Diamonds are the hardest of gemstones ranking a 10 out of 10 on the Mohs scale. Platinum is one of the most durable and hard-wearing precious metals used in jewelery design. While used together these two materials are scratch, nick and wear resistant. However, like any other jewelry they may collect a dulling coat of build-up from lotions, hair products and skin oils with frequent or daily wear. Effective options for cleaning away this build-up can be created easily and safely at home with just few common household items.
Dish Liquid Solution
Household dish liquid is safe and effective at cleaning your diamond and platinum jewelry. Whip up a cleaning solution of one teaspoon dish liquid diluted in 10 parts warm water. Swirl to combine and soak your jewelry items for at least 10 minutes or up to an hour in the solution gently scrubbing with them with a soft toothbrush if needed. Rinse well in warm running water -- with the drain stopper closed for safety -- and lay the pieces onto a clean towel for air drying before buffing to a shine with a soft cloth.
Most professional jewelry -cleaning solutions are based on diluted ammonia formulations with colorants and scents added. Ammonia has long been the standard solution for cleaning diamonds. Mix a solution of one part of plain clear household ammonia to one part cold water in an unused glass bowl or old jar and soak your jewelry half an hour or longer. If there is build-up in the chasing of the band or setting of the stone, scrub gently with a soft child-sized toothbrush dipped in the solution to dislodge it. Rinsing is not needed unless the residual scent of ammonia bothers you. If so, simply rinse the items in cold water and air dry on a clean dry towel for a haze-free finish.
Pure, unflavored vodka serves as an ideal jewelry cleaner for diamonds set in platinum and leaves them with a bright, sparkly and spot-free finish. Purchase an inexpensive or store-label brand of plain clear vodka. Pour 1/4 to 1/2 cup or more of undiluted vodka, covering the jewelry item, into a glass cup or bowl. Place the item gently into the vodka and allow to soak for between 10 minutes and one hour depending of the degree of soil and build-up. Lift the item out of the vodka after soaking and scrub with a soft child's toothbrush under and around the stone and setting to lift any remaining debris. Place the item back into the vodka to rinse by gently swirling or agitating the items. Remove the jewelry and air dry on a clean, dry towel. Rinsing with water is not required as vodka is a fairly impurity free liquid with no sweeteners or dyes.
