Just water and the odd flat bit of Coca-Cola, but I have a question a lot say bio washing powder I always thought it was the non bio you are supposed to use or have I got that wrong.
I thought that the bio was just as harmful to a cesspit as the nasty blue stuff that we all used to use I blame Facebook and brexit for my confusion.I think it's 'Bio' flavour, Annie.
The theory is that the enzymes incorporated in the 'Bio' stuff attack the organic matter and help break it down. I suspect it doesn't do that very efficiently once the urine gets converted to ammonia but the fragrance added to any washing product helps mask the odours.
BTW I'm assuming that the flat cola is added to your loo having been mixed with vodka and ingested?
