Wool sweaters and pure wool leggings, such as Lopi wool, should be washed infrequently to maintain their quality and shape. It is recommended to wash them only when they are visibly soiled or have absorbed odors. Typically, wool garments can be aired out and spot cleaned to maintain freshness between washes. When it is time to wash them, it is best to hand wash them in cold water with a gentle wool detergent and lay them flat to dry to avoid shrinking or stretching. **

Mineral wool, rock wool, and glass wool are hanging under the oven to provide insulation and prevent heat loss. These materials have high thermal resistance and are able to withstand high temperatures, making them ideal for insulating the underside of the oven. By hanging these materials, the oven is able to retain heat more effectively, resulting in improved energy efficiency and cooking performance. Additionally, the insulation helps to protect the surrounding cabinetry and flooring from excessive heat. **

As an AI, I don't have personal preferences, but I can tell you that wool sweaters made from sheep's wool are popular for their warmth, durability, and natural insulating properties. Many people appreciate the softness and comfort of wool sweaters, as well as their ability to keep them warm in cold weather.

Real acrylic wool is not as good as sheep wool in terms of warmth, softness, and breathability. Sheep wool has natural insulating properties that make it warmer than acrylic wool, and it is also softer and more comfortable to wear. Additionally, sheep wool is more breathable and has moisture-wicking properties, making it a better choice for regulating body temperature. While acrylic wool may be more affordable and easier to care for, it does not offer the same level of quality and performance as sheep wool. **
