1. Types and uses of cleaners
There are more and more brands of cleaners nowadays, but there are no more than three main types, namely acid cleaners, neutral cleaners and alkaline cleaners.
(1) Acidic Purifier (0 <7)
Acid cleaners are mainly used for cleaning toilets, since acidity has a certain bactericidal and deodorizing function; acidic acid neutralizes stubborn stains such as urine lye and cement, so some strongly acidic cleaners can be used for routine sanitization; Acidic cleaners are usually liquid, and some are powdered. Since acid is corrosive, special attention should be paid to amount and method of use. Do not use acidic cleaners on carpets, stone, wood and metal utensils.
There are many types of acid cleaners, and their functions are also slightly different. Pay special attention to instructions before use.
(2) Neutral detergent (PH=7)
Chemicals with PH=7 are called neutral agents, while commercial detergents with 6≤PH<8 are called neutral detergents The function of cleaning and protecting objects to be cleaned is widely used in daily cleaning and sanitation. Neutral detergents come in liquid, powder and paste forms. The disadvantage is impossibility or difficulty of removing serious contaminants. Now they are widely used in hotels. Multi-purpose cleaners fall into this category.
(3) Alkaline cleaner (0 <14)
Alkaline cleaners do a good job of removing greasy and acidic contaminants, but they must be diluted before use and rinsed with clean water after use, otherwise surface of object being cleaned will be damaged after a long time. Alkaline cleaners are available as liquid, cream, powder, and paste.
Alkaline and neutral detergents contain not only soda ash. To enhance disinfecting effect and improve cleaning effect, composition of detergent often contains a large number of other compounds, among which most commonly used and largest number are surfactants.
Surfactant is a substance that can effectively reduce surface tension of solvent and reduce strength of bond between dirt and object being cleaned. Its content and quality form a variety of cleaning products with different disinfecting effects. .
In addition to surfactants, cleaning products also contain other compounds such as bleaches, foam stabilizers, fragrances, etc.
Second, types and uses of cleaning products commonly used inhotels
When carrying out scheduled sanitation work, using right cleaning agent not only saves time and effort, improves work efficiency, but also helps to extend life of object being cleaned. but cleaning agent Both cleaning agent and object being cleaned have a relatively complex chemical composition and action, so if cleaning agent is not used correctly, it will not only not give expected effect, but also damage object being cleaned. Therefore, it is very important for hotel to choose right cleaning agent.
The following types of cleaning products are commonly used in hotels today:
(1) Acidic Cleaner
1. Hydrochloric acid (PH=1) Mainly used to remove dirt left during construction of infrastructure, such as cement, lime and other stains, effect is obvious.
2. Sodium sulfate (PH=5) can neutralize reaction with urine with alkali and can be used to clean toilet drums, but cannot be used universally and should be in small quantities.
3. Oxalic acid (PH=2) The use is same as that of hydrochloric acid and sodium sulfate, but cleansing effect is stronger than that of sodium sulfate, so special care should be taken when using it.
The above three acidic cleaners can be used in small quantities to remove stubborn dirt or routine sanitation. However, it must be diluted before use, and a concentrated solution cannot be poured directly onto surface of object to be cleaned.
4.Toilet bowl cleaner (1≤PH≤5) Toilet bowl cleaner is acidic, but contains synthetic antacids to increase safety margin.It has a special washing, deodorizing and bactericidal effect.It is used to clean toilet barrels, men's toilets , washbasins and other appliances. When used, it must first be diluted according to instructions and must be poured into clean water in toilets and urinals, not directly onto surface of object being cleaned.
5. Disinfectant (5 <9) Mostly acidic, it can be used as a bathroom disinfectant and can also be used to disinfect cups, but must be rinsed with water. Disinfectant "August 4" is better)
(2) Neutral detergent
1. Multipurpose cleaner (6≤PH≤8)
2. Carpet CleanerThis is a neutral detergent specially used for washing carpets. Due to difference in amount of foam stabilizer, it can be divided into two forms: high foaming and low foaming. , Low foam is usually used for wet carpet cleaning, high foam is used for dry carpet cleaning, if low foam is used for carpet washing, it should be diluted with warm water, and effect will be disinfectedania is better.
(3) Alkaline cleaner
1. Glass cleaner (7≤PH≤10) There are two types of glass cleaner: in barrels and in high pressure aerosol cans. function - stain removal; when using, it must be installed in a watering can and sprayed on dirty spots, and then wiped with a dry cloth, it will be bright as new. The latter contains volatile solvents, fragrances, etc., which can remove oily dirt and leave fragrance after use. And it will leave a transparent protective film on glass surface, which is more convenient for future cleaning work, and has a good effect of saving time and effort, but price is higher.
