really wish I'd taken a photo of a clean i did in a student let today, guess the reason i didn't was disbelief and or shock, there was a brown stain in one corner of the room, looked a bit like dried up chocolate milk shake, i sprayed it and agitated then started cleaning it, it was only when i lifted the carpet that i found a pile of rabbit droppings! that's a new bullet point for my yellow pages ad eh ?
