I reuse the vinegar. I have used this vinegar for over a year and occasionally refill to 1 L if needed
The lime scale is building up in the tank and inside the machine
In the kettle the lime scale is on the bottom. The steel ball will catch some of the lime scale
Add vinegar to your coffee machine and turn it on
Stop when half of the vinegar have run through. Let it sit for 20 mins or so. This to rinse the inside of the machine. Turn power back on and let all the vinegar run through.
Pour the hot vinegar into your kettle and turn it on.
Run water through your coffee machine a couple of times to get all the vinegar out.
Reuse the vinegar. You can also use vinegar on your shower head and other places where lime scale builds up. Don't use vinegar on marble it will brake down the chalk as it did on the lime scale.
Rinse the kettle with water. If you have a lot of lime scale in your coffee machine, run the vinegar through a couple of times until it is clean. In the kettle leave the vinegar in over night.
