Mrs Mickly!!
I have a microfibre cloth that I use exclusively for cleaning my helmet ( Settle down there at the back !! ), got home today and wiped it down only to see it covered in a white residue ( for gods sake stop it you lot !! ), I sniffed it ( right! that’s detention for all of you ) and diagnosed that Mrs Mickly had used it to clean the inside of the windows at it smelled unmistakably of windowlene!!
When confronted with the evidence she cracked, admitted her sins and gave me her hankie to polish it off.
Foot note: I was of course in the wrong as I shouldn’t have kept it in the kitchen where I clean my helmet, but in my sock drawer
