When you wash your pots, crockery and utensils, you should try to leave them to drain until they are dry if possible.  This is because tea towels can be a source of cross-contamination so don’t use them all the time. After you have used a tea towel make sure it dries out before you re-use it.  Also change them regularly and wash in a hot cycle. If you can, use disposable cloths or paper towels.
