Yes, cotton can generally be washed in hot water.
However, it's important to consider a few factors to avoid damaging your cotton items:
- Type of Cotton: Durable cotton items and linens are typically fine with hot water washing.
- Potential for Shrinkage: Hot water can cause some cotton fabrics to shrink, especially during the first wash. Consider pre-shrinking cotton fabric before sewing with it.
- Color Fading: Hot water can cause colors to fade, particularly in dyed or brightly colored cotton items.
- Water Temperature: While "hot" is relative, generally, hot water for washing machines is around 130°F (54°C) or higher.
- Best Practices: While hot water provides the deepest clean, especially when used with a quality detergent, using cooler water is often a safer bet to preserve colors and minimize shrinkage. The colder the water, the more gentle it is on the clothes.
In summary: While cotton can withstand hot water, carefully consider the garment's color, potential for shrinkage, and overall durability. If in doubt, err on the side of caution and use warm or cold water.
