Keep Your RV Holding Tanks Clean & Flowing Properly

Over time, waste, paper, grease, soap residue, and other debris can build up inside your RV's black and grey tanks. Regular dumping doesn't always remove everything left behind, allowing buildup to accumulate on tank walls, around sensors, and near drain areas. This can contribute to unpleasant odors, slow drainage, inaccurate tank readings, and other holding tank problems that make using your RV less comfortable.


Our technicians provide thorough RV black and grey tank cleaning designed to remove accumulated buildup and help restore proper tank performance. We evaluate the system, clean the holding tanks, and look for signs of drainage or tank-related problems that may need additional attention. With mobile RV tank cleaning in Surprise, AZ, Holt Brothers comes directly to accessible RV parks, campgrounds, homes, and other service locations so you can maintain your holding tanks without taking your RV to a traditional repair facility.

RV Black & Grey Tank Cleaning FAQs

  • WHY DOES MY RV BLACK TANK STILL SMELL AFTER I EMPTY IT?

    Odors can remain when waste, paper, or other material has built up inside the tank even after the tank has been emptied. Other holding tank or plumbing issues can also contribute to odors, so persistent smells may require further inspection.

  • WHY DOES MY RV BLACK TANK SENSOR STILL SAY FULL AFTER DUMPING?

    Tank sensors can provide inaccurate readings when waste or residue collects around the sensors inside the tank. Cleaning the tank may help when buildup is interfering with the sensor readings, although sensor or electrical problems can also cause inaccurate readings.

  • WHAT IS THE DIFFERENCE BETWEEN RV BLACK AND GREY TANKS?

    The black tank generally holds waste from the RV toilet, while the grey tank collects wastewater from fixtures such as sinks and showers. Both tanks can accumulate residue and buildup over time.

  • HOW OFTEN SHOULD RV BLACK AND GREY TANKS BE CLEANED?

    There isn't one cleaning schedule that works for every RV. How frequently your tanks need attention depends on how often the RV is used, how the tanks are maintained, what enters the tanks, and whether you're experiencing odors, drainage issues, or inaccurate sensor readings.

  • DOES EMPTYING MY RV TANK COMPLETELY CLEAN IT?

    Not necessarily. Emptying removes the material that drains from the tank, but residue and buildup can remain on tank surfaces and around sensors. A more thorough cleaning may be helpful when normal dumping isn't resolving odors, sensor problems, or buildup.

  • CAN PROFESSIONAL TANK CLEANING HELP WITH INCORRECT SENSOR READINGS?

    It can help when buildup on or around the sensors is causing inaccurate readings. However, incorrect readings can also result from problems with the sensors or electrical system, so cleaning isn't guaranteed to correct every sensor issue.

  • CAN YOU CLEAN MY RV HOLDING TANKS AT MY LOCATION?

    Holt Brothers provides mobile RV black and grey tank cleaning in Surprise, AZ at appropriate accessible service locations. Contact us with your RV and location information so we can determine whether mobile tank cleaning can be performed there.

  • CAN YOU HELP IF MY RV TANK ISN'T DRAINING PROPERLY?

    Yes. Poor drainage may involve buildup, a valve issue, a blockage, or another part of the holding tank or plumbing system. We can evaluate the problem and determine whether cleaning or RV plumbing repair is the appropriate next step.
