Is it safe to run CLR through your Keurig coffee maker?
Use vinegar... Much safer
I would not dare do that for fear of ruining the machine.CLR is strong stuff! If you need to clean the Keurig, I suggest you run a mixture of 90% water, 10% vinegar; then run water through it 2 or 3 more times.
It is safe to use CLR, provided you follow the safety precautions of using and handling the solution. The solution is good when cleaning the coffee maker, and it gives excellent results.
