Can ice clean a disposal, and when is cleaning not enough?

Ice and citrus can have a place in routine cleaning if the model's manual allows them. I'd keep grease and fibrous scraps out and follow its cleaning instructions. A slow sink drain needs its own diagnosis, though; I wouldn't keep adding baking soda and vinegar instead of finding the blockage.

A hum without grinding, a leak or a new metallic rattle would be a reason to stop using it and check the model's troubleshooting instructions. Isolate the power before inspection, keep hands and fingers out, and use only the specified tools for a jam or foreign object. If the permitted checks don't resolve it, get service rather than keep running ice through it.

Enzyme cleaners can be useful for organic buildup, especially in a slow drain, but they won’t replace mechanically removing a solid clog. They’re also usually slow-acting, so follow the label directions and don’t mix them with other drain chemicals. For a stubborn blockage, a plunger or drain snake is the safer next step.

A plunger or drain snake may help with a blockage in the sink drain, but that’s different from a jam or fault inside the disposal. I wouldn’t feed a snake into the disposal or use it to investigate one; follow the model’s jam instructions, with power isolated, or get service if those checks don’t resolve it.

Ice won’t sharpen the grinding components. If the manual permits it, it can be part of routine cleaning and may help move loose residue through the grinding area, but it won’t fix a jam or fault. If symptoms such as a hum without grinding, a leak, or a new metallic rattle appear, stop and follow the model’s troubleshooting instructions rather than trying more ice.
