You will need about 150 grams of baking soda and you will need to pour it into the cup. After this step we take our vinegar again and add another 500 ml. The reaction will be foamy and bubbling: all incrustations will come off as if by magic. All impurities disappear.
vinegar and baking soda
You should leave it on for at least 10 minutes , then spread the foam everywhere again with the brush and scrub well. It would be a good idea to leave the vinegar and baking soda solution on for a maximum of 30 minutes and brush again a little until the tartar appears to have disappeared.
This makes sense for heavy incrustations that have been present for a long time, but with regular care the effort is even less. Even if only white vinegar is used , but only if the situation is not too “serious”.
