Sorry for excessively dull Friday night subject matter!
We have been spring cleaning and I found a small box of non-bio washing powder at the back of the cupboard under the sink. I can remember when I bought this - we were on holiday in France in 2014. So it's 5 years old. The box has got slightly damp and the powder in it is a bit solid, but I could break it up and use it.
Would you? Do you think it will still work? Am I completely over-thinking this?
