Can you leave drain cleaner in a drain overnight?

You generally should not leave harsh chemical drain cleaners in overnight as they can damage pipes (especially older metal or PVC), create hazardous fumes, or even solidify the clog, but some enzyme-based products or natural remedies (like vinegar/baking soda) are designed for overnight use; always check the product's specific instructions first. Strong chemical cleaners (like those with lye or bleach) work fast and should only sit for the time directed (usually 15-30 mins), then flushed with hot water.

Can you leave drain cleaner in overnight?

For many chemical drain cleaners, you can safely leave them overnight for tough clogs, as manufacturers often suggest this extended time for better results, but always check the specific product instructions; however, be cautious as prolonged contact, especially with older pipes, might risk corrosion, and for enzyme-based cleaners or DIY solutions (like baking soda/vinegar), overnight is often recommended, but flushing with hot water in the morning is crucial. 

Why do plumbers say not to use drain cleaner?

Damage to Pipes: Chemical drain cleaners work by creating a heat reaction that dissolves the clog. Unfortunately, this heat can also warp or damage plastic pipes and can corrode older, metal pipes. Over time, repeated use of these cleaners can lead to leaks and other serious plumbing issues.

Can too much drain cleaner damage pipes?

Drain Cleaner Can Damage Your Pipes

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).

It's generally not recommended to pour boiling water down the drain, especially in homes with modern PVC pipes, as the extreme heat can soften plastic, warp pipes, damage seals, and melt glue, potentially causing leaks or clogs to shift further down.