2. Furniture Wax (8≤PH≤9) In daily cleaning of room, waiter simply uses a damp cloth to remove dust from furniture and oil stains from surface of furniture. can not be removed. Diluted multi-purpose cleaners can be used to thoroughly remove scale, but long-term use will cause furniture surface to lose its luster. Furniture wax should also be used regularly. There are several forms of furniture wax, such as emulsion, spray and paste. Function, it can not only remove stains of animal and vegetable oil from surface of furniture, but also form a transparent protective film, which has functions of antistatic and mold protection. The method of application is to pour an appropriate amount of furniture wax on a dry rag or furniture surface, wipe once, its function is to clean furniture, and then wipe again in same way after 15 minutes, this is glazing time.
3. Waxing water (10 <14) Used for marble and wood floors that need to be re-waxed. Waxing water has strong alkalinity and can dissolve old wax and dirt to achieve wax removal effect. When using, it should be borne in mind that primer must be washed several times before re-applying wax.
(4) Glazing agent
1. Copper wiping waterCopper wiping water is in form of a paste. The basic principle is to oxidize copper rust on copper surface to achieve purpose of cleaning shiny copper products. This should note that it can only be used for pure copper products, can not use for copper-plated products, otherwise coating will be oxidized.
2. Metal Polish Contains mild abrasives, fatty acids, solvents and water. Mainly used in copper products and metal products, such as faucets, roll holders, shower curtain rods, towel racks, lock handles, handrails, etc., which can play role of rust removal, decontamination and glazing. The use of metal structures.
3. Floor wax Floor wax is divided into sealing wax and surface wax. Sealing wax is mainly used forThe top layer of base wax, which contains fillers, which can block pores on ground surface and play role of smoothness. The top wax is mainly used for polishing and polishing, improving smoothness and reflectivity. intensity of earth, making earth more beautiful.
Wax can be both water-based and oil-based. Water-based wax is commonly used on marble floors and its main component is a polymer that forms a thin protective film when dry, oil-based wax is mainly composed of mineral paraffin, which is often used on wooden floors. hard, pasty. There are three types of floor wax: solid and liquid, which are commonly used, pasty and liquid.
Solvents are volatile liquids and are mainly used to remove stains from objects to be cleaned that are afraid of water.
1. Carpet stain removerSpecially used to remove special stains from carpets, especially wool carpets. There are many types of carpet stain removers, such as juice stain removers and stain removers. Dirty stains and gum removal. However, if there are dirty spots on carpet, they should be wiped out in time, otherwise stain removal effect will not be obvious.
2. Dust Remover (Electrostatic Water) Used to soak vacuum cleaner, and daily cleaning and maintenance of water-free floors such as marble and wood floors, to clean and maintain floor effect.
3. InsecticidesThis refers to aerosol cans of highly effective insecticides (such as Bipu, Radar, etc.) used by waiters. Reptiles and flying insects such as mosquitoes, flies, and cockroaches. But for rats, you should buy a special rodenticide or contact a professional company with it.
4. Alcohol Used to clean items such as phone disinfection.
5. Air FreshenersThere are many types of air fresheners and quality of products varies greatly. The easiest way to distinguish quality is to look at length of fragrance. The air freshener has functions of sterilization, deodorization and aromatization of air.
3. Precautions when using hotel cleaners
In order to use cleaning products efficiently, maximize their effectiveness, reduce waste, and improve safety of cleaning and maintenance work, cleaning products commonly used in hotels must be strictly managed and controlled. When using, pay attention to following points:
(1) General cleaners are concentrated solutions, which must be diluted strictly according to instructions before use, and proportion of water is moderate. If endthe consumption is high, detergent will not only be wasted, but also damage object being cleaned; if concentration is too low, cleaning effect will not be achieved, and it will not meet hygiene requirements of a three-star hotel, which will affect hotel's service quality.
(2) Do not use powdered cleaning agents. Since detergent powder has a frictional effect on surface of object being cleaned, especially on surface of sanitary ware, it damages surface of object. At same time, powdered detergents tend to precipitate during dissolution process, and it is often difficult to achieve best cleaning effect.
(3) The appropriate cleaning agent should be selected according to different chemical properties, use and hygiene requirements of objects to be cleaned, so as to meet cleaning and maintenance requirements of hotel.
(4) The cleaning agent should be tested on a small area before its first use, and only those that have a good effect can be advertised and used on a large area.
(5) Distribution and control of cleaning agents should be carried out properly in order to reduce unnecessary waste.
(6) High-pressure canister cleaners, volatile solvent cleaners, and strong acids and strong acid cleaners must observe safety precautions when using them. The former are highly flammable and explosive, while latter easily damage human skin. The waiter must master correct way to use in daily work, use appropriate protective equipment, and prohibit smoking in work area.
(7) Excessive use of any cleaning agent at one time will have varying degrees of side effects or even damage to object being cleaned. This method is time consuming, laborious, inefficient, and don't expect a good cleaner to be very effective on any old grime.
(8) The hotel must select the appropriate cleaning agent according to its financial situation.
