How often should you deep clean your RV’s black and gray tanks? 🚌🚽
Even if you’re doing everything right, waste, grease, and soap scum can build up over time leading to odors, clogs, and misreading sensors.
How to deep clean your RV black tank:
1️⃣ Close your black tank valve.
2️⃣ Fill your black tank completely with fresh water.
3️⃣ Add Clean-It through your RV toilet (one bottle per 40 gallons).
4️⃣ Let it soak for 48–72 hours to break down leftover waste and buildup.
5️⃣ Dump your tank, then thoroughly rinse by filling and dumping again.
How to deep clean your RV gray tank:
