White Vinegar has great properties for cleaning away grease, as well as descaling abilities that are used in a wide range of cleaning and laundry tasks around the home. However the effectiveness of using White Vinegar to clear limescale is increased considerably when it is heated. Whilst some people simply pour the vinegar into the bottom of the machine there is a possibility of it being drained away before it has been heated. Research has found that the most complete way to use White Vinegar is to fill two containers on the top and bottom rack and to set the dishwasher on the longest, hottest wash. This way the White Vinegar is released gradually and the heat will ensure that the maximum amount of limescale is removed from the internal parts of the machine.
Dishwasher users may also want to carry on using the White Vinegar in the rinse compartment of the dishwasher for regular use - it gets rid of any water marks left on glasses with ease, as well as keeping limescale at bay!
