100% food-grade descaler for kettles, baby bottle warmers, and food-contact items. No EDTA, no BTA - just acids and gluconate that are safe around water you'll drink.
100% food-grade ingredients (E330, E296, E334, E576, E551)
Pure citric / malic / tartaric + sodium gluconate
Built for kettles, baby bottle warmers, and food-contact appliances
No EDTA, no BTA - safer for direct boiling water
Hard-water scale builds quietly inside appliances. Use the descaler that matches the job, and remove buildup before it slows heating, blocks flow, or leaves appliances smelling off.
WHY BIO
Bio uses only food-additive ingredients (E-numbers across all acids and gluconate). The trade-off: no metal corrosion inhibitor, so it should not be used in machines with brass internals like most espresso machines.
Do not use on espresso machines with brass internals - use DescaleX Coffee instead (BTA-protected).
Empty appliance only. Rinse fully with fresh water before next use.
Use gloves and keep the sachets dry until use.
INGREDIENTS
Citric acid anhydrous (74.15%)
Malic acid (9%)
Tartaric acid (8%)
Sodium gluconate (9%)
Silicon dioxide (0.5%)
CUSTOMER REVIEWS
“Feels right for the kettle”
Bought Bio for our electric kettle. No weird smell after rinsing, no residue, and the food-contact positioning actually matters for drinking water.
“Simple measured sachets”
One sachet cleaned the kettle without guessing powder amounts. The separate Bio formula makes more sense than using coffee-machine chemicals in drinking-water appliances.
“Good for baby bottle warmer”
Used it on our bottle warmer and rinsed fully. Scale cleared without a strong chemical smell.
Which DescaleX should I use for my kettle?
Common question
Use DescaleX Bio for electric kettles, baby bottle warmers, stovetop kettles, and any other food-contact item. Bio is 100% food-grade with no corrosion inhibitor, which is the right choice for direct boiling-water contact.
Which DescaleX should I use for my coffee or espresso machine?
Common question
Use DescaleX Coffee. It includes BTA, the corrosion inhibitor that protects the brass and aluminium internals most coffee and espresso machines depend on. Coffee is also the right choice for dishwashers and showerheads.
Which product should I use for a washing machine or geyser?
Common question
Use WashDX. It is the heavy-duty machine-side formula with sulfamic acid for hard scale, BTA for aluminium spider-arm protection, and the bleach-gap and empty-drum warnings that washing machines, geysers, boilers, water tanks, and immersion rods need.
How many maintenance jobs does one WashDX pack cover?
Common question
One WashDX box is 100g and covers two 50g maintenance jobs. Web packs are available as x1, x2, x3, and x6.
