Can I use alcohol to wipe my resin spectacle lenses to disinfect them?

Can the lenses be wiped with medical alcohol?

No

Although the price of digital cameras is declining day by day, especially in recent years, there are some high-end consumer machines There are many models available for high diving, but for every DC owner, the DC that they have saved up their hard-earned savings for is cherished, especially the lens, which is the most critical component of DC, and there is no room for a trace of dust on it. How to take good care of the lens? There are many DC enthusiasts, especially junior photographers, who don’t know much about this. We summarize it into the five key points of “blowing, scrubbing, washing, protecting and drying”:

1. Blow< /p>

It is best to blow away the dust on the lens instead of wiping it. Because the coating on the surface of many lenses is very delicate, small dust particles will be scattered on the surface of the lens. If we directly wipe it with lens paper, the dust will act as sand grains on the sandpaper between the paper and the lens film surface, which will easily Damage to the delicate film surface, and for the plastic lenses of low-end consumer machines, the situation is even worse. Therefore, the correct approach is to use a special air blower, which is also available in medical equipment stores, and its scientific name is an ear cleaning ball; or you can buy it at a photographic equipment store. There are many types, but there are some plastic blowers in the photographic equipment store, and the blowing force is not very strong. Large, rubber material is the best, just hold it in the palm of your hand and pinch and blow towards the camera.

2. Wiping

Blow away the dust before wiping. Generally, those with watermarks and marks should be cleaned as soon as possible. Traces and stains such as saliva or acidic and alkaline rainwater will slightly corrode the membrane, and may damage the membrane surface over time. The way to clean it is to take a breath at the lens and use lens paper to wipe the surface of the lens in a clockwise or counterclockwise direction. Be sure not to wipe back and forth. The key points of wiping are: light in, slightly heavy wipe, and light again as a process. And after wiping, you must change the paper area before wiping. Suede is a good lens wipe, but the quality of artificial suede varies, so don’t use it properly. If any part of the natural suede becomes hard, be sure not to use it again, as it can easily scratch the lens. Current consumer DC lenses are very small and cannot be wiped completely with lens paper or suede. It is recommended to use a special lens pen with a brush on one end to brush off larger dust; The suede head has a small area, but the effect is good. It can be used to wipe off marks and stains on small lenses. The marks and stains on large lenses do not require a large area of ????wiping. The only disadvantage is the price. A bit expensive, the cheap one is about 50 yuan, and the good quality one is about 200 yuan.

3. Washing

If the stain on the lens is large, or the traces remain for a long time, or are sticky, and simple wiping cannot solve the problem, then simple cleaning of the lens is required. of cleaning. The cleaning method is very simple. Find a medical cotton swab, that is, an absorbent cotton ball. There must be a thicker cotton ball at one end of the wooden swab to prevent the cotton ball from being too thin and the wooden swab scratching the surface of the lens. Use a cotton ball dipped in a little pure water and squeeze out the water, that is, in a moist state, scrub the stained area several times in one direction. After the stain is removed, blow dry with an air blower, and then clean it with lens paper according to step 2. If it can be cleaned with just water, don't use alcohol or other cleaning fluids.

4. Protection

The above three methods are all passive ways to protect the lens, and the most effective protection for the lens is to install a UV mirror for the DC, because a UV mirror only requires a few For ten yuan, a relatively closed environment is formed between the UV mirror and the lens surface, which can effectively isolate dust. You can also use the above method to clean the UV mirror. Even if it is damaged, you don’t have to worry.

5. Dryness

Whether it is the DC lens or the electronic components of the camera body, they must reject humid environments. Therefore, after shooting in rainy days or after wet cleaning of the lens, it is recommended to dry it and place it in a drying box. In fact, we make our own drying box. Go to the supermarket to buy a plastic storage box with better sealing and moderate size, collect a little desiccant (found in many electronic equipment packaging, or some small food packaging) and put it in the box. .
