This process reduces surface tension, allowing dirt, tarnish, and oxidation to be lifted away from jewelry and metal pieces via gentle bubbles with no abrasion, no heat, and no metal loss. Stones are cleaned safely without the potentially damaging friction or heat that other cleaners can produce. Rinsing and drying after immersion naturally enhances the renewed luster.\u003c\/p\u003e\u003ch3\u003eFeatures\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eConcentrated formula—recommended dilution of 1 part concentrate to 6 parts water\u003c\/li\u003e\n\u003cli\u003eOdorless and environmentally safe\u003c\/li\u003e\n\u003cli\u003eContains no caustic chemicals or ammonia\u003c\/li\u003e\n\u003cli\u003eFast-acting degreaser that also removes oxidation\u003c\/li\u003e\n\u003cli\u003eBrightens metal to a like-new finish\u003c\/li\u003e\n\u003cli\u003eFunctions as the electrolyte in ionic cleaning systems\u003c\/li\u003e\n\u003cli\u003eCan be reused multiple times before replacement is needed\u003c\/li\u003e\n\u003cli\u003eEffective as a standalone tarnish-removing dip for costume jewelry\u003c\/li\u003e\n\u003cli\u003eCompatible with SpeedBrite ionic cleaners for enhanced speed and effectiveness\u003c\/li\u003e\n\u003cli\u003eNo abrasion, heat, or friction—safe for stones and metal\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003ctable\u003e\n\u003ctr\u003e\n\u003cth\u003eFormula\u003c\/th\u003e\n\u003ctd\u003eConcentrated ionic cleaning solution\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eDilution Ratio\u003c\/th\u003e\n\u003ctd\u003e1 part concentrate to 6 parts water\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eOdor\u003c\/th\u003e\n\u003ctd\u003eOdorless\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eCaustic Chemicals\u003c\/th\u003e\n\u003ctd\u003eNone\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eAmmonia\u003c\/th\u003e\n\u003ctd\u003eNone\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eReusable\u003c\/th\u003e\n\u003ctd\u003eYes—use repeatedly before replacing\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\u003ch3\u003eAvailable Options\u003c\/h3\u003e\u003ctable\u003e\n\u003ctr\u003e\n\u003cth\u003ePart #\u003c\/th\u003e\n\u003cth\u003eSize\u003c\/th\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e123.661A\u003c\/td\u003e\n\u003ctd\u003e1 Quart (32 oz)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e123.662A\u003c\/td\u003e\n\u003ctd\u003e1 Gallon\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e","brand":"Speed Brite","offers":[{"title":"1 Quart (32 oz)","offer_id":47551727632598,"sku":"123.661A","price":35.0,"currency_code":"USD","in_stock":true},{"title":"1 Gallon","offer_id":47551727665366,"sku":"123.662A","price":65.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0609\/9832\/0342\/files\/gem-sparkle-ionic-tarnish-removing-concentrated-solution-otto-frei.jpg?v=1719955422"},{"product_id":"small-parts-cleaning-basket-spring-type-ultrasonic","title":"Small Parts Cleaning Baskets Spring Type Small or Large","description":"\u003cp\u003eSpring-closed cleaning baskets designed to securely hold small parts during ultrasonic cleaning.
