When dingy whites, grimy surfaces, or heavy cleanup jobs laugh at your usual cleaner, this old-school heavy-duty bleach formula steps in and gets to work. You mix it once, let it settle, strain it, and store it for later use. It is not fussy, but it does demand respect (which is cheaper than regret).
Do not get this on your skin or breathe the fumes. Keep away from pets/children, etc.
Making your own can cost less per batch than buying specialty bleach-based cleaners, especially if you already keep washing soda on hand. Based on current retail pricing, 1 gallon of this mixture works out to roughly $1.66 per batch using washing soda and chlorinated lime, and you control the concentration, container size, and labeling instead of paying for a pre-bottled product with a fixed format.
You only need 3 materials for this batch: water, chlorinated lime, and washing soda. The formula is mixed in a heavy plastic pail, then strained into covered containers and labeled after it sits uncovered for 24 hours, so have a strainer and storage containers ready before you start.

How to Make Heavy-Duty Bleach
- Carefully combine the water, chlorinated lime, and washing soda in a heavy plastic pail.
- Mix well until the ingredients are thoroughly combined.
- Let the mixture set uncovered for 24 hours.
- Strain the mixture into covered containers.
- Label the containers clearly before storing them.
How to Use It
Use this formula for heavy-duty household cleaning jobs where a bleach-based mixture is appropriate. Apply it carefully, keep the area ventilated, and avoid casual use on delicate surfaces or around fabrics you do not want lightened. If you want a milder option for routine cleaning, take a look at Bleach – Gentle Recipe or All Purpose Bleach Cleaner.
Safety Information
Do not get this on your skin or breathe the fumes. Keep it away from pets and children. Use it only in a well-ventilated area, and never mix bleach products with other cleaners. The U.S. Environmental Protection Agency specifically warns not to mix bleach with other household chemicals and recommends good ventilation when using cleaning products: read the guidance here.
Stick with heavy plastic for mixing, and do not use food containers for storage. Label every container clearly so nobody mistakes it for anything else.
Storage
After straining, store the finished mixture in covered containers with clear labels. Keep the containers out of reach of children and pets, and store them in an area where fumes will not build up around living spaces.
Estimated Cost
This batch is estimated at $1.66, not including reusable tools or storage containers you already own. That estimate uses current retail pricing for washing soda and chlorinated lime, and prices will vary by brand, region, and package size.
- Washing soda: about $0.88 for 3 cups
- Chlorinated lime: about $0.78 for 2 cups
- Water: not included

Frequently Asked Questions about Homemade Heavy-Duty Bleach Formula
No. Use covered containers that are clearly labeled, and do not reuse food containers. The original directions also specify mixing it in a heavy plastic pail, so stick with compatible non-food containers for the whole project.
Because that is part of the original method. The mixture is combined, mixed well, left uncovered for 24 hours, and only then strained into covered containers. If you skip that step, you are no longer following this formula as written.
This formula specifically calls for a heavy plastic pail. That is the best choice here. Bleach-related mixtures can react with some metals, so this is not the time to improvise with whatever bucket is wandering around the garage.
Yes. The method says to strain the mixture into covered containers after it rests. Straining helps remove remaining solids before storage and makes the finished mixture easier to handle later.
You can scale the formula proportionally if you have a large enough heavy plastic container and safe storage ready, but keep the same ratio of 1 gallon water, 2 cups chlorinated lime, and 3 cups washing soda per batch.
No. This is a heavy-duty bleach formula, not an all-purpose cleaner for every surface. Test carefully, keep it away from materials that can discolor, and choose a milder cleaner when the job does not need this much punch.
Stop using it right away and get fresh air. The original directions warn you not to breathe the fumes, so ventilation is not optional with this mixture.
No. Do not mix it with other cleaners. Bleach mixtures can produce dangerous fumes when combined with other household products, so stronger is not better here.
Label them clearly with the contents and keep them covered. The important part is that anyone who sees the container immediately knows it is a bleach mixture and not something to pour, touch, or sniff casually.
