The most professional looking spotters in my opinion are from Alltec, but the solution is not too good, so I`ve replaced it with my own.http://www.alltec.co.uk/page/1o67z/Eco-Carpet-Care/Eco-Spotter.html
I got mine from world of clean they design the label and sent the bottles with the solution in it. I had to stick the labels on and put the trigger spray on as well they sent a box of bottles and a box of trigger sprays it only takes 1 minute to do one and they look great I payed £1.20 each I think and there is no risk your end.
