What is really blocking your sink drain?

One clogged drain does not form overnight. Residues build up gradually until a complete blockage is created.

The hair : It's the number one culprit in bathroom sinks. The hair intertwines and forms a compact mass that holds everything else together.

Soap and toothpaste : These products leave sticky residues on pipe walls. Over time, this layer thickens and attracts more debris.
