Thus, it allows any activity to be carried out with water as it will collect and drain it, preventing moisture and unpleasant dirt from accumulating.
However, sometimes having a drain in the patio is not enough so that you can forget about the accumulation of moisture and dirt on the floor. If you want the system to work at all times, you will need to carry out maintenance to prevent it from clogging and not working properly. If the drain has already been clogged and you want to find out how to unclog a patio drain, at OneHOWTO we recommend that you continue reading this article where you will see 11 methods to achieve it.
Vinegar and baking soda
How can unclog a patio drain It is a question that, although it does not have a single answer, it does present different solutions. One of them is the use of baking soda and vinegar. For these products to be effective, follow these steps:
- With the help of a measuring container, add half the white vinegar and the other half, or a little less but at least a third of the total volume, of baking soda.
- This mixture will cause an immediate bubbling, so you will need to quickly pour it down the drain.
- With the effervescence created, it will facilitate the removal of dry leaves, dirt, hair and other traces of dirt in the pipes.
- Let the mixture work overnight or, at least, allow about 6 hours.
- The next morning, pour in a large amount of warm water to wash away all the debris that was clogging the drain.

Vinegar, baking soda, and plunger
The same baking soda and vinegar mixture together with factors such as gravity and pressure help to unclog the most clogged pipes following these steps:
- Mix baking soda and vinegar, as we explained in the previous point, to pour through the blocked pipe.
- Remove the grate if there is one, pour the mixture and place the cap on the pipe or something that serves to plug it.
- An hour later, fill a large basin or bucket or several with warm or hot water, remove the cap and pour it out.
- The water will finish moving the objects and dirt that were clogging the pipe and that had already been softened by the vinegar and baking soda mixture.
- To make the task easier, or if you see that the clog is serious, use a plunger while another person is pouring the water down the pipe. Thus, you have to alternate pouring water and using the plunger until you see that the drainage works well again and, therefore, there is no more clogging.
