There is no true answer for this question as it depends on the fabric and the type of stain will affect which type of water is best to use. For most items it can truly be said that hot water is the best for removing stains on all forms of fabric, however if the stain contains protein like a blood stain for instance then cold water is better, as hot water heats up the protein allowing it to be absorbed more easily by the fabric causing the stain to worsen.
Again for most clothing the hotter the water, the cleaner the clothing will be. Most linens and white clothing are washed in hot water to remove germs and heavy soil. However, many of our clothes won't come out looking very nice if they are washed in hot water. Hot water tends to make some clothing shrink, wrinkle, and fade.
However for most people the majority of their laundry is washed with warm water. Warm water is actually a mix of hot and cold. Some machines mix the hot and cold water 50-50, although newer machines mix 60-40. Warm water is usually the best choice for permanent press and jeans. It allows good cleaning action without as much fading, wrinkling, and shrinking.
Cold water is usually used for delicate items, or items with instructions to be washed in cold water. If your cold water items are heavily soiled or dirty, you need to be especially diligent about checking and pre-treating for stains. You may also have to wash the items for longer, or allow them to soak before washing if they are heavily soiled.
Pre-treating the stains will allow the clothing to get clean even if it needs to be washed in warm or cold water. Take the time to pre-treat for stain removal before the clothes are washed and you will have a much better chance of the clothing coming out clean and stain-free.
