I have been using Koh since they first launched . Have always loved the surface spray, especially for glass and chrome. I have taken up all the new products (laundry, dish and dishwasher ) and can honestly say I was wondering if they would be as effective as the commercial brands . Honestly they did not disappoint and I have converted all my family ( they laugh at my continual “use Koh” for every stain disaster !) . I use it for anything and everything. love the way you put it on a stain , rub and go back the next day and it has faded into oblivion ! I have a new car and even use the dishwashing liquid as car wash ! From a Koh fan from way back .
