We use a public laundromat also usually early morning when no one else is likely to be there. I wear a mask and gloves and spray disinfectant/ wipes and hit all the handles controls and folding tables. Then load the machines and wait outside to load dryers after spraying/wiping them down. If anyone comes in we fold at home after washing our hands I usually wipe down any surfaces on the car we may have touched. Probably unnecessary but it makes me feel better knowing rather than hoping.
