Hi Alex
Many many babies have been fed with equipment that has been through the dishwasher and survived!
It is probably latest 'best practice' advice that health visitors are meant to give out, and perhaps in some areas or some washing products do leave more salty residue, but dishwashers rinse and in the past, some mums have used this super-hot way of cleaning bottles instead of even sterilising.
I found that when I washed the bottles in our dishwasher, they never really got completely clean – the 8floz bottles were too tall for the water to really get all around the inside of the bottle thoroughly, but if you find yours are gleaming, then I think you'll be fine.
Do you sterilise your bottles afterwards? If so I am sure you are fine. If not, you might want to start rinsing them quickly with new water after they've been cleaning in the machine, then sterilising them.
Even people who hand wash their bottles sometimes miss a spot, so you are in no way a criminal for what you have been doing!
