The archive contains a two-gallon written baseline, not an absence of measurements. It lists 1/2 cup liquid Castile soap, 1/2 cup washing soda and 1/2 cup borax. Earlier attached advice also used 1/4 cup of each builder. Those variants must not be silently merged.
Ingredients
Recorded baseline: 2 gallons water plus the listed ingredients; not an exact measured final yieldCheck off each item as you go.
Recorded process
Historical steps only. Missing quantities must be resolved before this can be a repeatable formula.
Read the batch distinction first
These are the written baseline proportions, not a family-validated correction for damaged laundry. The preferred batch and normal dose have not been independently established.
Recorded mixing sequence
The earlier preparation dissolved the washing soda and borax in part of the hot water, allowed the solution to cool to warm, then stirred in Castile soap and the remaining water.
Do not carry unsafe additions forward
The stored liquid does not include sodium percarbonate. Keep an oxygen cleaner separate and follow its product label. Do not add citric acid, vinegar or lemon juice to this soap mixture.
Resolve the actual use conditions
Before any new trial, record the exact ingredient weights, total water, washer requirements, water hardness and intended dose. Do not resume a damaging routine or assume that a homemade soap meets an HE-only machine requirement.
Safety & handling
- Do not store an oxygen-cleaner solution in a tightly sealed container: oxygen release can build pressure.
- Acids can break down true Castile soap; the acid additions in old conversations are not validated improvements.
- This household observed fabric deterioration. A recovered written recipe is not a successful retest or an appliance compatibility assessment. Keep cleaning materials labeled and inaccessible to children.
Troubleshooting
- Fabric edges or rims breaking down: stop the current formula and auxiliary oxidizers while investigating; compare a simple control wash before resuming.
- Do not directly combine vinegar and hydrogen peroxide. Their repeated use alongside a highly alkaline wash also makes the cause of fabric damage difficult to isolate.
- Dull colors: Heather tried 2 tsp citric acid, but the outcome was unresolved. Citric acid may neutralize the alkaline builders or destabilize Castile soap, so do not present it as a proven fix.
- Separation, curds, or an oily layer: suspect acidification of the Castile soap or incompatible concentrations; discontinue that batch rather than adding more ingredients.
- Residue or stiffness: possible causes include excessive soap, hard-water soap deposits, too much washing soda or borax, or inadequate rinsing.
- Poor stain removal: do not compensate by continually increasing the stored soap concentration. Treat stains separately or use a compatible dry oxygen cleaner as directed.
- Continued fabric deterioration after simplifying the chemistry: assess machine abrasion, overloaded loads, garment age, heat, and repeated wear at hems and edges.
Insider tips
- Label written proposals and actual batches separately; the phrase "the recipe" concealed several different formulas.
- Keep a sample label or photograph with each exact batch so a favorable or unfavorable outcome can be assigned to the right version.
- Do not adjust several additives at once when investigating an adverse result.
The recorded variants, kept separate
- Earlier attached base: 2 gallons water, 1/2 cup Castile, 1/4 cup washing soda and 1/4 cup borax.
- Later written base: 2 gallons water, 1/2 cup Castile, 1/2 cup washing soda and 1/2 cup borax.
- The original March discussion also listed a proposed version with 3 tablespoons citric acid, 1/4 cup sea salt and 1 tablespoon glycerin. That proposal is not the validated current formula.
- Heather separately reported trying 2 teaspoons citric acid and 1 tablespoon glycerin. That is a different record from the assistant's acid/salt proposal.
- A later statement that oxygen cleaner could safely be stored in the liquid conflicts with manufacturer warnings and is not retained as an instruction.
Family notes
- The family had made about six batches and liked the soap overall before the later fabric-damage observation.
- Heather values having one dependable product, knowing what is in it, receiving the same result, and keeping the finished product visually simple.
- Heather added 2 tsp citric acid in response to dull colors and 1 Tbsp glycerin; no clear benefit or harm was established.
- Later, whites, towels, linen shorts, and pants were reported to be falling apart around rims or edges.
- Vinegar was being used in the fabric-softener compartment and hydrogen peroxide in the bleach compartment when the damage was noticed.
Background & original notes
The archive contains a two-gallon written baseline, not an absence of measurements. It lists 1/2 cup liquid Castile soap, 1/2 cup washing soda and 1/2 cup borax. Earlier attached advice also used 1/4 cup of each builder. Those variants must not be silently merged.
The family made several batches they liked, then reported damage around the edges of some fabrics while other additives were also being used. The source does not identify a validated final formula or establish the cause. Stop a routine associated with fabric damage and follow the washer manufacturer's detergent requirements rather than treating this recovered record as a proven replacement.
Historical acid, salt and oxygen-cleaner proposals are preserved in the notes. They are not included in the baseline below. In particular, do not store sodium percarbonate mixed into a capped liquid jug, and do not assume that adding acid to true soap is an improvement.
Sources & what was completed
Record provenanceReviewed against original conversation text and attachments on September 27, 2026. Recorded family outcomes, original assistant proposals, and current editorial completion are distinguished below.
- Dr. Bronner: acids and true soap
- OxiClean: never seal a prepared oxygen-cleaner solution
- Samsung: HE detergent requirements are appliance-specific
- The four baseline quantities and water volume were recovered from original conversation/attachment text.
- The preferred family variant, established load dose and a successful retest after fabric damage remain unresolved.
- Storage and acid-compatibility corrections were checked against manufacturer guidance; they are not claimed to be family-tested.
