Cold water extraction, also known as CWE, is a procedure that involves the extraction of a specific substance or more from a mixture utilizing cold water. The process is a type of procedure that is most commonly known as a fractional crystallization.

Fractional crystallization as part of cold water extraction involves the use of a mixture of different substances by dissolving the liquid into warm water followed immediately by a cooling of the mixture. The elements that are insoluble will then be precipitated from the water and the soluble compounds will be dissolved. This dissolved solution is separated via a decanting of the mixture or using a filtration procedure. The processes operate by exploiting the differences occurring in the concept of solubility as it pertains to different substances in low-temperature mixtures.

A Step-By-Step Guide For Cold Water Extraction (CWE)

CWE is a relatively fast procedure over and above the cooling down of the water in the mixture. Below are the steps used to complete the best cold water extraction guide:

1. Crush The Tablets

The first step is to crush the tablets into a fine powder. If, however, the medication presents in a capsule form it is necessary to pour the contents of the capsule into the water directly. If crushing the tablets, it is recommended that one place the tablet in a zip-lock bag beforehand and use a rolling pin to complete the crushing act.

2. Dissolve The Powder

Next, the powder needs to be dissolved in approximately 1/2 or 3/4 cup of warm water. Do not use boiling water as this can destroy the substance.

3. Allow The Mixture To Cool

After dissolving the powder, it is necessary to allow the mixture to cool for approximately 10-20 minutes while stirring frequently. Stirring needs to be completed to ensure the powder is fully dissolved. It is vital that the mixture is not cooled too quickly as codeine can be destroyed in this way.

Once the mixture has cooled to room temperature, it is necessary to cool the mixture further by placing the item in a freezer with a container lid. The mixture should be left in the freezer for approximately 20-25 minutes until it is cold to the touch; however, it must not be left to freeze until solid.

4. Filter The Mixture

The fourth step involves the act of filtration. Place a coffee filter, filter paper, or a cheesecloth over the top of the container and secure it with tape. Pour the mixture through the filter slowly and try to not touch the filter. Once the mixture has flowed through the filter, you should be left with a substance of a marshmallow-like density.

5. Squeeze The Filter

A step that can be conducted, but is not necessary, is to squeeze the filter. This is done to ensure that the majority of the moisture is removed from the substance.

6. Drink The Mixture

After filtering the substance, it is possible to drink the filtered item. The substance may be bitter, so it is recommended that you add a sweetener to the compound. Remember to throw away any remaining aspirin, ibuprofen or acetaminophen.

White shoes look really great when they are crisp and clean. However, it becomes important that you know how you will keep them clean so that they maintain that stylish and crisp appeal. Dependent on the material of the shoes, you can either wash them in the washing machine or hand wash them.

1. Clean Your Shoes By Hand

If you are washing your white shoes by hand, fill up a basin with warmed water. Now take a cloth and place it into the warm water. Lather a laundry detergent or Dawn Dish soap onto the cloth and rub the cloth over the white areas of the shoes.

Now scrub your shoes using a stiff-bristle brush. Concentrate on any stained areas to ensure all stains are removed. For tough stains you may want to use one of these techniques:

• A Magic Eraser is really great for those stubborn stains. Make sure that you use protective gloves before using this product.

• Another technique involves using toothpaste as an abrasive. Apply the toothpaste to a soft brush and then use circular motions over the stains.

Once you have finished cleaning your shoes, dip another cloth into clean water and proceed to wipe away all the soap from the surface of your shoes. Now lay the shoes on a dry and clean towel to air-dry. You may want to fill your shoes with paper towels. The towels will absorb any excess moisture and speed up the drying time. This method also assists the shoes in maintaining their shape while they dry.

2. Using A Washing Machine

If you want to clean white shoes by washing your shoes in a washing machine, start off by spot treating any stubborn stains. You can use a brush or a cloth to remove debris and dirt from the surface of the shoes. Follow this by spraying a stain remover like Shout onto the stains. Now brush the stains using a soft bristle brush.

If your shoes have shoelaces such as canvas shoes, make sure you take the laces out before placing your shoes into the washing machine. Avoid washing the laces with your shoes, unless the shoelaces are also white. This is because the dye in the shoelaces can transfer onto your white shoes.

Now add a small amount of your preferred laundry detergent and wash on a warm cycle. Avoid washing your shoes with other items of clothing or any other shoes. You should always check on the label that can usually be found inside the shoes for the preferred cleaning instructions. The label will be able to tell you if you can wash your shoes in a washing machine.

When the washing cycle is over you can choose to allow the shoes to air dry or you can put them in a dryer. Once again check the label to make sure that you are able to dry your shoes in a dryer. If the instructions state that you should not use a dryer, then place the shoes on a dry and clean towel to air dry.

If you let your shoes air dry, use paper towel inside the shoes to absorb any excess water and to minimize the drying time. This method also assists in helping the shoes to maintain their original shape while they dry.

You should only re-lace your white shoes once the shoes are completely dry. This step is very important when the shoelaces are another color other than white. This is because the dye in the shoelaces can stain your white shoes, especially when the fabric is still wet.
