I have used the same chemical brand for many years and to be honest I have tried some others and I dont think anything else comes close.
What chemicals have you used for certain jobs and found that they cant be beaten ?
Ok, on the QT here...depending on the.... "certain jobs" then I have heard Just for men is great for colour or Immac for removal.
Seriously, as Wynne says powerburst, and pureclean, cant rate it enough.
