Jewellery Care & Cleaning Tips
- Jewellery needs regular cleaning.
- Customers can clean their jewellery at home to keep them look at their best or bring them in at a jewellery store for cleaning.
- Jewellery also needs periodical check and cleaning by a jeweller every 6 months (recommended).
- Customers can use a jewellery box with compartments at home so items don’t get scratched, they have to be stored separately.
- Some commercial jewellery cleaning products are available in the market (ammonia-based) and can be used to clean precious metals, diamonds, & most color stones except porous gems like pearls, emeralds, etc..
- Chlorine bleach, a common household liquid, can pit gold alloy exactly the same way as chlorinated water used in the pools. So customers who swim a lot should be aware of that. If an alloy becomes pitted, it weakens, making gemstone loss possible.
- The best and safest tools for cleaning most jewellery are a soft toothbrush, warm soapy water, a pulsed-water dental hygiene machine, and a soft lint-free cloth.
- Customers can buy small ultrasonic cleaning machines but keep in mind to be educated on their proper use and the fact that some colored stones should never go into an ultrasonic cleaner. Also be reminded that some jewellery which have fracture-filled diamonds and require prolonged sessions in the ultrasonic cleaner might damage the filling.
- Dirt can have a negative optical effect on a diamond’s appearance (clarity & color).
- Diamonds pick up oil from hands & dust and dirt collect in the oil, that’s why diamonds get dirty and need cleaning.
- It’s professional to handle loose diamonds with tweezers and to hold mounted stones by their setting.
- Most jewellery stores have an ultrasonic cleaner and a steam cleaner.
- A machine that cleans jewellery with high-frequency sound waves in a liquid solution. This removes built up dirt and grease from jewellery. It can also shake stones loose from their mountings. Ultrasonic cleaners are safe for most diamonds but might harm the filling in some fracture-filled stones.
- Customers should be aware of the stones that can not be cleaned in ultrasonic cleaners like Emerald, Lapis, Turquoise, Opal, Pearls,…etc.
- A machine that cleans jewellery with pressure steam. It quickly removes dirt and build-up. Pressure, however, can force dirt into cracks in the stone’s surface or loosen stones from their mountings. A stone can fly into a wall or the sink by pressure, steam cleaning can also damage treated stones like ultrasonic cleaning.
Note: If you’re unsure about a stone, just don’t clean it in these machines.
Always remember that:
- he safest jewellery cleaning is warm water, mild soap, & soft toothbrush with a lint-free piece of cloth to wipe out.
- Extra caution should be taken when cleaning jewellery over a sink, always make sure the sink’s drain is plugged to avoid loss of stones that come loose while cleaning.
Watch Care Tips
Watches are precision instruments so taking proper care of watches will not only keep customers stay in time, it will also ensure the watch to last for generations to come.
Watches should be serviced by a jeweler or certified watch repair specialist according to the manufacturer’s service guidelines.
TYPES OF WATCHES
A- MECHANICAL (2 types)
- HAND-WINDING (MANUAL)
- BATTERY OPERATED
Basic Facts about Mechanical vs. Quartz Movements in watches
|Power Sources|| Timekeeping Accuracy|| Number of components|| Dangers|| Lifespan|| Service|
| Metal Spring|| 1 minute per week (approximately)||* 100-500|
* About 70 friction points
* Assembled by hand
* Magnetic fields
* Extreme temperatures
| Theoretically unlimited|| Every 5 years for overhaul service|
| Chemical reaction in the battery|| 1 minute per year (approximately)||* 20-50|
* About 20 friction points
* Assembled by machinery
|* Battery leakage|
* Extreme temperatures
| 20-30 Years|| Every 2 years for battery replacement|
- Replace battery before it runs out.
- Don’t leave dead batteries inside the watch, leak may cause damage to your watch movement.
- Check water-resistance of your watch, don’t wear it at shower or in the pool unless it’s water-resistant.
- If water-resistant and in metal or rubber band, you can clean it with a mixture of warm water and either mild soap or dish detergent & then dry it with a soft cloth.
- If water-resistant and with leather strap, you can clean only the watchcase in the same way with caution so to avoid damage to the leather strap.
- 10 Meters- 33 Feet- 1 ATM:
Watches are protected against accidental exposure to water splashes, perspiration or accidental immersion in water. They should not be exposed to any water pressure and never worn for swimming or bathing.
- 30 Meters- 100 Feet- 3 ATM:
Watches can withstand splashes or brief immersion in water, or getting caught in the rain but are not sufficiently resistant for swimming or bathing.
