Hi,
The results look great.
What type of carpet was it and why did you choose to sanitise it?
Just seems like a wierd thing to try, without good reason. We have used this combo on carpets in care homes where they are worried about bugs etc, but we used microsan instead of cleansan (as it kills a raft more things apparently).
Normally, you can sell on the same angle to res clients using a non-cationic formulation that doesnt limit your choice of detergents. Ie you could use an anti-bac deodoriser with double clean/[insert random detergent]/splitter and achieve the same result.
