Morning guys,
I used to run a chemical company which made loads of different types of chemicals (carpet cleaner, general purpose, graffitti remover, etc) and I always tested dilutions on various surfaces to find the most effective and best rinsing dilutions.
But, the simplest piece of advise was always to think of Fairy Liquid when you are mixing chemicals. Would you mix Fairy Liquid at 5-1 when you are cleaning dishes? Not a chance! if there are soap suds would you rinse with fresh water? Of course.
I never understand putting chemical on to a surface and not rinsing! Why take the risk with carpets?
Cheers
Dave
