Frequently Asked Questions

How much detergent should I use per wash?

Standard load (3–4 kg): 1–2 tablespoons powder/liquid. HE machines: half that amount. More is not better — excess detergent leaves residue on clothes, causes musty odor, and damages the machine over time.

What is the cost per washing machine load?

A typical front-loader uses 0.5–1 kWh electricity (₹4–8) and 40–60 liters water (₹2–4). Adding detergent (₹5–10) gives total cost of ₹11–22 per load. Top-loaders use 2–3× more water.
