Does tea stain cleaner cause harm to the human body

1. Common ingredients and functions:

The ingredients of tea stain cleaning agents usually include surfactants, chelating agents, oxidants, etc.

Surfactants can reduce the surface tension of water, allowing cleaning agents to better contact and remove tea stains; Chelating agents can bind with metal ions in tea stains to prevent their re deposition; Oxidants can decompose tea stains through oxidation.

For example, citric acid is a common chelating agent that can form soluble complexes with metal ions such as calcium and magnesium in tea stains, thereby removing tea stains.

Sodium percarbonate is an oxidant that decomposes into reactive oxygen species upon contact with water, and has strong cleaning ability.

2. Security assessment:

Generally speaking, tea stain cleaners produced by legitimate manufacturers undergo strict quality testing, and their ingredients are relatively safe under normal usage conditions. These cleaning agents usually comply with relevant national standards and have low toxicity to the human body.

However, if the tea stain cleaner contains some highly irritating chemicals such as strong acids, alkalis, etc., it may cause harm to the human body. For example, strong acids may corrode the skin and respiratory mucosa, while strong alkalis may cause burns.

When using tea stain cleaner, strictly follow the instructions in the product manual. This usually includes diluting the cleaning agent to an appropriate concentration, soaking for an appropriate amount of time, and rinsing thoroughly with clean water after use.

For example, for some tea stain cleaning agents that need to be soaked, the soaking time should be determined based on the severity of the tea stain and the concentration of the cleaning agent. Generally, it should not exceed the specified time range to avoid potential harm to the human body caused by residual cleaning agents.
