If a mat is not in good repair, germs found on the mat's surface have the opportunity to migrate through the rips in the mat to the foam padding beneath potentially perpetuating problems for your team.
Many programs share their mats with other sports or school programs.
Just because the disinfectant says it's for wrestling mats does not mean it kills all the germs that plague the sport. To see what viruses, bacteria and fungi the disinfectant kills, read the label on the bottle or the box. If the organism is not listed on the label, then the disinfectant may not kill that germ. This is an important step in your team's hygiene protocol. If the label does not list the germs that you want killed, then it may not kill them.
