The discussion centers around the volatility and corrosive nature of a cleaning product known as sanitary water, which contains 2.5% active chlorine. This concentration is significantly lower than straight bleach, which is about 8% hypochlorite. The product has a high pH of 11-12 and emits a strong bleach smell. Concerns are raised about its potential to oxidize metals and other materials in the home, especially when used in poorly ventilated areas. The conversation indicates that the product is commonly used in Brazil for bathroom cleaning, and there are worries about it spreading and causing corrosion on appliances and electronics. The thread concludes with a note that previous discussions on the topic have not provided satisfactory answers, leading to the decision to lock the thread.
