Gray dingy whites make the whole laundry pile look tired, and a quick soak fixes that before you waste detergent on a regular wash cycle. This whitening soak is a simple bleach-and-detergent presoak for washable white items that need a brighter reset. It takes a few minutes to mix, and your bucket does most of the work (finally, something in the house does).
Making your own soak costs less per batch than buying a separate whitening booster. Using current Walmart pricing, 1/4 cup of liquid chlorine bleach from a 121-ounce bottle at $5.88 costs about $0.10, and 1 cup of powdered dishwasher detergent from a 75-ounce box at $5.43 costs about $0.72, so one batch runs about $0.82. That gives you control over the strength and scent because you choose the bleach and detergent you already keep on hand.
You only need 3 materials for this mix: liquid chlorine bleach, powdered dishwasher detergent, and hot water. The formula makes 1 batch and the original method calls for mixing it in either a 5 gallon bucket or the kitchen sink, so the only equipment you genuinely need is one of those containers plus a measuring cup.

How to Make a Whitening Soak
- Combine 1/4 cup liquid chlorine bleach, 1 cup powdered dishwasher detergent, and 1 gallon hot water in a 5 gallon bucket or the kitchen sink.
- Add the white washable items you want to brighten.
- Soak the items for 20 minutes.
- Launder as usual.
Customization Ideas
- Use the 5 gallon bucket when you want to soak several small white items at once.
- Use the kitchen sink when you only need to treat a smaller batch and want easier cleanup.
- Keep this soak for white washable items only. If you need a gentler option for other fabrics, take a look at Pre-Soak (for delicate fabrics).
- If socks are your main problem, you might also like White Sock Soak.
How to Use It
Use this soak when white items look dingy, yellowed, or generally worn out from regular laundering. The short presoak helps loosen buildup before the wash cycle, which is why it works well as a reset treatment instead of an every-load habit.
After the 20-minute soak, wash the items as usual with your regular laundry routine. If you work through a lot of homemade household fixes, you may also want to browse Household Recipes for the Do it Yourselfer for more mix-it-yourself basics.
Safety Information
Use this soak only in a well-ventilated area, wear gloves if your skin reacts to bleach, and never mix bleach with ammonia or other household cleaners. The CDC also advises against mixing household bleach with other cleaners or disinfectants because dangerous vapors can form. You can read that guidance here: Cleaning and Disinfecting with Bleach.
This formula is best reserved for washable white items. Do not use it on colored fabrics, and do not store the mixed solution for later use.
Storage
Mix this soak right before you need it, use it immediately, and discard the used solution when you’re done soaking the laundry. Keep the original bleach and powdered detergent in their own labeled containers with lids closed tightly between uses.
Cost Breakdown
- 1/4 cup liquid chlorine bleach: about $0.10

Soak the items for 20 minutes, then launder them as usual. There is no need to stretch the soak into an all-day science experiment.
No. The original method uses either a 5 gallon bucket or the kitchen sink. Pick the one that fits the amount of laundry you need to treat.
No. Mix it right before use and discard it after the soak. This works best as a fresh, one-batch treatment.
In this formula, the powdered dishwasher detergent acts as the cleaning booster paired with the bleach and hot water. Stick with the measured amount in the formula instead of eyeballing it.
The directions simply say to soak the items for 20 minutes and launder as usual. If your normal wash routine includes a rinse as part of the cycle, that is typically enough.
No. Use the stated amount, which is 1/4 cup liquid chlorine bleach per gallon of hot water with 1 cup powdered dishwasher detergent. More is not automatically better, especially in laundry care.
