Why do plumbers say don't use Drano?

When your pipes are clogged, Drano will sit on top of the clog, continually reacting and generating heat until the clog dissolves. This can put a great deal of stress on your drains as the heat can cause PVC pipes to soften and even break or collapse.

What is the strongest thing to unclog a drain?

The strongest drain unblockers generally contain powerful chemicals like sulfuric acid, sodium hydroxide (lye), or strong enzymatic formulas, with Santeen Sulfuric Acid noted for high potency on organic matter, while Green Gobbler or Liquid-Plumr Industrial Strength gels are popular for hair and grease. However, for extreme clogs, professional-grade products like Hercules Clobber (sodium hydroxide) are used by plumbers, but these potent chemicals require extreme caution and personal protective equipment (PPE).

Why do plumbers say not to use drain cleaner?

Should I use hot or cold water with Drano?

Yes, Dawn dish soap can help unclog minor kitchen drain blockages, especially those caused by grease and oil, by using its degreasing power with hot water to break down and flush away buildup, but it's less effective for solid clogs like hair or food, and some experts warn it can even worsen severe clogs if grease re-solidifies further down.
