When it comes to laundromat machines, there are a few things to consider in terms of sanitary concerns. First, it's important to note that laundromat machines are generally cleaned on a regular basis - typically once a week. However, it's still possible for them to harbor bacteria and other germs, so it's important to take some precautions when using them.
One of the best things you can do is to bring along your own laundry detergent and fabric softener. This way, you can be sure that your clothes are getting clean without any residual bacteria from the machines. You should also consider bringing along some disinfectant wipes to give the machines a quick once-over before you start using them.
In general, as long as you take some basic precautions, laundromat machines should pose no major sanitary concerns. Just be sure to clean up after yourself and don't leave any dirty laundry lying around!
