Using a plunger can create pressure to dislodge the blockage in a sink. A mixture of baking soda and vinegar can also react to break down the clog. Ignoring the clog will not make it go away and may lead to more serious problems. Using a hairdryer to heat the pipes is not an effective way to unclog a sink. Pouring more water down the drain when there is a clog may cause the water to overflow.
