.
I left the job feeling completely dejected and like a bloody crook. However it's a 4 monthly job and I have promised to return in the interim free of charge with some heavier duty cleaning equipment.
Would TFR remove these kinds of deposits on the glass or are the window knackered. I've never used the stuff so need some advice on this one please.
Regards,
Lance
