Well the floor was disgusting. Not greasy just nasty. I used Viper Venom and it cleaned up great. There were no coatings on the floor. We agreed that I would come back and reclean later this year and coat it for easier maintenance. Pretty simple job. The customers complaint or the reason for having me clean it was their socks were being ruined from walking around on the floor. Sure enough I saw her put on clean socks and walk around a bit, but the floor was clean. I am also sure a neutral cleaner would have worked just as well.
