Dishwasher

I do! Only just recently, I think they’re fine, they sound a bit creaky putting them together but no leaks or anything! Had to swap my lemon tabs to normal ones though as the smell on them was overpowering

No I just rinse with washing up liquid then clean them out then sterilise in the microwave x

I occasionally put them in the dishwasher but still put them in the microwave to sterilise after the dishwasher
