If you use tap water for tea, limescale deposits will build up over time on the surface of your electric kettle or tea maker. 

How to Use
To remove these and keep your appliances running smoothly, scale must be removed using these descaling tablets. 

Simply dissolve a tablet in about 8 ounces of water, and run the appliance using its 'black' tea setting. For optimal performance, we recommend descaling your kettle or tea maker once a month.

For VelociTEA that will not Circulate
If your velociTEA tea maker is having difficulty circulating water, the likely cause is a build-up of limescale. 

Simply dissolve one tablet in a glass of water and run the tea maker using the 'black tea' setting. If it's been a while since you'd descaled your machine and the scale build-up is severe, you may need to repeat the descaling process a few times before circulation resumes again. 

VelociTEA Still Not Circulating
For machines that are still not circulating after a simple descaling process, we would recommend these steps:

- Fill kettle with water to minimum capacity
- Add a descaling tablet
- Set water to boil on Herbal setting
- Let machine heat up and boil water, watching to make sure the tablet dissolves (If not, we stir the water to dissolve the tablet)
- Let the solution sit a few hours to overnight
- Pour out the solution, and add plain water to minimum capacity
- Run 1-2 water-only cycles on herbal setting to test and clear machine
- Repeat if necessary

For heavy build-up, you may need to use more than the recommended amount of descaling tablets. We've seen machines that required up to three to clear the scale. 

Finally, a vinegar and water solution descaling is recommended if the descaling tablets on their own do not clear up the last of the clog.

We recommend descaling once a month or so depending on the hardness of the water/amount of tannins built up in the machine.
