Steps to clean pipes​

  1. Boil Water.
  2. Add Baking Soda: Pour about 1/2 cup of baking soda down the drain.
  3. Add Vinegar: Follow with 1 cup of vinegar. You will see fizzing as the two react.
  4. Cover the Drain: Place a drain plug or cloth over the drain to keep the reaction concentrated.
  5. Wait: Let the mixture sit for 10-15 minutes.
  6. Flush with Hot Water.

Laundry softener​

Citric acid can be used as a fabric softener substitute because it helps neutralize alkaline detergent residues and can reduce stiffness caused by hard water minerals.

Method 1: Citric Acid Fabric Softener Solution​

  1. Dissolve 25–50 g of citric acid powder in 250ml liter of warm water.
  2. Store the solution in a labeled bottle.
  3. Add 30–60 mL (2–4 tablespoons) to the fabric softener compartment of your washing machine for a normal load.

Method 2: Direct Use​

  1. Add 1–2 tablespoons (15–30 g) of citric acid powder directly to the fabric softener compartment during the rinse cycle.

Do not put dry citric acid directly onto clothes.

Benefits:

  • Softens fabrics without coating fibers.
  • Helps remove detergent residue.
  • Reduces mineral buildup in hard-water areas.
  • Usually leaves towels more absorbent than conventional fabric softeners.

Important Precautions:

  • Do not mix citric acid with chlorine bleach.
  • Avoid excessive concentrations, as highly acidic solutions may contribute to corrosion of some washing machine components over long periods.
  • If your washing machine manufacturer advises against acidic rinse additives, follow the manufacturer's guidance.
  • Test on delicate or specialty fabrics if you're concerned about colorfastness.

For most households, a 10–20% citric acid solution used in the softener compartment is a practical and widely used approach.
