because water is dense than grease, is stays separate from the grease. however, when a detergent is applied, it acts as an emulsifier, allowing the grease to mix with the water and come of the clothing.
Grease is less soluble in cold water compared to hot water, which makes it more difficult to break down and remove from fabrics. Hot water helps to melt the grease and allow it to be lifted away from the cloth. Using cold water alone may not effectively remove the grease stains.
Once any material (wine, food, grease etc) has touched any fabric (carpet, upholstery, clothing etc) a stain begins to form. The trick of stain removal is to get to the stain as fast as possible, before it has time to set. For example, when wine falls onto your carpet much of the initial spill is picked up right away. If the homeowner chooses not to hire a professional cleaner, but instead leaves the stain alone, the wine will bond with the fabric. The stronger the bond, the harder the stain becomes to remove. Some things can prevent the stain from setting, like cleaning products. If you have a wine stain on an item of clothing, and you put the item of clothing into the dryer before the stain is removed, then the heat from the dryer will strengthen the chemical bond of the stain and make the stain harder to remove. One very important thing in stain prevention is to always blot, and never rub an area with a stain. Rubbing the stain, even if you're trying to remove it, will rub the stain into the fabric, and make it harder to remove. Time, heat, rubbing and improper stain removal will always make stains harder to remove.
Dry cleaning uses a chemical solvent to dissolve stains without the use of water, which can sometimes cause more damage to certain materials. The solvent is able to break down greasy or oily stains that water alone might not be able to remove. Additionally, dry cleaning involves a specific cleaning process that can protect delicate fabrics or garments that are not water-safe.
Some stains are more difficult to remove because they are oil-based or contain pigments that water alone cannot break down. Water may not be able to penetrate the stain or dissolve the molecules, making it harder to lift the stain from the surface. In these cases, using specialized cleaning products or techniques may be necessary to effectively remove the stain.
Water alone is not very effective at removing stains because most stains are not soluble in water. Water is a polar molecule and does not possess the ability to break down the chemical bonds in stains. To remove stains effectively, a cleaning agent or solvent that can break down or dissolve the stain molecules is usually needed.
Grease is less soluble in cold water compared to hot water, which makes it more difficult to break down and remove from fabrics. Hot water helps to melt the grease and allow it to be lifted away from the cloth. Using cold water alone may not effectively remove the grease stains.
It is true that water alone cannot remove greasy stains from clothing. Alcohol usually can because it is a solvent.
Instead of detergent, spray a little WD-40 or lighter fluid onto the clothing. WD-40 is effective in removing grease from some surfaces, as are some lighter fluidsPerform a spot test on an inconspicuous area of your clothing before attacking the stain with the WD-40 or lighter fluid. It's better to be safe than sorry.Let the WD-40 or lighter fluid set into the clothing for 20 minutes.Wash out the WD-40 or lighter fluid by thoroughly soaking the clothing in warm water.Wash the clothing, alone with laundry detergent. Follow washing instructions on clothing label exactly.When ready to dry, allow the clothing to air-dry. Drying in the extremely hot mechanical dryer may cause any lingering oil or grease to set into the clothing.

There are worse things I could do
Oil is hydrophobic or 'water-hating'. It doesn't mix with water so when the water goes away, the oil doesn't follow. Soap, on the other hand, mixes with the oil so when it goes away so does the oil.

leave them alone.
it means that when you alone it is difficult for you to get disease or to be killed by anyone
