Grangers FAQs
Q: What’s the difference between the XT spray-on and Extreme Wash-in Re-proofer?
A: It’s basically the same product, but the best method of application depends on the garment. In most cases, the wash-in product give a more even coverage. But if you’re reproofing a garment with a drop lining, such as mesh for example, it’s better to use the spray-on because you only need to reproof the outer material.
If you have the option to use either, Granger’s say the wash-in product is better. That way, you treat the whole garment, and it’s less likely you’ll miss a bit.
Q: Which is better: hand wash or machine wash?
A: Machine wash is almost always better. Granger’s products are designed to be used in domestic washing machines. The only garment that really won’t thank you for a machine wash is anything with down filling and some soft shell garments.
Q: How long does it take to activate the DWR treatment in a tumble drier?
A: Around 50-60 minutes at 50-60 degrees C. Don’t forget it takes about 15 minutes for the drier to get up to temperature.
Q: I don’t have a tumble drier; can I activate the DWR finish with a hairdrier?
A: No, the heat is too concentrated. Radiators are out for the same reason. You can use an iron on low to medium heat, but because outdoor clothing tends to have lots of panels, this can be tricky. If you are using an iron, don’t put a towel between the hot-plate and the garment. It won’t activate the finish properly.
Granger’s don’t even recommend using the driers at a laundrette because these can run twice as hot as a domestic drier, which could be disastrous.
