Do you wash cast iron with soap and water?

Because other cookware cleaning techniques like scouring or washing in a dishwasher can remove or damage the seasoning on a bare cast-iron pan, these pans should not be cleaned like most other cookware. Some chefs advocate never cleaning cast-iron pans at all; simply wiping them out after use, or washing them with hot water and a stiff brush. Others advocate washing with mild soap and water, and then re-applying a thin layer of fat or oil. A third approach is to scrub with coarse salt and a paper towel or clean rag.

As with other cast iron vessels, a seasoned pan or dutch oven should not regularly be used to cook foods containing tomatoes, vinegar or other acidic ingredients, as these foods will eventually remove the protective layer created during the seasoning process. Cast iron ovens are best suited to cook food high in oil or fat, such as chicken, bacon, or sausage, or used for deep frying. Subsequent cleanings are usually accomplished without the use of soap. Detergent soaps and dishwashers can remove the seasoning on cast iron, so some cookbook authors recommend only wiping the pans clean after each use, or using other cleaning methods such as a salt scrub or boiling water. The protective layer itself is polymeric and not very susceptible to soaps, and many users do briefly use detergents and soaps. However, cast iron is very prone to rust, and the protective layer may have pinholes, so soaking for long periods is contraindicated as the layer may start to flake off.

Removal of soap and water from the clothing after washing was a separate process. First, soap would be rinsed out with clear water. After rinsing, the soaking wet clothing would be formed into a roll and twisted by hand to extract water. The entire process often occupied an entire day of hard work, plus drying and ironing.

Clothes were washed manually, by rubbing and sometimes striking them against a hard surface with soap. The aim was to do penetrate the mix of water and soap between the fibres of the fabric to pull-out the dirt. The slabs to wash the clothes were slabs of natural stone chosen to present a fine and relatively flat surface. The small rounded irregularities could help of friction in the washing process.

Iron is more prone to rusting than (tinned) copper. Cast iron kitchen utensils, in particular, are however less prone to rust if, instead of being scoured to a shine after use, they are simply washed with detergent and water and wiped clean with a cloth, allowing the utensil to form a coat of (already corroded iron and other) material that then acts to prevent further corrosion (a process known as seasoning). Furthermore, if an iron utensil is solely used for frying or cooking with fat or oil, corrosion can be reduced by never heating water with it, never using it to cook with water, and when washing it with water to dry it immediately afterwards, removing all water. Since oil and water are immiscible, since oils and fats are more covalent compounds, and since it is ionic compounds such as water that promote corrosion, eliminating as much contact with water reduces corrosion. For some iron kitchen utensils, water is a particular problem, since it is very difficult to dry them fully. In particular, iron egg-beaters or ice cream freezers are tricky to dry, and the consequent rust if left wet will roughen them and possibly clog them completely. When storing iron utensils for long periods, van Rensselaer recommended coating them in non-salted (since salt is also an ionic compound) fat or paraffin.

Vacuum your whole entire house especially where you think the infestation is. Throw away any items that are already infested. Wash all your clothing and fabrics with soap and hot water. If you want, you can go the extra length by steam cleaning your furniture and carpentry.

Certain types of fabrics need to be re-treated to maintain water-repellency, as fluoropolymers decompose over time when exposed to water and chemicals. Washing the garment with harsh detergents usually accelerates DWR loss; in addition, soaps often leave a residue which attracts water and dirt. On the other hand, rain water or salt water affects DWRs less significantly. Affected garments can be treated with a 'spray-on' or 'wash-in' treatment to improve water-repellency. In some cases heat treatment can reactivate the factory applied repellent finish and aid in the repelling of water, and other liquids such as oils. On the other hand, some DWR products do not require heat treatment to be activated, and sometimes DWR treatments can be revitalized simply by washing the fabric with a suitable cleaner.

The equipment typically includes new syringes and needles, alcoholic swabs, rinse eye drops as sterile water, filter (cotton or syringe filter like Sterifilt), tourniquet, and a clean spoon or Stericup. In order to minimize the chance of bacteria or viruses entering the bloodstream, people are advised to wash their hands with soap and warm water. However, as people do not always have access to hot water and soap when they are injecting, the philosophy of harm reduction seeks to find the most realistic and reliable option that drug users will take; a process that takes much time or access to material is unlikely to be used frequently. Alcohol swabs are commonly distributed with injecting equipment, and while they are less effective than hand washing, their use is more effective than nothing. Any sharing of injecting equipment, even tourniquets, is highly discouraged, due to the high danger of transmitting bacteria and viruses via the equipment.

In developing countries, hand washing with soap is recognized as a cost-effective, essential tool for achieving good health, and even good nutrition. However, a lack of reliable water supply, soap or hand washing facilities in people's homes, at schools and at the workplace make it a challenge to achieve universal hand washing behaviors. For example, in most of rural Africa hand washing taps close to every private or public toilet are scarce, even though cheap options exist to build hand washing stations. However, low hand washing rates rather can also be the result of engrained habits rather than due to a lack of soap or water.

A seasoned pan has a stick-resistant coating created by polymerized oils and fats. Seasoning is a process by which a layer of animal fat or vegetable oil is applied and cooked onto cast-iron or carbon steel cookware. New cookware should be vigorously washed in hot water with a strong detergent to remove any casting oils from the cookware's surface. A light coat of oil is applied and the cookware is placed upside down in an oven above a large pan (to drain for an hour), the pan can now be removed, then the oven set to 350 degrees Fahrenheit (180 degrees Celsius) and baked for 30 minutes. Some cookware comes pre-seasoned from the factory.
