Use a kitchen scale to measure your solution in fluid ounces.

Take your cleaning solution and pour about two ounces of solution into a container.

Make sure to balance your scale to 0 ounces before measuring by pressing the "tare" button while the container is on the scale.

If you’re using a different descaling solution than the Tupkee brand that is pictured, read the instructions for your solution to see the ratio of water to solution that is recommended.
