I really appreciate these. Read the directions. Use as it says although I usually put the pod in the toilet, add HOT water so the stupid skin from the pod dissolves. And then fill the black tank up. The pod skins are disgusting and I don’t use pods for anything but this brand only comes in pod form. It works. Bubbled up. Gets the chunks out. ### ⭐⭐⭐⭐⭐ Effectively Cleaned RV Black Tank Sensors *by on Reviewed in Canada 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. 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. ## Frequently Bought Together - Walex Commando RV Black Holding Tank & Sensor Cleaner - Eliminates Waste & Paper Buildup, Restores Sensor Function, Lubricates Valves & Seals, Advanced Enzyme Formula; Dissolvable Packets, 4 Count - Walex Elemonate Grey Water Tank Deodorizer & Freshener - Freshens Sink & Drain Lines, Rapid Dissolving Drop-In Tablets, Ideal for RV's, Boats & Homes, Easy to Use - Fresh Lemon Scent, 5 Pack - Camco TST MAX RV Toilet Treatment Drop-INs - Control Unwanted Odors & Break Down Waste and Tissue - Safe Septic Tank Treatment - Orange Scent, 30-Pack (41183) --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.is/products/649753357-walex-cmdobg-commando-black-holding-tank-cleaner-drop-ins-ocean](https://www.desertcart.is/products/649753357-walex-cmdobg-commando-black-holding-tank-cleaner-drop-ins-ocean) --- *Product available on Desertcart Iceland* *Store origin: IS* *Last updated: 2026-06-22*
