My T has recently left (at last!). The back bedroom stank of just about everything a room could stink off! Cannabis, wee-wee, lager, BO etc. I washed the ceiling and the windows with Cilit bang to get the smoke off. Stripped the wallpaper and then tackled the relatively new carpet.
It was brown stripes so didn't really show the colour of the stains. I cut it up and put it in binbags (double rubber gloves job!).
Then I examined the stained (and still wet) floorboards. And Yes, I sniffed the stains to see what it was and to decide what to clean it with. I scrubbed and cleaned it.
NOW - the tenantproof bit is..... To prevent further spillage of stuff onto the boards I am thinking of using underlay. It's a very cheap kind of underlay the name of which I have forgotten but it's black and like the stuff you put under laminate flooring. Plastic foam stuff. It needs to be sprayglued down, but I'm hoping to be able to wipe it clean after the next dirty b****rs mess it up.
Anyone tried this?
