Hi Helen.
The fact that its a reddish colour in a different container style to the others was a big enough clue. He's also mixed it from the same container in the past for the spray bottle so didn't think it necessary. I think his head was more into who was playing on the wing as he picked the team for his match that night. He first thought that I had put fairy liquid in a container of pure for a joke!!
Some days he's brilliant and others not.
You can mend broke but you can't fix stupid.
I will however change the container for something different and label it now. It's too expensive to waste like that. Although at only £1 a litre I had thought about converting the van to run on it
