Q
A highly stained carpet, how can it be cleaned?
A.
In the case of a highly stained carpet, shampooing alone is not enough. We have to mix in the shampooing maching 50% Rotobuff (carpet shampooing chemical) along with 50% Solo (carpet stain remover) in hot water and do the process of cleaning.
Q
How to remove oil or grease stains from fabrics?
A.
Whether it's a cooking, automotive or lubricating oil mark, the sooner you deal with a greasy stain, the better the outcome.
1.Apply an absorbent such as talcum powder or cornstarch to the affected area, then brush away. If the stain is heavy or old, proceed to Step 2; if fresh, skip to Step 3.
2.Place stain facedown on paper towels. Blot back of stain with a dry-cleaning solvent. Replace paper towels as they soak up the stain.
3.Spray with laundry pretreatment.
4.Wash in the hottest water that's safe for the garment.
5.Air dry.
Q
What is the use of Chlorine Bleach?
A.
Chlorine bleach, used to boost the cleaning power of regular laundry detergents, is ideal for removing tough stains and occasionally whitening fabrics, but improper and long-term use may take its toll on fabric life and colors. Pretest on the garment for color- and fabric-steadfastness before using it on a stain.
Q
I have noticed mineral deposits on my cooking dishes and rings of insoluble soap scum in my bathtub, why is that?
A.
These are not signs of poor housekeeping, but are rather signs of hard water from the municipal water supply. Hard water is water that contains cations with a charge of +2, especially Ca2+ and Mg2+. These ions do not pose any health threat, but they can engage in reactions that leave insoluble mineral deposits. These deposits can make hard water unsuitable for many uses, and can effect the efficiency of the cleaning chemicals when mixed with water.
Q
Is it true that the water has an amazing affect on the washing quality?
A.
True.
Water is concidered as the predominant chemical used in the laundry process and effects washing quality and costs.
Traces of iron, chlorine, hardness and odorous materials affect fabric life, as well as appearance and acceptance.
