Depends how you mean keep them from getting damaged. Do you mean while people are renting or in general.

I recommend
Proper washing and drying
Sort your laundry
Use garment bags
Zip-up zippers and fasten buttons
Turn clothes inside out where you can to avoid damage on the right side.
Avoid overloading the washing machine with these garments.
Be cautious with stain treatments
Store clothes properly
Avoid direct sunlight and heat
Regularly inspect and mend
Use gentle washing cycles

Feel free to message me if you are meaning more specific 🙂
