You can wash Gore-Tex clothing in a washing machine, but it's important to do it carefully to avoid damaging the fabric. Always follow the instructions and use a gentle wash cycle. On top of that, avoid washing Gore-Tex clothing with abrasive or heavy-duty fabrics, as this can damage the fabric. Gore-Tex clothing can also be tumble dried on low heat. This can help to reactivate the DWR coating on the fabric. Avoid using high heat or ironing.
