First step. The first thing to do is to cut off water and gas. The boiler should be completely switched off. Connect a hose to the water outlet, using a pump, you will remove and introduce a special mixture.
Step two. In a container, mix 250 ml of white vinegar with water. Pour into a container through which you can pour the mixture into the tube.
Caution: there are substances on the market that remove limestone. If you wish to carry out an internal cleaning of the pipes, you must contact a specialist technician.
Third step. You can clean the outside of the boiler and pipes with a vinegar-soaked cloth, rubbing vigorously to remove the most difficult stains.
Although hot water is a convenience and pleasure, it can also cause burns. We advise you to clean the boiler and hot water pipes very carefully.
