Cleaning  the floor  is undoubtedly one of the most boring and somewhat difficult household chores. Although it is easy to remove the dirt that accumulates on its surface, polishing the joints and avoiding leaving scratches is another matter.

The  dirt that accumulates between the joints  , almost always a mixture of dust, debris and mold, darkens them until they completely lose their original color. The result is a floor that, although new, immediately looks old.

Conventional cleaning products, the ones we normally buy to  wash the floor  , are certainly not suitable for cleaning grout lines.

Below we suggest the  most effective trick to lighten black grout  and clean the floor.

All you need is baking soda, a sponge, and some water.

Pour some baking soda into a container, add some water and pour it on the floor. Rub with the sponge, using a little force between the joints, then mop as usual.

It is not necessary to use a cleaning product. On the contrary, using a little vinegar as an alternative to floor detergent will help disinfect surfaces and perfume the house.

You will see that with this simple trick the floor joints will be like new again.
