Pre-Soak (for whites and colorfast fabrics)

Dingy whites and set-in laundry grime don’t need an expensive specialty treatment to come clean. This simple pre-soak gives white cottons and bleachable colorfast fabrics extra help before they ever hit the washer (because sometimes detergent alone just waves politely and walks off). It uses a short ingredient list and a basic bucket setup you can mix in minutes.

Making your own batch costs only a fraction of a single-use commercial stain-soak tub. Using current Walmart pricing, 1/2 cup automatic dishwasher detergent and 1/2 cup chlorine bleach works out to about $0.78 per batch, while store-bought laundry soaks typically cost more per treatment. You also control the strength, the water temperature for whites versus colorfast items, and exactly what goes into the soak.

You only need 3 materials for this batch: hot or cool water, automatic dishwasher detergent, and chlorine bleach. The original method makes one 5-gallon bucket batch of soaking solution using a 5-gallon bucket, with no extra gear required beyond something to measure the ingredients and the bucket itself.

How to Make and Use the Pre-Soak

3. Combine all ingredients in the bucket until the detergent is dissolved.
4. Add white cotton items and soak them for 2 or more hours.
5. If you are soaking bleachable colorfast colors, use cool water instead of hot.
6. Remove the clothing from the bucket, wring it out, and wash as usual.

How to Use It

This pre-soak works best when you use it as a laundry boost before a regular wash cycle. It is intended for white cottons and for bleachable colorfast fabrics only.

Check the garment care label first. If you are not sure whether a colored item is truly bleach-safe, test a hidden area before soaking. For bleach use in laundry, keep the area ventilated and follow the product label directions. The Clorox colorfastness test method offers a practical way to check questionable fabrics before you commit the whole garment to the bucket.

If you need a gentler option for fragile items, try Pre-Soak for Delicate Fabrics. For extra whitening help on stubborn laundry, Whitening Soak is another useful option to keep in your laundry lineup.

• Use cool water for bleachable colorfast colors, exactly as directed.
• Do not use this soak on wool, silk, spandex, leather, or non-fast colors.

Storage

Mix this pre-soak when you are ready to use it rather than storing leftover solution. Chlorine bleach solutions lose strength over time, so a fresh batch gives you the most reliable results on laundry day.
