See the difference
Scale doesn’t just look ugly. It blocks flow.
One descale cycle. The same coffee machine, kettle, or showerhead. Drag the handle left and right to see what hard water buildup looks like - before, and after.

Inside the formula
Every ingredient earns its place.
Start with the job the formula does for the appliance. Then go deeper ingredient by ingredient if you want the science.
Chelant support
Chelants keep dissolved minerals suspended so they rinse away instead of settling back on the appliance.
BTA metal-support system
Metal-support additives help the formula target scale without being harsh on the appliance internals.
01
Primary acid
Citric Acid
The bulk acid that dissolves calcium and magnesium scale. Food-grade, biodegradable.
02
Hard scale + rust
Sulfamic Acid
Cuts through rust-integrated scale that citric alone cannot dissolve. Capped at 14% to stay safe on EPDM rubber gaskets.
03
Hot-cycle acid
Fumaric Acid
Activates at 60 deg C+ in the wash cycle. Cost-optimised vs malic since cold solubility doesn't matter in a hot drum.
04
Chelant
Sodium Gluconate
Holds dissolved calcium and magnesium in solution so they wash out instead of redepositing on the drum or heating element.
05
Iron chelant
Disodium EDTA
Specifically targets iron deposits common in borewell water. Removes the orange-brown staining citric acid alone can't touch.
06
Aluminium protector
BTA
Protects the aluminium spider arm - the #1 washing machine failure point in hard water areas. Acid attacks the scale, not the metal.
How to use
One sachet. One cycle. No measuring drama.
Dose, frequency, and warnings change based on what you’re descaling. No guesswork.
Washing Machine
- 1Empty the drum completely. No clothes, no detergent, nothing inside.
- 2Tear open one sachet. Pour directly into the empty drum.
- 3Run the hottest available cycle (60 deg C or above), max 60 minutes.
- 4Immediately follow with one plain cold rinse cycle.
- 5Wipe the door seal with a damp cloth after.
Warning: Do NOT use within 24 hours of any bleach cycle - chloramine gas risk. Empty drum only - never with clothes.
Dose
1 sachet (50g)
Frequency
Every 2-3 months
Rinse cycles
1 plain rinse cycle
Background
Why hard water destroys appliances.
Tap to expand. The science, plain.
The aluminium spider arm holds the inner drum to the rear bearing. In hard water, dissolved calcium combined with detergent residue forms a galvanic cell with the aluminium - slowly corroding it. Within 4-6 years in 400+ TDS conditions, the spider arm cracks, the drum wobbles, and the bearings fail. Spider arm replacement costs Rs.6,000-12,000 and is rarely worth it. Descaling every 2-3 months with BTA-protected WashDX prevents the corrosion chain from starting. This single habit usually doubles the life of a washing machine in Indian conditions.
Washer and geyser scale is usually mixed buildup, not a clean lab sample of limescale. WashDX is built for that real-world appliance residue: mineral load, heat-cycle buildup, and the kind of repeat maintenance common in hard-water homes.
One 50g sachet is the standard dose for a washing machine, geyser, or boiler at 200-600 TDS, descaled within the last 3 months. Use 2 sachets for: TDS over 600, no descaling in 6+ months, visible white scale or rust staining, borewell water with orange tint, or geysers and boilers larger than 25L. Doubling on the first cycle saves you running back-to-back descales.
WashDX is meant to descale, not to smell perfumed or imitate a detergent cleaner. Keeping the formula focused helps avoid unnecessary foam and keeps the cycle easier to manage in washers, heaters, and tanks.
Drum-clean sachets are alkaline and surfactant-based. They clean organic residue - detergent buildup, mould, and that musty smell. WashDX is acid-based. It removes mineral scale and rust. If your machine smells, a drum-clean solves it. If it heats slowly, takes longer to reach temperature, or has visible white-grey crust on the element, that is a WashDX problem. Using a drum-clean for a scale problem does nothing. Pick by symptom.
Safe: stainless steel, plastic drum liners, rubber EPDM gaskets (sulfamic capped at 14%), aluminium with BTA protection, glass, ceramic. Caution: old or cracked rubber seals. Do not use on: clothes or fabric, baby appliances or food-contact items (use DescaleX Bio), natural stone, cement-lined tanks. Never within 24 hours of a bleach cycle.

Built for Indian hard water, not soft-water manuals.
Indian water hardness varies wildly between cities, even neighbourhoods. We tell you exactly how often to descale based on your TDS.
Below 200
Soft. Descale every 4-6 months.
200 - 400
Moderate. Descale every 2-3 months.
400 - 600
Hard. Descale every 6-8 weeks.
600+
Very hard. Every 4-6 weeks. Double dose first time.

Honest answers
Questions before you buy.
Do NOT use WashDX within 24 hours of running any bleach or chlorine-based cycle. Mixing acids with bleach produces chloramine gas, which is dangerous. If you've recently bleached, run a plain water cycle, wait a full 24 hours, then descale. After descaling, you can use bleach again on the next cycle if you want - just not before.
No. The BTA in the formula forms a protective layer on the aluminium spider arm during descaling - that's the part most likely to corrode in hard water. Sulfamic acid is capped at 14% to stay below the threshold that damages EPDM rubber door seals. The full rinse cycle after washes everything clean. Used as directed, it's safer than vinegar and most generic descalers.
Both. The formula and dose are identical. Front-loaders may show more visible benefit because the door glass and gasket also get cleaned during the cycle. Top-loaders typically have heavier scale on the heating element.
They solve different problems. Drum-clean tablets focus on detergent residue and odour. WashDX focuses on mineral scale and heater-side buildup. Pick the route by symptom, not by whichever cleaner is already in the cupboard.
For dishwashers, use DescaleX (the regular formula) instead. WashDX is built for the high-temperature, no-food-contact environment of washing machines, geysers, and boilers. DescaleX has a food-contact-rinse-safe profile that's better for dishwashers.
One cycle. Heating times improve immediately - most machines that took 20+ minutes to reach 60 deg C return to 12-14 minutes after a single descale. Visible scale starts coming out as cloudy water during the rinse cycle.
