SOAP DROPS FOR WATER TESTING
Visually demonstrates the difference between hard and soft water using a simple soap reaction test. Just add a drop, shake, and observe—lasting suds indicate softer, low-mineral water, while weak or minimal foam signals harder water. It’s an easy, hands-on way to confirm your system is delivering the soft water experience you expect.

Durable & Long Lasting
Result Type: Visual comparison of foam formation and longevity.
Operation: Single-drop application with immediate results.
Ideal For: Home demonstrations, system verification, technician demos, and water softener performance checks.
See the Difference: Hard vs. Soft Water
Use a simple drop-and-shake soap test to visually confirm water softness—more lasting suds typically means softer, lower-mineral water.
Instant Visual Proof
Add a drop, shake, and watch the suds. Strong, lasting foam typically indicates softer water; weak foam suggests harder water.
Drop-and-Shake Simplicity
No tools or setup required. It’s a quick, hands-on test anyone can do at the sink in seconds.
Great for Demonstrations
Perfect for homeowners and technicians who want a quick way to show the real-world difference between hard and soft water.
Helps Verify System Results
Use it before and after treatment to validate that you’re getting the softer-water experience you expect for washing, rinsing, and skin feel.

FAQs
Answers about using the ALKAVIDA Soap Dropper to visually compare hard vs. soft water and confirm your system’s results.
What do the Soap Drops test for?
This is a visual soap reaction test that helps you compare how water behaves with soap. Softer water typically produces more lasting suds, while harder water often produces less foam due to mineral content.
Is this a lab test for specific contaminants?
No. It’s a quick, hands-on demonstration to compare water softness/hardness behavior with soap. It does not identify specific contaminants (like lead, PFAS, bacteria) or provide a certified measurement.
How do I use the Soap Dropper?
Fill a clear cup or bottle with your water sample, add one drop, cap or cover, then shake for 5–10 seconds. Observe foam height and how long the suds last.
How do I compare “before vs. after” results?
Test your tap water first, then test your treated/softened water using the same container size, same water volume, and the same shaking time. The comparison is the proof.
What does “more suds” mean?
More foam and longer-lasting suds typically indicates softer water (lower hardness minerals), which often improves soap performance and rinsing feel.
What does “less suds” mean?
Minimal foam or suds that collapse quickly often suggests harder water. Hardness minerals can bind with soap and reduce lathering.
Why might results look different from day to day?
Seasonal source-water changes, water temperature, container cleanliness, and soap residue can impact foam. For consistency, use cold/room-temp water, clean containers, and the same shake time.
Where should I test—kitchen, bathroom, or outside spigot?
Test wherever you want to compare performance. Many people check kitchen tap vs. treated water, or compare different faucets (especially if some lines bypass treatment).
Can I use it for RV or travel water?
Yes. It’s a quick way to compare water at different locations and get a visual sense of soap performance with that source.
How do I store the Soap Dropper?
Keep it capped tightly, store upright, and avoid extreme heat or freezing. Wipe the tip clean after use to prevent buildup.
How many tests can I do?
It’s designed for multiple demonstrations. Exact number depends on drop size and how many drops you use per test (typically one drop is enough).
This is a visual soap reaction test intended to compare water behavior (hard vs. soft). It does not identify specific contaminants or provide a certified laboratory measurement.
