Sounds like galvanic corrosion. If you're somewhere that salts their winter roads, this is why people ride beater bikes.

A fix might be to smear the valve stem and around the valve hole with a thin layer of RTV siliconesilicon or possibly a grease to stop the two surfaces coming in direct contact.

BrassCombining brass and aluminium areis generally considered incompatible

You might prefer to choose tubes that have rubber up the sides of the valve stem (not uncommon on Schrader but rarerrare on presta) or some tubes use stainless steel valve stems.

To be honest, I'm surprised there aren't more corrosion problems between alloy rims and brass valves.
