Hot water will set some stains, particularly protein based stains. Use cold or warm water on these before washing in hot water. Always test to be sure that a stain removal product will not damage fabric by applying to a small part of the fabric that is not easily seen.
Typically, cold water works great on blood, as well as food, beverages and water-based paint, while hot water works best on protein-based stains. Unfortunately, there's no golden rule to stain removal. For example, most food stains should be soaked in cold water, unless it's egg, mustard or a tomato-based product.
Protein stains such as dairy, blood, egg, glue, and white deodorant marks should always be washed in cold water. Hot water can actually cook the protein, causing it to absorb into the clothing fibres, and making it almost impossible to remove. Cold water helps lift the stain without setting it.
When removing accidental stains, knowing whether hot or cold water is best can be challenging. While both temperatures can be effective for stain removal, they can also permanently set a stain, making it nearly impossible to remove.
Flushing a fresh stain with hot water may seem obvious, but it can have the opposite effect. Hot water can permanently set some stains, particularly those that are protein-based, like blood. Instead, always use cold water.
Cold water is fine for most clothes and other items that you can safely put in the washing machine. It can remove many stains from clothing, including grass on your kid's jeans or makeup smudges on a sweater. Delicate fabrics (lace and silk) and dark, colorful fabrics actually do best in cold water.
Heat can set stains permanently. Once you toss the item into the dryer, the stain is set for good. If the stain remains after the first wash, pre-treat and wash again before drying to try and remove the stain.

Issues with Fabric Softener
The use of fabric softeners can lead to stained clothing in the washing machine. In most cases, people use too much fabric softener, which then doesn't have ample room to spread throughout the washer.
If you have overloaded the washer, the clothes won't be able to move around as freely, and therefore it's less likely to eliminate dirt and grime from all the surfaces. In order to avoid overloading, make sure the clothes aren't packed in too tightly and that the washer tub is no more than three-quarters full.
Most stains can be applied from about 50° F to 90° F — but many people don't realize this range refers to the temperature of the wood surface, not the air. A day that's 70°F and sunny can push deck surface temperatures above 90°F leading to application challenges and shortened open times.
1. Apply white vinegar directly to the stain, let it soak in for a few minutes (don't let it dry). 2. Wash the garment in your machine using the hottest water the fabric can tolerate.
The longer a stain is left untreated, the less likely it is to be removed. When a spill first occurs, it sits on the surface of the fabric, but over time, that spill can start to react with the fabric causing the fabric to actually change colors.
Stick with warm if that's best for the fabric. Hot water should be between 120 and 140 degrees F, warm water between 85 and 105 degrees F and cold water between 65 and 75 degrees F. Water below 60 degrees is too cold for many detergents to be helpful in removing oily stains.
Cold water works best on highly pigmented foods, such as cheese, jelly and jam, soy sauce, baby food, and mustard. Hot water might actually set natural or added food dyes. If you get to the food immediately, the cold water should rinse out the stain pretty quickly.
Water stains can be removed relatively easily from washable clothing.
One of the most common causes is using too much detergent. If you add too much detergent, the fabric will react with the washing powder, leaving behind brown flakes. Another common cause is using too much Fabric softener. The product is made of oil, and when you use too much, it causes a stain.
If you feel like it's your only option, though, start with diluted oxygen bleach and move on to chlorine bleach if necessary. Really old, stubborn stains sometimes respond best to liquid glycerin. Rub it in, let it soak and then launder again.
Can baking soda remove old stains? Yes, baking soda can lift stains from many kinds of fabric. Arm & Hammer suggests making a pre-treating paste made of 6 tablespoons of baking soda and ⅓ cup warm water. Be sure to test it on the garment first, then apply the paste to the clothing, let dry and put it in the wash.
White clothes should generally be washed using hot or warm water. Using higher temperatures for whites can effectively help remove stains and bacteria.
Use warm water
White denim should be washed in warm water to help remove germs and dirt.
Stains that go unnoticed or untreated can set in further with a typical heated dry cycle, so it's best to opt for air drying as you work on removing sweat stains from clothing.
Depending on the type of stain you are using, most stains are dry and cured within 24 hours to 48 hours. After that time, it's safe for additional coats or to apply polyurethane or the sealer of your choice.
If you find a stain on an item that has been through a hot dryer, it doesn't have to be permanent. By using the right laundry products and the right technique, stains that have been dried do come out. Back-to-school cleaning.
Permanent or stubborn stains are typically caused by spillages that are not removed quickly after they occurred. The key to handle such challenging spots is to remove the stains immediately after you discover it.
