I have today tried Lidl own brand, W5, window and glass cleaner.
Excellent results, no smears, nice smell and less than £1.50 (could actually be less than £1, can't remember) for a litre.
Might take me the best part of a long time to use it up!

, so have not found out if the Lidl cleaner works as well with the Karcher.
