I have asked for the same more than once. In the meantime, here is the text from the email I received today from Andy Taylor. Hopefully he won't mind me reproducing it on here:
Thanks for your email, you are correct I’m aware of the cleanliness issues.
This is something that we have tried to address over the last few months however it has proven rather difficult to resolve. As you know the stadium are responsible for the cleaning contracts and the standards as such are managed by the stadium manager. We have questioned whether the stadium would be ready in time for the first home game and were assured many a time that everything would be ready.
We were pushing for enhanced cleaning throughout the final week leading up to the Charlton game however nothing really started happening until we bombarded the stadium manager with lists of concerns and lots of pictures too!!
There were cleaning teams right up until late on Friday night including the stadium manager who was personally cleaning toilets
However as much as there was a flurry of activity, I believe they left it too late and then rushed through thus resulting in a sub-standard clean.
Please allow me to apologise on behalf of both the club and the stadium company. There is no excuse for the poor cleanliness many fans have had to experience.
There has been a massive push over the last two days to raise the level of hygiene. I have personally seen cleaning teams wiping down seats, jet washing steps and walkways and cleaning toilets thoroughly. I have personally been into every toilet and ensured that paper towels and toilet paper is in place.
Hopefully tonight experience will be a lot more enjoyable.
The biggest concern we have currently is the pigeon guano. We are currently seeking a pest controller to help us remove the risk.
Please rest assured that we are working with the stadium company to resolve this ASAP.
