## Questions & Answers

**Q: What makes Happy Campers Extreme Cleaner different from regular RV tank treatments?**
A: Extreme Cleaner is an industrial-strength cleaner formulated to break down stubborn sludge, hardened waste, and residue that builds up over time. It’s designed for deep cleaning and restoring holding tanks, not just routine maintenance.

**Q: Can I use Extreme Cleaner in both black and gray tanks?**
A: Yes! Happy Campers Extreme Cleaner is safe and effective for both black and gray holding tanks. It restores sensors, removes buildup, and helps eliminate odors in both types of tanks.

**Q: How often should I use Extreme Cleaner?**
A: Most RVers use it as a periodic reset—for example, once a season, before long-term storage, or when tank sensors stop working properly. It is not meant for daily use; instead, think of it as a powerful deep clean to return holding tanks to new.

**Q: Will Extreme Cleaner help fix my tank sensors?**
A: If your sensors are misreading because of sludge or waste buildup, Extreme Cleaner can help remomve the debris and restore accurate readings. However, if your sensors are physically damaged, corroded, or broken, no cleaner will repair them.

**Q: What if I use the Extreme Cleaner and my sensors still aren't reading correctly?**
A: When used as directed it leaves tanks and sensors clean. If sensors are not working after using the Extreme it is typically because the tanks were not flushed with fresh water after use. Try rinsing again. If issue reamains - sensors may be broken.
