How To Clean A Watch Crystal? (Useful Tips)

Cleaning a watch crystal sounds like it should be a pretty easy task, but if you’ve never done it before, it can be a little bit daunting.

In this blog post, we’ll give you a few tips on how to clean your watch crystal so that it looks new again.

What you’ll need

Before cleaning a crystal, make sure you have all the necessary supplies.

You’ll need some sort of watch case opening tool (we recommend a “case knife” style opener, but many people prefer different types of tools.

You can find inexpensive ones online at eBay and Amazon), a soft cloth, and some form of cleaner.

Never use household cleaners such as Mr. Clean or Windex to clean your watch crystal.

These types of household cleaners contain chemicals that will actually damage the exterior acrylic or mineral crystal on your watch.

How to clean your watch crystal

In order to clean your watch crystal, you’re going to need to remove it from its band.

This applies to both metal and plastic bands.

Once you’ve done that, hold it under a light so that you can see where there are smudges or fingerprints on the outside of the crystal.

For most acrylic crystals, a toothbrush is sufficient.

For mineral crystals, you’ll want to use a soft brush with very gentle pressure.

This will loosen the dirt so that it’s easier to wipe or brush away.

Once you’ve loosened up all of the contaminants, take your watch cleaner and apply it directly onto the crystal using the cloth provided with it (or some other soft cloth).

Make sure you don’t let it soak into the case itself.

Wipe the crystal clean with your cloth, and polish to remove any excess cleaner still on the watch.

If you’re still noticing some gunk on your watch face after completing all of steps 1 & 2 above, it may be time for watch crystal cleaner.

You can find different types of crystal cleaners at your local jewelry store or even online.

To use a crystal cleaner, simply apply a few drops to a soft cloth and wipe down the area of your watch face along with the hands until they are completely clean.

How to put the crystal back on

After you’ve used any of the cleaning methods above, it’s important to make sure that your watch crystal is completely dry.

The best way to do this is to place the watch face down on a soft cloth and let air dry for an hour or two (or overnight if necessary).

Once it’s completely dry, you can reattach your watch to the band and wear it again.

If its crystal is severely scratched, you may want to consider getting a new one fitted.

This type of damage typically isn’t covered under warranties for watches because they can be difficult to replace due to their size or shape.

Tips and tricks

– Never use household cleaners to clean your watch crystal.

These contain chemicals that can actually damage the acrylic or mineral crystal on its case.

– Cleaning a watch crystal should be done just about once per year depending on how often you wear it.

If it’s worn daily, this will need to be done more frequently.

Just make sure you’re always cleaning it by hand with a soft cloth and not putting it underwater.

– If you find that your watch crystal is scratched up, you may need to have it replaced altogether.

Scratches on the acrylic or mineral crystals can cause glare when viewing sunlight, which can make seeing the time more difficult.

– Another thing to keep in mind when cleaning a crystal is the material it’s made from.

Acrylic crystals are great because they’re inexpensive and easy to replace, but they can scratch more easily than mineral crystals.

Mineral crystals are harder and much less likely to get scratched, but they tend to cost a little bit more and also require professional installation.

How do you remove scratches from a watch crystal?

Use toothpaste and a soft rag.

Put some on the rag and rub in gentle circles on the watch crystal.

This will buff out most of the scratches, but if it is too deep or too severe this won’t work.

In most cases, no.

If the crystal is only dust or dirt it will not affect your watch’s water resistance at all.
