Do I need to toivel a hand blender – it may ruin electrics AND warranty
Also sandwich toaster??
Both of them should be toiveled by placing the whole appliance into the water. Afterwards shake out any water that is inside it, and let it stand in the sun or a warm place for two days, or you can blow dry it, and you will see that nothing will get ruined.
