GOOD QUESTIONS. CLEAR ANSWERS.

Before you
check out.

Can’t find your answer?
Send us a question.

Can EfferSan treat livestock drinking water?

Yes. EfferSan’s EPA master label includes drinking-water disinfection for poultry, swine, cattle and other livestock. Check the corresponding directions on your bottle, including dilution, monitoring and any restrictions. Read the livestock drinking-water section (PDF).

Are these hypochlorous acid tablets?

EfferSan tablets contain sodium dichloro-s-triazinetrione (NaDCC), which releases hypochlorous acid (HOCl) when dissolved in water. They are sold as a dry concentrate, not a ready-to-use liquid. Follow the product label for the intended application.

How many tablets do I add to my animals’ water?

The amount depends on tablet weight, water volume, water condition and the labeled treatment concentration. This store sells 17.68 g tablets. Use your bottle’s livestock drinking-water dilution chart and monitoring directions. A dose for a 4 g tablet or for surface disinfection is not interchangeable.

Can I use livestock directions for every animal?

Use EfferSan only for the animals and applications covered by your product label. Livestock drinking-water directions should not be assumed to cover aquariums, fish or every pet species.

How will my order ship?

Free FedEx 2Day shipping is available to the contiguous United States (48 states). We dispatch orders within two business days. FedEx transit is typically two business days after it receives your package. Weekends, holidays, and service exceptions can affect delivery. FedEx’s transit time is separate from our handling time. Read shipping and return details.

What is your 60-day satisfaction guarantee?

Request a return for any reason within 60 days of delivery—even if you’ve opened the bottle—for a full refund of the product price. We issue refunds to the original payment method within five business days after receiving your return. Contact us first for return instructions. You pay return postage for a change of mind; we cover any required return shipping for damaged or incorrect items. Read our for details.

Can I pay by card?

You’ll leave this site to complete payment on PayPal. The checkout page displays the payment methods available for your transaction, which can include debit or credit cards. Availability is determined by PayPal.

Which EfferSan size am I buying?

One bottle containing 100 tablets, with each tablet weighing 17.68 g. The manufacturer part number is 17686. This store sells this size only; it is not the 4 g tablet bottle.

Is Sanitizer Depot the manufacturer?

No. Sanitizer Depot is an independent retailer selling EfferSan. We handle your order and shipment. The manufacturer’s site is linked in our directions and safety resources.

What is the 36% savings compared with?

On October 16, 2026, the manufacturer listed the EfferSan 17.68 g, 100-count bottle at $125.00. Our $79.95 price is $45.05 lower, or approximately 36% less. This compares product prices and is not a claim about our previous selling price. Manufacturer prices can change. View the manufacturer’s product page.

Are sanitizing and disinfecting the same?

They are different applications with different label requirements. The concentration, preparation, contact time, and any rinsing steps depend on the intended use. Follow the directions on the bottle you receive rather than using one dilution for every task.

How much solution does a bottle make?

The amount depends on the application and the required dilution. A bottle contains 100 tablets of 17.68 g each. Use the dilution chart on your bottle to calculate the amount for your task; there is no single yield that applies to every use.

Do I need to rinse after using EfferSan?

Rinsing requirements depend on the application. A no-rinse sanitizing direction does not apply automatically to disinfecting or other uses. Check the surface, concentration, contact time, and rinsing directions on your product label.
