Depending on the product, the implementation method may be slightly different, but the most general process is as follows:
– Dissolve the sink drain cleaner powder in water.
– Pour the solution down the clogged drain/drain.
– Wait 60-180 minutes (depending on the type of powder and the blockage condition) for the powder to fully decompose the dirt in the sink.

– Rinse with clean water. Use a mixture of baking soda, vinegar and salt. Mix baking soda and salt in a 1:1 ratio, prepare 200ml of white vinegar.

Next, pour the mixture of baking soda and salt into the drain and then pour in the vinegar. Cover and wait about 1-2 hours. Pour more hot water into the drain to increase the ability to clean the dirt for the clogged sink.
