How do you get hard water calcium buildup off the heating coils in dishwasher?

To remove hard water calcium buildup from the heating coils in a dishwasher, you can use a mixture of baking soda and white vinegar. Here are the steps:

1. Prepare the Mixture:

- In a small bowl, mix equal parts baking soda and white vinegar. The mixture will foam and bubble as the two ingredients react.

2. Apply the Mixture:

- Carefully pour the baking soda and vinegar mixture directly onto the heating coils. Be cautious as the mixture can splatter due to the reaction.

- Alternatively, you can soak a cloth or sponge in the mixture and gently wipe the heating coils with it.

3. Let It Sit:

- Leave the baking soda and vinegar mixture on the heating coils for at least 30 minutes. This allows the solution to work its magic and dissolve the calcium buildup.

4. Scrub Gently:

- After 30 minutes, gently scrub the heating coils with a soft brush or a non-abrasive sponge to help loosen the softened calcium deposits.

5. Rinse Thoroughly:

- Rinse the heating coils thoroughly with clean water to remove the baking soda and vinegar mixture.

6. Wipe Dry:

- Use a clean cloth or sponge to wipe the heating coils dry to prevent water spots.

This method is safe for use on dishwasher heating coils and is an effective way to remove hard water calcium buildup. However, if your dishwasher has a heavy buildup of calcium deposits, you may need to repeat the process a few times to achieve desired results.
