Set-in stains rarely wait for your laundry schedule to cooperate, and store-bought pre-treaters can cost far more than a simple wash-day helper should. This homemade pre-wash spray gives you a ready-to-grab bottle for treating clothes before they hit the washer (because spaghetti sauce never clocks out politely).
A comparable commercial stain pre-treater usually costs several dollars for one spray bottle, while this batch uses basic household supplies you may already keep on hand and makes a much larger amount for less per ounce. Making your own also lets you control the scent and skip extra dyes or fragrance boosters that do not help the actual job.
You only need 4 materials for this formula: household ammonia, baking soda, white vinegar, and water. The mixture goes into a plastic spray bottle, and you’ll also want a measuring cup and spoon for combining everything before use.

Customization Ideas
This formula is straightforward, but you can still make it work better for your routine.
- Small laundry room setup: Mix the batch in a larger container first, then refill a smaller spray bottle for easier handling.
- Shared household setup: Label the bottle clearly so nobody mistakes it for a general-purpose cleaner.
- Budget batch system: Keep one bottle near the hamper and one near the washer if you regularly treat school clothes, work shirts, or kitchen towels.
Safety Information
Keep this spray in a clearly labeled bottle and use it with good ventilation. Do not mix it with bleach or use it alongside bleach-based laundry products. The CDC notes that household ammonia can release gas if mixed with certain other cleaning products, so this is one bottle you want to keep simple and well marked.
Storage
Store the spray in its plastic bottle with the contents labeled clearly. Keep it out of reach of children and away from heat or direct sunlight.
Estimated Cost
This batch is estimated at about $1.70 to $2.50 in consumable materials, depending on the brands you buy and local prices. That estimate covers the ammonia, baking soda, white vinegar, and water used in the formula, but it does not include the reusable spray bottle.

Frequently Asked Questions about Pre-Wash Spray
Use a plastic spray bottle, since that is the container specified for this formula. Label it clearly and keep it only for laundry use.
The formula includes 1/2 cup household ammonia, 1/4 cup baking soda, 1/2 cup white vinegar, and 1/2 gallon water, so it makes a fairly large batch. Plan on mixing it in a bottle or container that can handle more than a standard small spray bottle.
That is a smart habit, especially if the mixture has been sitting for a while. A quick shake helps redistribute everything before you spray.
Spray liberally onto clothes as needed, then wash as usual. This is a pre-wash treatment, so use it before the clothing goes into the washer.
No. Do not mix or pair this spray with bleach or bleach-based products. Keep the two completely separate.
Yes, if you want a smaller amount, halve each ingredient evenly and keep the same proportions. That makes the batch easier to fit into a smaller bottle.
Absolutely. A clear label helps prevent mix-ups, especially in a laundry room where multiple spray bottles tend to gather like uninvited cousins.
This formula is presented as a pre-wash laundry spray, so stick to that job. Keeping it dedicated to laundry also reduces the chance of accidental misuse.
Mix the formula in a larger container first, then refill the spray bottle as needed. That is often the easiest way to manage a larger homemade batch.
