For best results, your waterproof or water-repellent clothing must indeed be clean.Washing is, therefore, a good idea. 😉 Putting it in the washing machine can be option, but it all depends on the tear to your clothing. Do not take the risk of widening it when in the washing machine. It all depends on how dirty the item of clothing is. The fabric might only need a quick wipe with a sponge to clean it. 🧽
When it comes to restoring waterproof properties, we recommend doing it once your repair is complete. This is when you can then consider machine washing it, which depending on the wash cycle, will restore your product's water-repellent properties.
You can also apply a re-waterproofing liquid. 💦
