Can I use a cotton swab as a match?
No. Use cardboard or wooden swab holders only, and acetone will dissolve the plastic holders of the swab.
Before cleaning the lens using acetone, clean any sneezing or breathing stains using distilled water and let it dry.
You do not have to follow the following steps unless the lens is still not cleaned.
Take a new cotton swab and soak it in pure and distilled vinegar. Using a little pressure, clean both sides of the lens.
Now soak another cotton swab in acetone and use it to clean off vinegar residues. For the liquid to evaporate, remember to use slight pressures.
What can I use if I don’t have acetone?
You can use some methyl or ethyl alcohol instead of acetone. You might use it, but alcohol evaporates slowly compared to acetone and might leave residues on the lens. Therefore, it is better to use acetone.
If the lens has scratches or burns, you cannot clean it properly and have to replace it.
When using acetone, be careful as it is highly flammable. Please avoid contact with your skin and keep it out of children’s reach. Before using acetone, see if there is any restriction in the manual.
Here are a few points that you should remember about different laser optics-
For metal optics, metal polishers can be used for cleaning. Use the latex glove to remove stubborn marks and follow steps 1 and 2.
Do not follow any of the steps above for mirrors coated with soft gold, as the mirrors have delicate surfaces. A non-contact method is preferred, like rinsing with acetone and spraying dry nitrogen.
For mirrors coated with solid gold, follow steps 1 through 4. These mirrors have harsh surfaces; therefore, you can use acetone. But the mirrors cannot come in contact with water, as the coatings may peel off if it comes in contact with water.
For Zinc Selenide (ZnSe) focusing lenses, you blow off any dirt from the surface of the lens using compressed air. Then follow steps 1 and 2.
