Quick answer
Clean the drip tray and bottle grate after every few uses, and replace them when you notice cracks, warping, or stubborn residue that cleaning won't remove.
Why regular cleaning matters
The drip tray catches spills and drips from the bottle, so it can quickly become a breeding ground for bacteria if left damp. The bottle grate sits under the bottle and can collect dried formula residue, which is hard to remove once it hardens.
Cleaning both parts regularly not only keeps your countertop tidy but also prevents buildup that could affect the fit of the bottle or the tray.
Signs you need a replacement
Even with careful cleaning, these parts wear out. Look for cracks, warping, or discoloration that doesn't come off with washing. A warped drip tray may not sit flush, letting spills escape onto your counter.
If the bottle grate has broken prongs or a rough surface, it can scratch bottles or make them unstable. Replacing these parts is inexpensive and keeps your machine working as intended.
