CleenU product solution
Tea & Coffee Stain Remover
Active-oxygen soak · Fades tea rings · Private label
Brown tea and coffee rings that dish soap won't touch? Dissolve one scoop per 17 oz of 140°F+ water, soak 15–30 minutes, brush lightly, and rinse, and cups go back to their original color. Factory-direct private label.
- Tea stains are polyphenols and coffee pigment bound to hard-water minerals, layering up on the cup wall; dish soap removes surface oil but not that brown layer. This powder releases active oxygen in hot water to fade the pigment, while washing soda and sodium citrate loosen the mineral layer, so a soak and a brush bring the cup back.
- Ceramic, glass, stainless tumblers, teapots, strainers, and carafes all soak well. Aluminum darkens from the alkali, clay teapots are often seasoned on purpose and porous enough to hold residue, and hand-painted or gilded china should be avoided. Rinse thoroughly before drinking from it.

How it works
How tea stains fade
Tea stains are oxidized, polymerized polyphenols, tannins, and coffee pigment bound to calcium and magnesium. Percarbonate dissolves into hydrogen peroxide in hot water, releasing active oxygen that breaks the color-producing structure of the pigment; washing soda raises alkalinity and sodium citrate chelates minerals so the deposit loosens, and a brush and rinse remove it.
- Dissolve one scoop in hot water
- Releases active oxygen
- Fades pigment
- Chelates minerals
- Brush and rinse

Where Tea & Coffee Stain Remover stands out
Tea stains are pigment plus scale
Tea stains are polyphenols and coffee pigment bound to hard-water minerals, layering up on the cup wall; dish soap removes surface oil but not that brown layer. This powder releases active oxygen in hot water to fade the pigment, while washing soda and sodium citrate loosen the mineral layer, so a soak and a brush bring the cup back.
What to watch out for

Frequently asked questions (FAQ)
Find practical answers about Tea & Coffee Stain Remover, private label, samples, MOQ, documents, and delivery.
Product, use, and procurement
Can I use it on cups I drink from?
Yes, then rinse well. Sodium percarbonate breaks down into washing soda, water, and oxygen; rinse thoroughly with clean water after soaking before using the cup.
Can I use it in a clay teapot?
We don't recommend it. Many people season clay teapots on purpose, and porous clay can hold onto residue.
How do samples and minimum orders work?
Free samples ship in 3–5 days. MOQ and lead time depend on the spec and packaging, and we confirm both once those are set.
Product usage questions
How do I use it?
Dissolve one scoop (about 10 g) per 17 oz of water at 140°F or hotter, soak 15–30 minutes, brush lightly, and rinse.
When shouldn't I use it?
Not for aluminum, unglazed clay teapots, or hand-painted or gilded china; never mix with chlorine products.
Can I use cold water?
Active oxygen releases very slowly in cold water; 140°F or hotter works best.
Can I soak a coffee carafe?
Glass and stainless carafes, yes; descale the machine's internals with a coffee machine descaler.
Will cups taste or smell afterward?
Not after a thorough rinse; they're ready to use.
How do I clean tea strainers and spouts?
Submerge them, then brush the inside of the spout with a small brush and rinse.
Can I use it on insulated tumblers?
Yes. Soak stainless tumblers and rinse.
Can I use it on glass teapots?
Yes, glass and ceramic teaware both.
How often should I use it?
Weekly for teaware used daily.
Should I add dish soap?
No need; soak and rinse.
What actually removes tea and coffee stains from mugs?
Oxygen does the heavy lifting. This cleaner is based on sodium percarbonate, which releases active oxygen in hot water and breaks down the brown tannin and coffee pigments stuck to the cup wall. Dissolve it in water at 140°F or hotter, soak, brush lightly, and rinse.
Why do tea and coffee leave such stubborn stains in cups?
Both drinks carry tannins and dark pigments that cling to glazed ceramic and stainless steel, and every cup adds a thin new layer on top of the last. A quick rinse never reaches the bottom layer, so the ring keeps getting darker. A hot oxygen soak loosens the layers so a soft brush can lift them.
What if a stubborn stain is still there after one soak?
Brush off whatever has loosened, then soak again in a fresh hot batch. Thick buildup comes off layer by layer, and a cooled solution releases oxygen much more slowly, so a new mix beats topping off the old one. A weekly soak keeps it from building back up.
OEM/ODM customization questions
What can we customize?
Formula direction, scent, pack size and format, label design and language, and ecommerce bundles.
What paperwork comes with a private-label order?
Documents such as SDS/MSDS, TDS, COA, and label copy for your target market are prepared per project. We confirm which ones your order includes when we quote.
