What are the best techniques for effectively using a drain cleaning brush to unclog pipes and prevent future blockages?

To effectively use a drain cleaning brush to unclog pipes and prevent future blockages, start by inserting the brush into the drain and moving it in a back-and-forth motion to dislodge debris. Repeat this process several times until the blockage is cleared. To prevent future blockages, regularly clean your drains with the brush and avoid disposing of grease, hair, or large objects down the drain.
