Oily Restaurant Carpet?

[PaulAmbassadorMan]

Using Encap-Punch would actually be a better choice for a pre-spray than DS2 on a restaurant carpet. But when I read your question, I was thinking you were limited to DS2 since that's what you mentioned (my mistake). If you're open to using both products - Encap-Punch is the way to go. Using Punch and DS2 together will produce excellent results!

I have some samples of the Encap-Punch. 
I only clean this location every other month. 
But it never seems too dirty.
