With this type of cookware, a little proper maintenance goes a long way, and one of the few food prep acts you should never do in your cast iron pan is boil water. Simmering a little sauce or marinade is nothing to sweat. What you want to avoid, however, is an extended roiling boil, like when cooking pasta or beans.
The takeaway? It's safe to cook tomato- and wine-based sauces in cast iron, but you should save the vinegary pan sauces for stainless-steel pans—or dilute the vinegar (or citrus) with water or stock. 4.

Never shock a hot cast iron pan with cold water because it can crack. 5. Don't soak or leave a wet pan in the dish rack because this will promote rust. Always dry it over a low burner, then re-season with a quick wipe of shortening or vegetable oil on a cloth or paper towel before storing.

Background: Coal tar and bitumen have been historically used to coat the insides of cast iron drinking water mains. Polycyclic aromatic hydrocarbons (PAHs) may leach from these coatings into the drinking water and form a potential health risk for humans.
-Can You Boil Iron Out of Water? No, you cannot. Iron always exists in water in dissolved or precipitated solid form, and boiling only kills bacteria and viruses in well water through high temperatures. Just as you cannot remove sugar dissolved in water or insoluble sediment by boiling.
Clean Your Drain
Boiling Water: Pour boiling water down your drains to wash away gnats and their eggs. Baking Soda Solutions: Use a mixture of salt, baking soda, and white vinegar to foam away bacteria in your pipes. Chemical Cleaners: For intense infestations, consider using a chemical cleaner like Drano.
In many cases, you should avoid cooking acidic ingredients such as tomatoes, lemon juice, wine, and vinegar in your cast-iron skillet.

Pasta will ruin your skillet's seasoning
And that's precisely why it should stay out of your cast iron skillet. According to ranch cook and YouTuber Kent Rollins, boiling water for extended periods of time in your skillet will negatively affect its seasoning.
Reason: Copper does not react with cold water, hot water or steam. However, iron reacts with steam. If the hot water tanks are made of steel (an alloy of iron), then iron would react vigorously with the steam formed from hot water.
Don't boil water in a wok, whether it is nonstick or not. Woks are not made for this. If it is a carbon steel wok that is well seasoned, boiling water in it strips away the seasoning. Further, nonstick stir fry pans and sauté pans are made to cook with oil, so constantly cooking boiling water weakens the nonstick.
No, they aren’t the same. Boiled water is simply water that has had the temperature increased until it reaches its boiling point. This kills a host of bacteria that can make a person sick. Distilled water is water that has been stripped of all impurities, including minerals and microorganisms.

While boiling does purify water and reduce certain levels of bacteria and other microorganisms that could give it an odd taste or smell, repeatedly doing so could cause a buildup of minerals which can actually make the water worse tasting than before.
Iron filters (such as a manganese greensand filter) are a common treatment for red-water iron levels up to 10-15 mg/L. Aeration (injecting air) or chemical oxidation (usually adding chlorine in the form of calcium or sodium hypochlorite) followed by filtration are options if iron levels are more than 10 mg/L.
Rapidly boiling water can cause the seasoning to lift from a cast iron pan, not only leaving it vulnerable to rust, but also releasing little black flakes of the seasoned surface into your food.
With proper care cast iron cookware can withstand a lifetime of use. Actually several lifetimes as these cast iron pans and dutch ovens are often passed down from generation to generation. Taking care of cast iron cookware is as easy as 1 – 2 – 3.
