We dropped one of these into the tank, filled per instructions and let the solution sit for approximately 12 hours. Emptied and tank flushed again and after a moment or two, the tank indicated as empty so it worked perfectly! The only think I wish is that these RV necessities would be less costly - on a cost per use basis, we are paying just over $4 per drop-in (after tax). True, you shouldn't need to use them very often but that's still a lot. They do work though, so I guess my mindset should be that you get what you pay for. ## Features - Pack of 4 COMMANDO Black Tank Cleaning Drop-Ins - Removes residual waste build up that can cause inaccurate sensor readings and residual odors - Removes odors and build-up in as little as 12 hours - Super-concentrated, scientifically developed formula with natural enzymes to penetrate and break down waste and paper build-up - Use to remove existing build-up or to prevent build-up accumulation ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B0177AJ64G | | Best Sellers Rank | #375,090 in Car & Motorbike ( See Top 100 in Car & Motorbike ) #29 in Cleaning, Storage & Maintenance | | Brand | Walex | | Brand Name | Walex | | Contains Liquid Contents? | Yes | | Country of Origin | USA | | Customer Reviews | 4.4 out of 5 stars 2,182 Reviews | | Global Trade Identification Number | 00742693500046 | | Item Form | Tablet | | Item Volume | 4 Cubic Inches | | Manufacturer | Walex | | Material Feature | Natural | | Material Features | Natural | | Material Type Free | Formaldehyde Free | | Model Number | CMDOBG | | Number of Items | 1 | | Part Interchange Info | CMDOBG | | Part Number | CMDOBG | | Scent | Ocean Mist | | Size | 4 count (Pack of 1) | | Special Features | Concentrated, Residue Free | | Specific Uses For Product | Toilet | | Surface Recommendation | Plastic | | UPC | 742693500046 | | Unit Count | 4 Count | ## Product Details - **Brand:** Walex - **Item Form:** Tablet - **Scent:** Ocean Mist - **Specific Uses For Product:** Toilet - **Material Feature:** Natural - **Item Volume:** 4 Cubic Inches - **Net Quantity:** 4 Count - **Surface Recommendation:** Plastic - **Material Type Free:** Formaldehyde Free - **Special Feature:** Concentrated, Residue Free ## Images ![Walex CMDOBG Commando Black Holding Tank Cleaner Drop-Ins, Ocean Mist Scent (1 Year Supply) - Image 1](https://m.media-amazon.com/images/I/81zggOELBeL.jpg) ![Walex CMDOBG Commando Black Holding Tank Cleaner Drop-Ins, Ocean Mist Scent (1 Year Supply) - Image 2](https://m.media-amazon.com/images/I/81tcMYmc2OL.jpg) ![Walex CMDOBG Commando Black Holding Tank Cleaner Drop-Ins, Ocean Mist Scent (1 Year Supply) - Image 3](https://m.media-amazon.com/images/I/91Ma3jT9yrL.jpg) ![Walex CMDOBG Commando Black Holding Tank Cleaner Drop-Ins, Ocean Mist Scent (1 Year Supply) - Image 4](https://m.media-amazon.com/images/I/81CROf3ltEL.jpg) ![Walex CMDOBG Commando Black Holding Tank Cleaner Drop-Ins, Ocean Mist Scent (1 Year Supply) - Image 5](https://m.media-amazon.com/images/I/91rz2-bwYeL.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ is what it means *by G***D on 11 June 2024* is what it means ### ⭐⭐⭐⭐⭐ Effectively Cleaned RV Black Tank Sensors *by M***N on 29 August 2023* Despite using tank cleaning drop-ins regularly and using the tank flush, we would consistently a 1/3 full reading immediately after emptying.
