Please tell me how to clean the helmet of the bicycle

I often hear people asking whether the helmet needs to be maintained and how to maintain it, and today we will briefly talk about the maintenance of the helmet.

The material of the helmet.

I believe everyone has already understood the material of the helmet, and the inside of the helmet is basically made of polypropylene (EPS). The helmet shell is made of materials such as polycarbonate (PC), ABS engineering plastic and PVC.

Polypropylene (EPS) is often referred to as foamed plastic, divided into a foam and secondary foaming, the EPS density of a foaming is relatively large, the hardness is high, generally used in high-grade helmets, the EPS density of the secondary foaming is small, the hardness is low, and the bubbles are small balls. Low-grade helmets also use this kind of secondary foaming EPS, which is one of the better products.

Polycarbonate (PC) is generally used in high-end helmets, because this material is lightweight, non-toxic and odorless, and has very good impact resistance, the windshield on the aircraft is also made of this material, ABS and PVC materials due to heavy weight, impact resistance is not as good as PC, so it is generally used in low-grade helmets.

Cleaning of helmets.

Generally, after the helmet is dirty, we can wipe it with a rag dipped in water, or clean it with a neutral detergent, but it must not be cleaned with organic solvents such as gasoline and banana water, because whether it is EPS or PC, they are all polymers and cannot be in contact with organic solvents, otherwise it will cause damage to the material.

Cranial locking device.

This device is generally made of plastic, and it is easy to be damaged if the force is too strong when adjusting the knob, especially after screwing to the end. If the sediment is accidentally stained on it, it must be cleaned off, otherwise the sediment will enter the device and damage the adjusting mechanism.

Adjust the angle. As shown in the figure on the right, the angle of the skull locking device is adjusted, and there are three angles in total, and the angle is adjusted by changing the position of the pin.

Pull out the pin, then move it to the desired bayonet, and then snap the pin in.

It can be adjusted to the following 3 states, of course, this is different according to the different head shape of each person.

Replacement of the liner.

The padding is thick and thin and can be adjusted according to your head shape, and each model of helmet has its own specific padding .

It is best to dry it in the sun, or blow dry it with a hair dryer. Then use a brush to clean out the debris inside, and finally wash and scrub normally, you can use some disinfectant water, after all, it is a close thing, and then it is OK to dry it after cleaning.

Dip a toothbrush with toothpaste.

Removes stains quickly.

When the helmet is used for a long time, dirt often accumulates inside it and produces odors. In this case, it should be cleaned. It is better to use a neutral cleanser, and it is better to use a shampoo.

To avoid odors left by detergents, the amount of detergents used should be controlled. When brushing the inside of the helmet, do not use too much force. Otherwise, the cushioning material will be deformed and its cushioning function will be lost.

After cleaning, wipe off the water with a towel or paper towel and let it air dry in a ventilated place, and do not use equipment such as a hair dryer.

The inner tank is dismantled and washed by hand. Wipe the shell with a soft cloth with water, and then dry it with a dry cloth. A good helmet does not need to be waxed, the original layer of varnish is much harder than wax, and it is much brighter, and it is useless to wax and seal the glaze.

Never wash or wipe the helmet passing by - I have always bought a helmet for 100 yuan... The new helmet has just been bought.,It's estimated that it won't be disassembled and washed until next year.。。

How do you wash a dirty helmet? Lao Wang teaches you three methods, the gospel of the lazy.

Inner Dan gold spinning bubble, outside soft cloth rubbing.

Disassemble the lining and clean it with a professional foam cleaner.

1. The cleaning method for dirty inside the helmet is to directly put the laundry detergent.

Soak it first, pour it into the helmet and soak it for a while, then clean it with water a few times, take it out and blow dry.

2. The surface of the helmet is often stained with dust and oil, so wiping the surface is a regular job. When the helmet is stained, first use a damp cloth to clean the stain, and then use the water used to wipe the car.

Or polish wax rubbing to make the helmet clean and shiny.

1.After a simple rinse of fine sand particles on the outside of the helmet and on the lenses, place the helmet on a towel-covered tabletop and spray the spray completely onto the helmet liner until it completely covers the lining.

2.The outside of the helmet and the lenses (if the inside is not dirty, if the inside of the lens is dirty, it is recommended to remove it and wash it separately) is also completely sprayed and covered.

3.Leave on for 5-10 minutes for the detergent to penetrate and react.

4.After 10 minutes, the cleansing foam begins to evaporate until a faint fragrance is left behind, which can be wiped with a cloth.

5.For the insect corpses on the mask and the stains on the helmet, the dirt can be quickly removed with a cloth, and finally wiped with a flannel cloth to achieve a clean and bright effect.

A bottle of Motorex helmet cleaner can be used about 5-8 times, about 10-20 yuan a time. A pack of cigarettes can make the smelly helmet regain its fresh taste.

Motorex helmet cleaners are all natural formulas, mild in physical properties, and do not harm the human body**, if individual riders do not like this taste, you can consider using Muc-off's lemon-flavored helmet cleaner].

First, wipe off the dirt with a damp paper towel dipped in some mild dish soap, and then remove the corners of the lens to clean. After taking out the interior, soak it in a solution with dish soap for a few hours, then gently rub it with your hands, clean it and let it dry in the sun for half an hour, which can play a role in disinfection and sterilization.

The cleaning method of the shell is relatively simple, you can use a wet paper towel dipped in some neutral dish soap to wipe off the dirt, or replace it with a dry towel, carefully wipe the dirt on it several times, and then remove the corners of the lens for cleaning, and then install it according to the original method.

Then disassemble the interior, first soak it in a solution with dish soap for a few hours, let it play the role of disinfection and sterilization, and the dirtiest part that touches ** can be dipped in some laundry detergent and rubbed carefully, but not brushed with a brush, otherwise it is easy to pill.

After rubbing it clean, rinse it in clean water for a few more times, then wring out the water in the memory, and put it in the sun to dry for half an hour, which can play a role in disinfection and sterilization, and it is more comfortable to wear.

1. The helmet lining is recommended to be cleaned at least once a month, sweating a lot, and having multiple sets of linings or multiple helmets can also be washed once a week, depending on your personal preferences.

2. The lining is now generally divided into detachable lining and fixed lining; The detachable lining is more convenient, and those that need to be machine washed can be put into a laundry net bag after disassembly and machine washed, and the other is the traditional hand wash; Hand washing is recommended here, so that the lining is not easy to deform.

3. The fixed lining can only be wiped with the aqueous solution of the neutral cleaning agent, if the lining is too dirty, you can dilute the neutral cleaning agent with water or warm water, fully soak the cleaning cloth, and wipe the lining by patting; If there is a smell of sweat or other odors, you can use a sterilizing cleaning agent, etc.

4. After cleaning the lining, please dry it in a cool place, and then use it after it is thoroughly dried, if there is residual moisture, it may cause peculiar smell.
