Avoid putting your goalkeeper gloves in the washing machine. The combination of the washing detergents, the spinning motion and temperature is very likely to reduce the durability and performance of your gloves.
If you love your gloves, treat them like a you would a new car by using a simple 3 step routine: Firstly give them a quick rinse to remove the excess dirt. The second step is good wash using a decent glove wash and finally rinse and dry well
Use a glove wash in a spray bottle, this has a key benefit. You use less as the spray allows you to apply it directly to the areas where it is needed most.
The sooner you can wash your gloves after a match the better. It means that the dirt doesn't have time to dry into the latex and also reduces the chance of bacteria developing.
When drying your gloves all you really need is a towel and some pressure. Wrap the gloves in the towel and use either your hands (or even your feet) combined with your body weight to apply pressure to the gloves. Once the majority of the moisture has been removed, just air in normal room temperature until nearly dry. Avoid putting your gloves on a radiator or in a airing cupboard at all costs, this will damage the latex on your gloves.
