Drain cleaner
Two chemically opposite product families under one name, plus a third that is neither. Which one is in the bottle decides everything, including what happens if it meets the other.
Precautions
- Never mix with other cleaning products
- Wear gloves
- Wear eye protection
- Ventilate the area
- Keep away from children and pets
- Check the manufacturer's instructions
- Consider professional help
In detail
The UK poisons service divides drain cleaners into two categories that are chemically opposite, and it is the most useful thing anybody has said about the aisle. Enzymatic products contain bacteria and enzymes, and work slowly by digesting organic matter. Non-enzymatic products are strong acids or strong alkalis — sulphuric and hydrochloric acid on one side, sodium and potassium hydroxide on the other — and work in minutes by destroying it. The two families look identical on a shelf and behave nothing alike. An alkaline product turns fat into soap; an acidic one attacks the blockage and the pipe together. Some products generate heat when mixed with water, which is part of how they act on grease and fat and also a hazard in a confined trap. The service names two avoidable ways domestic users get splashed: pouring from a height, and overpouring into a drain that is completely blocked so the product has nowhere to go. On ingestion it is blunt, and its instruction is to contact the poison centre rather than attempt a home remedy. Two products from opposite families poured into the same trap is the worst version of the mixing accident, because the reaction happens out of sight.

What's in drain cleaner and what happens if you drink it?
National Capital Poison Center (Poison Control) · Poison or chemical-safety authority
Relied on for: That drain cleaners divide into enzymatic products containing bacteria and enzymes and non-enzymatic products that are strong acids or strong alkalis, that some generate heat when mixed, and that the two named splash routes are pouring from a height and overpouring into a completely blocked drain. (states this directly)
Verification: a person has read the passage relied on.
Read on — The composition section and the exposure-and-first-aid sections. Supports a narrower statement — our claim was reduced. This establishes the composition and the injury mechanism and NOT the mixing hazard, which CleaningHQ had expected it to carry. The article does not discuss mixing two drain cleaners, using a plunger after a chemical has been added, or what to do with a drain holding an unknown product. Those questions are therefore answered from the general never-mix position and the standing refusal in the mixing model, not attributed here. What it does newly support is the completely-blocked-drain splash case, which is exactly the situation a reader is in when they reach for a second product.
