In a washing machine, you can typically use two types of water:
Cold Water: Cold water is the most common and widely recommended type of water to use in a washing machine. It is suitable for most fabrics and colors, and it helps conserve energy since the machine does not need to heat the water. Cold water washing is particularly effective for removing stains like blood, chocolate, and mud.
Warm Water: Warm water can be used for slightly soiled clothes and items that require a bit more cleaning power than cold water can provide. Warm water is generally considered to be around 90°F to 110°F (32°C to 43°C). It can be effective for cleaning oily stains and some types of fabrics that may benefit from a slightly warmer temperature.
In most cases, you should avoid using hot water (above 130°F or 54°C) in a washing machine, as it can cause certain fabrics to shrink or colors to fade. Hot water should only be used for specific items that require it, like heavily soiled white cotton beddings or towels.
Always check the care label on your clothing items to ensure you are using the appropriate water temperature and washing instructions. Additionally, some washing machines have specific settings for different water temperatures and fabric types, so you can tailor the wash cycle accordingly.
