Commercial Property - Laundrette Business

I am considering creating a laundrette business from an empty shop I have. Of course the hands-off issue is the main attraction, as well as the fact that it’s a clean business (excuse the pun!).

Can anyone with experience in this field give some suggestion / pearls of wisdom.

Thanks in advance,

Regards, Malik

my wife recommends using finish biological...... and remember it is not a clean business at the beginning.
