Never Dry a Stain If a stain is still evident, do not place the garment in the dryer. The heat of the dryer makes the stain more permanent. Instead, reapply a laundry stain remover to the stain, let it soak for a half-hour or so, and then rewash. The same principle applies to ironing.
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.
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. 5.
Certain types of fibers, such as wool, cotton, silk, and some nylons are particularly susceptible to permanent staining from coffee, tea, wine, etc. Be aware of hot liquids, especially. Of course, bleach and household chemicals (see below) can cause permanent staining as well.
Once you have washed the item, check it to ensure the stain is completely removed, since drying can actually set the stain.
Similarly, you should always check a wet garment to see if the stain is gone before putting it in the dryer. The heat of the dryer can set the stain and make it permanent.

Drying the item before the stain is gone.
Great job if you get a stained item in the laundry soon after the staining occurs. But don't be too quick to transfer the item to the dryer! Just like with hot water, the heat of the dryer can set the stain permanently.
Unfortunately for everyone, some stains are permanent. They simply become part of the fabric.
If you leave it on for too long, the chemicals in the stain can start to break down the surface of the wood, causing it to flake off or peel. Sometimes, the excess stain may redissolve, giving you undesirable results.
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.
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.
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.

Most oil-based stains must dry for at least 12 hours before they are exposed to any moisture/rain; however, Ready Seal, if properly applied to prepped and dried wood, can get wet within a couple of hours, and it won't wash away. Oil-based stains will generally take 24-72 hours to fully cure.
You should also consider the type of wood you are staining, amount of stain you're applying, and weather conditions, like humidity, temperature, and air circulation. On average, wood stain takes about 24 to 72 hours to fully dry and cure, though you can typically add a second coat after about four hours.
Paint tends to last a little longer than most stains, coming in at around 8-12 years before you will likely have to repaint. Stain, on the other hand, typically has to be refinished every 5-10 years.

Chocolate is already tough to remove due to the combination of proteins, fat, and sugar, and if milk was used to make the cocoa the amount of protein and fat is even higher.
Hot water could change the stain's structure in a way that bonds it to the surface. This is especially true for protein and food-related stains on soft surfaces, such as fabric or carpet, Thomas says. Acids such as vinegar work to "cook" proteins, too. Use cool or lukewarm water and an enzymatic stain remover instead.
As previously mentioned, as hard water evaporates (versus getting wiped clean and dry), the minerals in the water are left behind, creating a hard water stain. Thankfully, avoiding this is very easy! Simply wipe water spills and splashes dry before they can dry by themselves.
Air-drying won't lock in stains
