Yes, it is generally a good practice to wash clothes before donating them to Goodwill or any other charitable organization. Donating clean and freshly laundered clothes shows respect for the recipients and the organization's volunteers or staff who handle the donations.
Clean clothes are also more likely to be accepted and put out for sale, ensuring that they can be beneficial to those who purchase them from the thrift store. Additionally, it helps maintain the overall hygiene and presentation of the store.
If you have clothes that are in good condition but need washing or minor repairs, it's worth taking the time to clean and mend them before donating. This small effort can make a big difference in the impact of your donation and the experience of the recipients.
