You’re not alone: fight slow-running drains with the dual-formula action of Liquid-Plumr™ Clog Destroyer Plus+ Foaming Clog Fighter™. Together, two powerful liquids activate on contact to create a dense, blockage-busting foam that cleans pipe walls, maintains garbage disposals and clears clogs.

This product is designed to pour through standing water. However, it is formulated to work effectively on slow flowing drains. For particularly stubborn clogs that cause standing water in drains, Liquid Plumr recommends using Liquid-Plumr™ Pro-Strength Urgent Clear Gel.

This product is formulated to work effectively on slow drains. Slow drains are sometimes caused by partial clogs that form at or below the stopper. In this situation, this product will remove the clog and fix the slow drain. Stubborn conditions may require a second treatment.
For best results, Liquid Plumr recommends using the entire bottle for every clog problem.
Wait at least one hour after pouring this product down the drain before flushing with water. If you have an especially slow drain, you can safely let the product sit overnight.
Just remove the cap and pour the entire bottle into the drain. The liquids in the different chambers will combine in your drain.
The product contains two chambers with powerful liquids. One chamber contains a thickened formula that dissolves hair and gunk. The other contains a foaming agent that carries the formula throughout the entire pipe. The two liquids combine to create a deep cleaning foam that clears your slow drain and cleans your pipe walls.
When using this product, foam may form in the sink as the two liquids combine. This shows that the pipe is full of the active foam. Follow normal usage directions by waiting one hour and rinsing with hot tap water. It is also normal not to see foam. It depends on your clog and your particular sink.
Ingredients include sodium hypochlorite, sodium hydroxide, biodegradable surfactant, and sodium silicate (corrosion inhibitor). Contains no phosphorus.
Use this product whenever water stops flowing into your drain, which is characterized by standing water. You may also use it whenever you notice a slow-running drain.
This product is very effective on full clogs and slow flow drains, and with regular monthly use can help keep your pipes flowing freely.
If your drain does not improve Liquid Plumr recommends trying another bottle of this product. However, if the problem continues to persist, you should call a plumber, as there are some plumbing situations that even Liquid-Plumr™ cannot fix.

What should I do if I come in contact with either the foam or the liquid in Liquid-Plumr™ products?: If in eyes, flush immediately with water for 15 minutes. If wearing contact lenses, remove first. If on skin, wash immediately with water. If swallowed, drink a full glass of water. Do not induce vomiting. In all cases, call a doctor or poison control center immediately.

Warning: Do not use Liquid-Plumr™ products with ammonia, toilet bowl cleaners or other non-Liquid-Plumr™ clog removers, as splashing or the release of hazardous gases may occur. Liquid Plumr does not recommend using Liquid-Plumr™ products with non-Liquid-Plumr™ products. It is safe to use any Liquid-Plumr™ product in the same drain.
