Is Sparklean safe to use on all types of jewelry?

Yes. Sparklean's biodegradable, ammonia-free formula is safe for diamonds, pearls, opals, rubies, emeralds, sapphires, and all precious and semi-precious gemstones. It is also safe for gold, sterling silver, platinum, rhodium, brass, and copper. Because it contains no harsh chemicals, it will not damage delicate coatings, antique finishes, or costume jewelry.

How do I clean my diamond ring at home?

To clean a diamond ring at home, spray Sparklean Original Cleaning Spray directly onto the ring and let it sit for 10 to 15 seconds. For buildup under the stone or in prong settings, use the Sparkpen to reach tight crevices with its ultra-fine brush tip. Wipe with a soft lint-free cloth and buff dry. For a deeper clean, place the ring in the Sparklean Ultrasonic Cleaner with water for 3 to 5 minutes.

What is the difference between the Sparklean Spray, Sparkpen, and Polishing Cloth?

Each Sparklean product serves a different purpose. The Original Spray is an all-purpose cleaner for jewelry, eyeglasses, screens, and metal surfaces. The Sparkpen is a precision cleaning pen with an ultra-fine brush designed to reach under stones, into prong settings, and around intricate details. The Polishing Cloth is infused with real lemon oil to remove tarnish, surface scratches, and corrosion from metals and restore shine. For best results, use all three together: Sparkpen for detail work, Spray for overall cleaning, and Cloth for final polishing.

Can I use Sparklean to clean my eyeglasses and screens?

Yes. Sparklean Original Spray is formulated to safely clean eyeglasses, sunglasses, computer screens, phone screens, and camera lenses. It includes anti-fog technology that prevents fogging after cleaning and leaves no sticky residue. It is safe for all lens coatings including anti-reflective, blue-light, and polarized coatings.

Is Sparklean safe for a Rolex or luxury watch?

Yes. Sparklean products are ammonia-free, pH-balanced, and non-abrasive, making them safe for luxury watches including Rolex, Omega, Cartier, and other high-end timepieces. Use the SparkBrush with its ultra-fine bristles to clean around bezels, bracelet links, and case details without scratching. Follow with the Original Spray and a soft cloth to restore shine.

How does the Sparklean Ultrasonic Cleaner work?

The Sparklean Ultrasonic Cleaner uses high-frequency ultrasonic waves to create microscopic cavitation bubbles in water. These bubbles implode on contact with your jewelry, gently lifting dirt, oils, and grime from every surface and crevice without scrubbing. Simply fill the tank with water, place your jewelry inside, and run a 3 to 5 minute cycle. It is effective on rings, bracelets, necklaces, earrings, and small metal accessories.

Are Sparklean products biodegradable and ammonia-free?

Yes. All Sparklean products are biodegradable, ammonia-free, and pH-balanced. They are formulated by scientists to deliver professional-grade results without harsh chemicals. Sparklean products are made in the USA and are safe to use around children and pets.

Which Sparklean product should I buy first?

If you need an all-purpose cleaner for jewelry, glasses, and screens, the Original Spray is the best starting point. For the best value and a complete cleaning routine, the Ultimate Cleaning Kit Bundle includes the Spray, Sparkpen, Polishing Cloth, and SparkBrush at a discounted price.
