Towels don't need to be ironed so they are easily cleaned and quickly ready for using. There's a difference between kitchen towels and frothy towels.
In order to keep frothy towels clean and fluffy it's is important to wash them in soft water with fabric softener and dry them in a big drying machine. More drying space means softer and lighter towels.
It's more difficult with kitchen towels. Special chemicals are needed to keep them clean. Kitchen towels are usually dirty and smell bad. A good way to treat kitchen towels is with vinegar and baking soda. In order to remove bad smell wash kitchen towels with vinegar in a washing machine with no other washing chemicals on high temperature. Another way is to add washing chemicals and vinegar into the washing machine and start washing. As soon as chemicals are poured into the washing machine, pause the machine for an hour and let your laundry soak. After the hour resume washing. That's it.
