Old dear, lived alone for 6 years (bad bowels, only cooked on a grease pan etc), cleaning firm called me to say it was worst she had seen, black top worse than any pub or club I've done and I had to fasten my laces as my shoes stuck to the minger.
It was that deep I found loads of sweets, coins and a FULL big toenail (no sh!t) hidden in the guck
Powerburst and citra boost rinsed with f90 liquid solved it, followed with an application of craftex odour killer (big time)



The smell..............ooooooh the smell!!!!!
the photos do it no justice, it was sooooooooooooooooooooooo bad!!
