We clean a chinese resturant twice a year and I have used traffic lane cleaner, and then Ultrapac renovate in the past. BTW the carpet must be many years old!
I have just had a look at it, and I am thinking I need to use something different that with the advice from here can hopefully be a better pre cleaner than I have used before.
So my question is - What would you use on a VERY greasy, well trodden in Chinese resturant carpet?
Thanks for any pointers.
