Cleaning

Semen stains can be detected using a forensic light source that causes the stains to fluoresce under certain wavelengths of light. Additionally, chemical tests such as the Acid Phosphatase Test or the Microscopic Examination Test can also be used to detect the presence of semen stains on a surface. DNA analysis can provide confirmation of the presence of semen and identify the individual it came from.

Barry Scott of 'Cillit Bang' (a household cleaning product) fame says that if you leave the penny is Cillit Bang for 15 seconds it will clean it. You can also leave the Penny is a glass of Coca Cola for a few hours. I've done that and it does work.

To clean raw cotton, start by removing any debris or foreign particles by hand. Then, soak the cotton in a mixture of water and mild detergent, gently agitating the mixture. Rinse thoroughly with clean water and allow it to air dry completely. Avoid wringing or twisting the cotton to prevent damage to the fibers.

One way to remove a stain from a permanent marker on jeans is to dab rubbing alcohol onto the stain with a cotton ball. Blot the stained area until the marker lifts off, then rinse with cold water and wash the jeans as usual. Repeat the process if necessary.

To remove wax from a wall, place a cloth or paper towel over the wax and run a warm iron over it. The heat should melt the wax, allowing it to be absorbed by the cloth. Repeat the process with a clean cloth until all the wax is removed.

One option is to blot the stain with a damp cloth or paper towel to remove as much of the semen as possible. Then, sprinkle baking soda or cornstarch on the stain and let it sit for a few hours to absorb the remaining moisture and odor. Finally, vacuum or brush off the powder before reusing the sheets.

To remove white streaks left by Bona refresher on a hardwood floor, try wiping the floor with a mixture of vinegar and water or a wood floor cleaner. You can also try buffing the affected area with a microfiber cloth to blend the streaks with the rest of the floor surface. If the streaks persist, you may need to lightly sand and refinish the area.

The chemical FORMULA for most dry cleaning fluid is Cl2C=CCl2,aka tetrachloroethylene, aka PERC.

Alternative dry cleaning products include:

hydrocarbon mixture such as DF-2000 and EcoSolv

Dibutoxymethane - formula C3H8O2

Liquid silicone - formula [(CH3)2SiO]5.

Brominated solvents - typical formula CH3CH2CH2Br.

Supercritical or liquid Carbon Dioxide - formula CO2

First break up any pieces that you can remove with a screwdriver leaving just what is actually stuck to the carpet. Next use several paper towels folded and a medium hot iron and place towels over wax and place iron on top of the towels for a few minutes, you will notice the wax melting and being absorbed into the towels. Keep repeating this process until no more wax can be absorbed into the towels. Remember faster is not better, adding more heat will melt the carpet fibers as well as the wax so be patient.

The weakest paper towel is typically one-ply paper towels, which are thinner and have less absorption capacity compared to two-ply or three-ply paper towels. They tear easily and may not hold up well to wet or heavy tasks.

Get the diapers when they are wet out of the wash and let them dry out in the sun. Seems to be very effective for diaper blowouts. Or you can try rubbing alcohol and deodorizers like baking soda.

Clothes may weigh more after being washed due to water absorption into the fabric. When clothes are washed, they absorb water, which adds weight to the fabric until the water evaporates during the drying process.

Engine coolant is a chemical compound. It consists mainly of water, but water freezes too easily so an antifreeze is added. This helps prevent the coolant from freezing on winter days and it also raises the boiling point which is helpful. An antifreeze contains mainly ethylene, but also has some methanol and propylene. The water and antifreeze make up around 90% of the coolant. The rest of it is chemicals to prevent rust and corrosion (redox reactions) occurring. In other words... Coolant contains: Water - 60% Antifreeze - 30% Others - 10%

If you magnify or look very closely to the shape of the threads that make up the cloth, they are organized like a series of tiny squares. Stains, such as protein stains, get stuck in these tiny squares.

Protein is a large insoluble molecule. An enzyme, such as protease, in the washing powder breaks down this protein into smaller more soluble molecules.

The new molecule is soluble, thus when the water in the washing machine rises, or you rinse the piece of cloth, the water dissolves this molecule and carries it away from the cloth. This leaves the square spaces between the threads clean and empty of stains.

This means that washing powders with enzymes can efficiently remove protein stains such as blood.

I am not sure but you might try soaking the affected area with nail polish remover but it might stain the shirt the color of the paint. If that happens you could possibly then try removing the stain with bleach.

The trick with mold in the crawl space is killing the mold root. Bleach does NOT do this, it only kills the surface mold. The best solution is to use an organic mold killer found at most home improvement centers. One of the more popular brands is concrobium. There is more information about crawl space mold at this website- crawlspaceinfo.com. Scroll down click on the mold link or see related link below. Hope this helps!

I dont all i know is that this question is due tomorrow and i need an ans

You can use hairspray to remove ink from clothing. Spray enough hairspray on the stain so that it penetrates the material. Then rub the fabric on itself. This helps to release the ink from the fibres. Then rub some handsoap onto the stain and rub into the fabric. Scrub the fabric and rinse. Repeat if necessary. This works best on cotton, polyester, and denim.

To remove red dye from a white blouse, you can try soaking the stained area in a mixture of cold water and bleach. Alternatively, you can use a stain remover specifically designed for colored stains. It's important to act quickly and avoid heat, as it can set the stain further.

To remove dark nail polish from carpet, first blot up as much as possible with a clean cloth. Then, apply a small amount of nail polish remover onto a clean cloth and gently dab at the stained area, working from the outside in to prevent spreading. Repeat until the stain is lifted, then rinse the area with water and blot dry.

You can remove hard water stains from glassware by soaking them in a vinegar and water solution, then scrubbing with a soft sponge. You can also try using a mixture of baking soda and water to scrub away the stains. Additionally, you can use a commercial glass cleaner specifically formulated for hard water stains.

One common method to remove permanent marker from surfaces is to apply rubbing alcohol or acetone onto a cloth and gently rub the stained area. Another option is to use a whiteboard marker to draw over the permanent marker, then wipe both marks away with a cloth.

To clean up lighter fluid spilled on concrete, first absorb as much of the fluid as possible with paper towels or rags. Then, scrub the area with a mixture of water and dish soap or a commercial degreaser. Rinse thoroughly with water afterwards.

Cement tile grout is typically composed of a mixture of cement, sand, and often additional additives such as polymers for flexibility and water retention agents to improve workability. Water is added to this mixture to create a spreadable paste that is used to fill the gaps between tiles.
