Baby bottle cleaning advice


Hello ladies!!!

First time soon to be momma here. So far I've gotten some medela breast pump bottles and spare parts and 2 new bottles that I am wanting to go ahead and clean and store away until its time (im 27 weeks and nesting hardcore haha) but I was wondering could I just simply wash them in the dishwasher (with only the bottles stuff alone and no other dirty dishes) or do i really need to hand wash them and boil them in hot water and maybe even wait for a bottle steamer? Idk how full on propper cleaning I need to do to the bottles. Lemme know!! Thanks!!:)) #duehalloween