- 50 Meters- 165 Feet- 5 ATM
Watches are wearable around household sinks, while playing sports and swimming in shallow water but not while bathing, snorkeling, or scuba diving.
- 100 Meters- 330 Feet- 10 ATM:
Watches are wearable around household sinks, while playing sports and while swimming, poolside diving or snorkeling but not while scuba diving.
- 150 Meters- 500 Feet- 15 ATM:
Watches are wearable around household sinks, while playing sports and while swimming or poolside diving. They are also suitable for snorkeling and scuba diving.
Manual/Hand-Winding (MW) & Automatic/Self-Winding (Auto)
- Don’t store the watch for long time, wind regularly to keep lubricant flowing (both).
- Try to wear your watch everyday and consider buying winding boxes (winders) if you own several mechanical watches (Auto).
- Wind daily to guarantee top performance & peak accuracy (MW).
- Wind consistently, at the same time everyday (recommended) to ensure the highest quality performance (MW).
- Don’t wind the watch while on your wrist to avoid long-term damage to the winding stem, always take it off and wind it before you put it back on your wrist or just wind it before your wear it (MW), the same for automatic watches if you wind them manually.
- Avoid water if your watch is not water-resistant (both).
- Pay attention to specific instructions by the manufacturer about how much pressure your watch can handle even if it is water-resistant (both).
- If you wear your water-resistant watch in the pool, while the water may not harm your watch, chlorine can still be damaging (both).
- Don’t pull/open the crown of your watch or operate any of the buttons while under water or when the watch is wet even if your watch is a diver watch or water-resistant. This may cause the water to flood the inside of your watch (both).
- Don’t shower with your watch, shampoo & soap can be harmful for the gears of the movement (both).
- Seals to resist water can crack over time, so just be careful and remember to schedule your regular service (both).
- Stay clear of strong magnetic fields which may cause erratic gear behavior. This may also stop the watch entirely. Check if your watch has magnetic resistance, most modern watches do (both).
- Don’t wear the watch in extreme temperatures as this may cause damage to the whole unit specially moving between excessive hot and cold temperatures (both).
- Don’t keep your watch in extreme heat as this may also result in and cause friction on the gears (both).
- Avoid harmful objects that may scratch your watch, as well as dirt and chemicals that can cause damage, rust, corrosion or wear slowly over time.
- Remember that scratch-resistant doesn’t necessarily mean scratch-proof (both).
- Schedule service for your watch once every 3-5 years (Both), while every 2 years for pocket watches (MW), (check manufacturer’s manual).
- Take your watch in for periodical clean/polish by certified watch service centre of authorized dealers to prevent buildups and dirt(both).
Watch Metal Bracelets/Leather Straps/Rubber Bands
Stainless Steel Metal Bracelets:
To prevent corrosion that appears like pitted metal, rust, or tarnish on metal bracelets, avoid
- Salt water from ocean or sea (even air near ocean affects if you live near ocean).
- Sprays and lotions (chemicals).
- Sweat & perspiration.
- Body oils.
Stainless steel watches don’t react with perspiration and they’re the toughest to corrode while platinum, gold, & titanium watches tend to be more inert and less likely to react with sweat to cause corrosion. If water-resistant enough, you can clean your watchcase & metal bracelet with a soft brush & warm soapy water, then thoroughly rinse it off with clear water and dry it completely or wipe it with a clean soft cloth.
- Avoid direct exposure to sunlight or hot temperature that may cause color change or damage to the strap.
- Heavy perspiration if not removed from a leather strap can wash out the natural oils and cause leather to become dry & deteriorate.
- Any moisture should be blotted with a soft cloth or paper towel and the strap allowed to dry naturally.
- Salt residue and soil can be removed from the leather by cleaning with a dampened soft cloth and mild soap or saddle soap.
- Occasionally, the inside surface of the strap should be cleaned by using a soft cloth dampened with alcohol.
- The strap should be always worn a little loose (one finger space between wrist & strap) to allow air to circulate thus allowing any moisture to evaporate.
- Replace the strap before it gets smelly or too soiled.
- If the watch is water-resistant and used in shower, chlorinated or salt water, dry the strap carefully and immediately with a clean soft cloth.
- Rubber band should be washed frequently with mild soap and warm water using a soft brush.
- If the watch is water-resistant and used in shower, chlorinated or salt water, dry the rubber band carefully and immediately with a clean soft cloth.
- Solvents, oils, perspiration, tanning lotions, and salt can cause rubber to deteriorate if not removed immediately.
- Pay careful attention when wearing special colors of rubber bands like white, grey, sky blue,..etc to avoid hard stains.
