Why Is Regular RV Tank Cleaning - by a Professional - So Important?
Short term answer: You get bad smells, inaccurate sensors, slow drains, and all that extra weight
Long term answer: Harmful deposits are harder to remove (read: "More expensive") when allowed to remain over time.

Unconvinced? Then take a look at what's lurking in your tanks:
More often than not, your RV’s black and gray tanks are out of sight and out of mind. Out of mind, that is, until something starts to smell wrong, back up, or misbehave. Beneath the surface, a lot can accumulate—some of it nasty, some of it downright weird. Here’s a breakdown of the most common troublemakers hiding inside your tanks beginning with the most stubborn culprit: Struvite.
Struvite
This mineral compound is notorious for silently accumulating inside black and gray tanks, where it binds to surfaces, forming dense, rock-like layers. Struvite buildup doesn’t just stick around — it interferes with tank readings, contributes to persistent foul odors, and puts unnecessary stress on your system due to the added mass. Traditional tank draining or flushing tools like rinse sprayers and manual wands aren’t enough to dislodge it.
As struvite sets, it hardens significantly—sometimes coating tank interiors, valve areas, and plumbing with layers that can exceed half an inch in thickness. Over time, this can deform tanks due to the extra weight and restrict water flow entirely.
Struvite must be specifically targeted. Dumping your tanks won’t get rid of it, nor will the use of built-in tank rinsers. It takes precision techniques like professional hydro-jetting to loosen and dismantle the mineral crust so it can be fully flushed from the system.
Mold Colonies
You’ll often find dark, chunky mold thriving on bits of food and grease in your gray tank. It settles into corners and grows fast—especially when your RV sits unused for a while. Most gray tanks don’t even have a way to flush it out. And it smells terrible.
Unwanted Guests
Insects (and sometimes worse) can end up living in your tank. Larvae and other creatures find their way up from sewer connections or sneak in through venting. It’s not common, but once you’ve heard the stories, you’ll never forget them.
The Goo (Sludge)
This thick, tan gunk forms from undissolved TP, chemical residues, and certain additives. It pools at the bottom and never fully drains, even when you think your tank is empty. It’s sticky, heavy, and clogs everything from the bottom up. Regardless of what you might have heard, standard flush systems cannot get rid of it.
Grease Film (Soap Scum)
Sinks and showers send soapy residues (along with tons of hair and sloughed-off skin) into the gray tank, where it settles and hardens into a slimy buildup. The more it builds up, the slower your tank drains—and the heavier your RV becomes.
