La Rochere glass is durable, dishwasher and microwave safe (short period), however we recommend the following care instructions to prolong the clarity of your glassware.
Glass is sensitive to water hardness and may react depending on the water you use. Hard water: a whitish sediment may build up on the glass. This can easily be removed using warm water mixed with white vinegar or lemon juice. Freshwater or acid water (pH < 6): Freshwater may etch the surface of the glass, turning it slightly bluish and opaque over time. To prevent this from occurring, we recommend hand washing glasses so they do not soak too long in water.
Please avoid severe thermal (extreme heat or cold) shocks.
