The Kleen-Tank Method vs. Professional Black Tank Treatments: Which Wins for RV Owners?

When it comes to black tank care, RVers are always looking for reliable RV tank cleaning tips and DIY black tank cleaning ideas. One popular method growing in popularity is the Kleen-Tank Method—a DIY approach using homemade “tank bombs” crafted from Borax, baking soda, and citric acid. But how does this natural method compare to professional black tank treatments like those from Walex? Let’s dig in.


The Kleen-Tank Method: A DIY Natural Solution

The Kleen-Tank Method involves making cleaning bombs with household ingredients. You mix Borax, baking soda, and citric acid with a few drops of water, form the mixture into balls, and let them dry. Once hardened, you drop the bomb into your freshly emptied black tank along with a few gallons of water. The motion of travel helps the bomb foam up, gently cleaning your tank walls and sensors.

Pros:

  • Eco-Friendly RV Sanitation: No harsh chemicals; just natural cleaning ingredients.

  • Cost-Effective: Ingredients are cheap and easily found at grocery stores.

  • Easy to Make: Once you get the hang of it, mixing and molding the bombs is straightforward.

  • Promotes Natural RV Cleaning Solutions: Appeals to RVers who prefer greener lifestyles.

Cons:

  • Limited Effectiveness: DIY bombs may not break down tough waste or remove heavy sensor buildup.

  • Time-Consuming: Requires time to mix, mold, and dry the bombs before use.

  • No Odor Control: Offers minimal odor protection compared to professional treatments.

  • No Lubrication for Valves/Seals: Could lead to future maintenance issues without regular lubrication.
