No. The packaging of laundrypowder usually indicates the appropriate amount used for machine wash and hand wash, and it should be strictly followed.  If use excessive amount, it would not help cleaning and the residues would stay on the clothes and cause skin irritation.  If the detergent contains bleach, it will discolor the clothes and cause damage.

No. Bigger in size means larger in expansion and hollowness. The test on laundrypowder is calculated by weight concentration; therefore it is more important to look at the product's net weight, regardless of its volume.

No. There is no direct relation between sud and decontamination. For machine wash, existence of sud reduces friction during washing and thus the effectiveness. Sud is also not easy to rinse and only appeals to consumer psychology.  However, it is generally recommended to use detergent with high sud for hand wash, and appropriate level of sud for machine wash.

No. WayWay Super Concentrated Laundry Powder does not contain bleach and other corrosive agent; therefore will not cause damage or accelerate discoloring of clothing. For clothes that would discolor, use WayWay Oxicare Super Concentrated LaundryPowder or Liquid Detergent for better color protection.

There are many reasons causing discoloring of clothes, e.g.:

1. The dyeing of the garment is poor; it will discolor when washing with anylaundry  powder or even clean water, and it may stain other light-colored clothing when washing together.
2. Make sure to dissolve laundry powder completely before putting the clothes in. However, if the garment is exposed to dissolved laundry powder for a long time, the possibility of discoloring increases due to partial higher concentration of laundry powder.

No. It is not the case. The most commonly used enzyme-producing agents in laundrypowder are alkaline protease enzyme and alkaline lipase enzyme.

Alkaline protease enzyme dissolves protein type stains, such as sweat, blood, etc. Alkaline lipase enzyme dissolves fatty acid and ester-related stains, or generally called greasy stains.  The level of activity of these two types of enzyme is related to temperature, and the optimal level is 40℃. Higher or lower temperatures than that will decrease the activity of enzymes.

Also, protein can change its state.  An obvious characteristic is coagulation which reduces solvency. An example would be the solid state of an egg once cooked.  One of the conditions causing the change of state is high temperature, this also applies to protein type stains on clothing.  Therefore, if the water temperature is too high when washing, these stains will change state and stick to the fabric not to be removed easily.

There is. Laundrypowder cannot be used after a certain period. Under specified storage conditions, regular laundrypowder can be stored for two years or more. But those added with special ingredients may not last for two years.

To prevent losing its effectiveness, it is important to avoid moisture and exposure to sun light when storing detergent powder.  It should be stored in cool, dry places, especially if it contains enzyme and fragrance.  If the temperature is too high, its perfume will become volatile and enzyme will lose activity.  It is best to keep the detergent in a plastic bottle or tin can with a lid, so as to avoid hardening of laundrypowder or intake of synthetic fragrance once the perfume is evaporated.

Phosphor is an excellent fertilizer for plants. Some experts believe that phosphor is dissolved in water and discharged to water bodies (especially stagnant pools and lakes) with sewage after washing, providing nutrients for over-growth of algae (e.g. duck weed and water hyacinth) and bacteria underwater, thus reducing the oxygen content in water and damaging water quality, causing death of fishes and disrupting the ecology.

The main ingredient of softener is cationic surfactant, which is softening and anti-static. It sticks to the surface of garment to reduce friction, maintaining the original softness and pattern of the garment during washing and drying. It is anti-static and can prevent electric charge from accumulating on the surface of synthetic fabric and become "sticky", making the garment soft and fluffy.

No. Because softener has high adsorption capacity, if apply directly, it may not be evenly distributed and parts of the clothing would receive either too much (overly greasy) or too little application.  It should be diluted before use.

The reasons are:

1. Softener is most effective under neutral or acidic conditions, but laundrypowder is alkaline in nature.
2. Because softener has high adsorption capacity and creates a protective layer on the surface of fabric, detergent powder cannot easily penetrate into the fabric to remove dirt.
3. Softener has inhibiting effect on optical brightener; when used together with laundrypowder, both the brightening effect of detergent and its softening effect will be reduced.
4. The softening function of Silky Soft laundryPowder is specially developed by the lab of WayWay.

No, it is not.

Multi-purpose cleaner is best for items with smooth surfaces. Leather is absorbent in nature, and will be damaged if absorbs multi-purpose cleaner. Leather goods should be treated with respective cleaning products.

Yes. It can remove most stains, such as sauce, cooking oil, fruit, chocolate, milk. Ink stains must be treated with bleach.

No, it cannot. Liquid dish cleaner or other cleaners do not possess the following advantages:

1. Will not create side-effect to the glass surface
2. Will not scratch glass surface
3. Will not be foggy
4. Will not leave water mark or color mark after washing
5. Anti-static and prevent accumulation of dust

We recommend to use WayWay Professional Glass Cleaner.

It is suggested to use cotton cloth which is absorbent, soft, and its fibre will not fall out easily, so as to avoid scratching or leaving fibres behind on the glass.

Steps for good handwashing

1. Wet hands under running water.
2. Apply liquid soap and rub hands together to make a soapy lather.
3. Away from the running water, rub the palms, backs of hands, between fingers, backs of fingers, thumbs, finger tips and wrists. Do this for at least 20 seconds.
4. Rinse hands thoroughly under running water.
5. Dry hands thoroughly with either a clean cotton towel, a paper towel, or a hand dryer.
6. The cleaned hands should not touch the water tap directly again.
7. The tap may be turned off by using the towel wrapping the faucet; orafter splashing water to clean the faucet; or by another person.

Please note:

1. Towels should never be shared.
2. Used paper towel should be properly disposed of.
3. Personal towels to be reused must be stored properly and washed at least once daily.

When you wash in low water temperature, or wash clothing with stains (e.g. diapers), only using detergent is not enough to kill the bacteria. Wise Antiseptic can eliminate most bacteria in clothing.
