Is it normal that i bring my own disinfecting wipes to the gym?

It doesn't matter what gym I go to to work out at, the equipment is always filthy. I don't trust the sprays the gym provides to clean the machines, so I bring my own disposable disinfecting wipes from home. Every time I wipe down the machine, the cloth turns grey with other people's filth. It even happens after someone else just "wiped" it down. I like going to the gym since it has a better atmosphere or vibe than working out alone at home, but gosh it's disgusting. The dirtiest pieces are the handles of the cardio machines.
