π§Ί Hard Water Laundry Cycle β Quick Card
1. Wash Fill (Hot water, 10β15 gal)
- 2β3 tbsp washing soda

- Normal bottled detergent
- Plunge / soak 15β30 min if needed
2. Drain
3. Rinse #1 (Warm water)
- Everyday loads β Β½β1 cup vinegar, plunge
- Heavy soil β 1 tbsp washing soda, plunge (no vinegar here)
4. Drain
5. Final Rinse (Warm water)
- Everyday loads β plain water, light plunge
- Heavy soil β Β½β1 cup vinegar, light plunge
6. Wring
- Catch wring water in tub β top up with hot water + boosters β use for next wash fill
7. Hang/Dry
- Line + fans in living room
- Rack + dehumidifier in bedroom
πΉ Standard Tub Recipe (for a clawfoot tub load, ~Β½ full)
-
Hot Fill (10β15 gallons, roughly knee-deep in the tub).
-
Washing Soda β 2β3 tablespoons.
- Stir or plunge to fully dissolve (this softens the hard water).
-
Sodium Percarbonate β 1β2 tablespoons.
- Add once water is softened and hot. Dissolve fully.
-
Detergent β normal dose of your bottled liquid (about what youβd use in a medium machine load).
- Add after boosters are dissolved, then plunge to mix.
-
Clothes β push them under and start plunging/agitating.
Exactly π β youβve got the sequence right. Letβs nail down the amounts so youβve got a go-to recipe:
πΉ Notes on Ratios
- 2 tbsp washing soda : 1 tbsp percarbonate = good for normal laundry in hard water.
- For whites/towels/smelly loads β bump percarbonate to 2β3 tbsp.
- For darks/delicates β keep percarbonate light (Β½β1 tbsp) or skip, since oxygen bleach can fade colors over time.
πΉ Key Steps
- Always dissolve washing soda first β it βclearsβ the hard water.
- Add percarbonate next β so its oxygen isnβt wasted fighting minerals.
- Soap last β so it can actually do its job with softened, oxygenated water.
πΉ NO vinegar and washing soda β they cancel eachother out
π§Ί Hard Water Optimized Laundry Cycle (Clawfoot Tub)
1. Wash Fill
-
Fill tub ~Β½ full with hot water (10β15 gallons).
-
Add 2β3 tbsp washing soda β dissolve fully (softens the water).
-
Add 1β2 tbsp sodium percarbonate β stir until dissolved (oxygen cleaning power).
- Whites/towels/stinky loads: use 2β3 tbsp.
- Darks/delicates: Β½β1 tbsp or skip.
-
Add your normal bottled detergent β medium-load dose.
-
Plunge/agitate clothes thoroughly.
-
Let soak if needed (15β30 min for heavy soil).
2. Drain
- Dump dirty, soapy water.
3. Rinse Fill #1
-
Refill tub with hot or warm water.
-
Optional: Add Β½β1 cup vinegar.
- Neutralizes detergent.
- Softens fabric.
- Deodorizes.
-
Plunge/agitate again.
4. Drain
- Dump sudsy/vinegar rinse water.
5. Final Rinse Fill
- Refill tub with plain hot or warm water.
- Plunge lightly to flush out last traces of detergent/vinegar.
6. Wring
- Feed all clothes through wringer.
- Catch wring water in the tub β use as starter water for the next wash fill (top up with hot + fresh detergent/boosters).
7. Hang/Dry
- Living room clothesline with fans + open windows.
- Bedroom rack with ceiling fan + dehumidifier.
- Clothes dry in ~1 day even for big loads.
β This is the go-to cycle: detergent + washing soda + percarbonate in the wash β vinegar in the first rinse β clean water in the final rinse β wring β reuse wring water for next batch.
