What should be done with an unlabelled cleaning product?

Disposing of an unlabelled cleaning product is the safest approach. Without clear labeling, it's impossible to know its composition, potential hazards, or safe usage guidelines. Using unlabelled products can pose risks such as chemical reactions with other substances, improper application leading to damage, or health hazards due to exposure to unknown chemicals. Discarding ensures that no one uses the product unknowingly and avoids any accidental harm or damage that could result from unintended uses or combinations with other chemicals.

In contrast, approaches like using it cautiously or testing in a small area carry risks, as they could lead to mishaps without knowledge of the ingredients. Similarly, trying to use the product solely on tough stains does not mitigate the inherent dangers associated with an unknown substance. Therefore, discarding the unlabelled cleaning product is the most prudent and responsible action to ensure safety.
