Food-Grade Effervescent Descaling Tablets for Kettle Tea Stains

**EN:** Keep teaware sparkling clean with these food-grade active oxygen effervescent descaling tablets. Specially formulated to tackle stubborn tea stains, limescale buildup, and mineral deposits that commonly affect kettles, water cups, teapots, and tea utensils in regions with hard water. Each tablet dissolves quickly in warm water, releasing powerful oxygen bubbles that penetrate deep into crevices, lifting away grime without harsh scrubbing or chemical residues. Safe for use on stainless steel, glass, ceramic, and porcelain surfaces. The food-grade formula ensures no harmful substances contaminate drinking water, making it ideal for households, offices, tea houses, and hospitality businesses. Perfect for the high tea-consumption markets of Central Asia, Russia, and South Africa, where hard-water limescale is a daily challenge. Simply drop one tablet into the vessel, add warm water, wait 15–30 minutes, then rinse thoroughly. The compact tablet format saves shelf space, lowers shipping weight, and supports higher margins for resellers. A high-turnover consumable with strong repeat-purchase potential and proven demand across tea-loving regions. **中文:** 活氧泡腾除垢片，食品级配方安全无残留。强力分解茶垢、水垢及顽固茶渍，适用于水壶、水杯、茶壶、茶具等。不伤器具表面，深层清洁无刺激。投放一片即用，操作简便，适合家庭、办公、茶馆、酒店批量采购。
