Excuse me, how to clean the CD so as not to make flowers?

Wipe with pure cotton or silk scarf. Of course, you can also wipe it with professional detergent. Actually, it's better to wipe it with velvet.

For specific methods, please refer to the cleaning method of telescope lens:

1) Stand the mirror upright and rinse it near the faucet for a second or two to let the water wash away the biggest granular dirt and leave some big water drops on the mirror. The next step will be useful.

(2) Put the mirror face up and gently drop a few drops of emulsion. Don't be afraid too much. The trick is to mix the detergent with the water left on the mirror to make it "slippery". In addition, be careful not to let water and detergent mix into the lens group.

(3) In fact, as long as you are careful, it is not easy to twist the lens group. Wipe the detergent that has dripped on the mirror slowly and gently with the index finger of your left or right hand. If some people have thick hands, they should use wet tissue instead of forefinger to clean the mirror.

(4) Stand the mirror upright, close to the faucet, and let the water wash away the cleaning agent. Please rest assured that the water will not enter the lens group after more than ten seconds. Ordinary optical lens groups, even if they are not nitrogen-filled or vacuum lens groups, will not let everyone down in this respect.

(5) Wipe off the remaining big water drops with a wet paper towel, but don't let the mirror dry completely. Leave some water, and the next step will be useful-it sounds like Zhajiang Noodles in instant noodles. Don't drain the soup completely after the noodles are soaked.

(6) Wipe the mirror with dry cotton paper, because there is still some moisture in the mirror, so the cotton paper will be a little wet when cleaning the mirror, making it the best tool to absorb tiny particles. You can use some force to wipe the residual stains, because after the fourth step is completed, the particles that are enough to scratch the mirror surface have been removed, so even if you use some force to wipe, it is not easy to push the sand particles to scratch the mirror surface.

If you don't use dry tissue paper, you can consider using tissue paper stained with medicinal alcohol. Some wedding photographers prefer to clean the lens like this. Because alcohol can not only help water evaporate quickly, but also dissolve dirt and prevent mildew. As for whether alcohol will damage the lens surface, I have no experience. But rubbing your glasses with alcohol is not a crime, so it's no harm to try. I heard that it was wiped with water, and the photographers quickly dissuaded me, saying that it would be moldy, and it would be better to use alcohol, knowing their love for medicinal alcohol.

(7) Wipe away the stains and suck up the water around the residual mirror. Sometimes you will find dirt around you, mostly the rust of lubricating oil or mirror hoop, so don't worry.

(8) If you feel it is not clean, you can lift it once from step 1, or stop here, and the lens can be covered and put into storage after half a day of air drying (I used to wash it for the third time because I used the wrong cleaning agent).
