Before you take your next RV trip, make sure the black and gray tanks are properly treated
There are so many things we love about the RVing lifestyle. Satisfying that traveling bone. Meeting new friends. And seeing the places that you used to only read about in magazines. There are few things better in life than gathering underneath the stars in the evening, and waking up to a spectacular morning in a new place, greeted by the scent of freshly cut grass or desert sage — and realizing there’s nothing on your agenda for that day.
But the one thing that can suck the joy out of every RV trip is holding-tank odor. It’s bad enough when it arrives like a malevolent ghost whenever you flush the toilet — but when it permeates the interior, you’ll begin to notice fewer and fewer accepted invitations to your social events. Maintaining a clean holding tank is not unlike taking care of your health — it’s a lot easier to maintain good practices every day than to make up for neglect later on. Most holding-tank odors are the result of improper and/or infrequent maintenance, so proper holding-tank treatment dosage along with the correct dumping practices are key to olfactory bliss.
There are dozens of holding-tank treatments on the market today, which can make choosing the right one for your needs daunting. The most important considerations are whether you prefer a natural/biodegradable product, or a chemical-based product that may contain formaldehyde, dyes and perfumes – an important consideration if you are sensitive to such additives. From there, it’s simply a matter of the delivery method: liquid, powder, or the most recent development, the drop-in (aka toss-in).
Because the choice of a holding-tank product is a very personal one, we’re presenting this guide to some of the most popular holding-tank products, in each company’s own words. Keep in mind that we can’t possibly cover every product each company makes, but a visit to any of these websites will reveal a multitude of choices.
TST: When you’re shopping for a holding-tank treatment, odds are that good value and long-lasting odor control are at the top of your list. Lucky for you, Camco’s original TST RV toilet treatment offers these benefits and more. Just four ounces treats a 40-gallon holding tank and controls odor for up to seven days — during any season. The product also breaks down waste and tissue, lubricates valves and cleans sensors. And, environmentally sensitive campers will appreciate that TST contains no formaldehyde and is 100 percent biodegradable. Retail cost: $6-$7 (32-ounce liquid).
Grey Water Odor Control: When we think about holding-tank odor, it’s usually the black tank that comes to mind. But the truth is, the gray tank can also play an offending role. Months (or years) of food particles and grease can eventually build up, causing unpleasant smells to rise from drains throughout the motorhome. Camco’s Grey Water Odor Control is designed specifically to combat these issues by removing grease buildup in the gray-water tank, sink and shower drain lines. Just four ounces treats 40 gallons, and the end result is a fresh, lemon scent. Retail cost: $8-$10 for 64-ounce liquid.

Travel Jon: Century Chemical not only makes holding-tank products for RVs, but for marine, aviation, charter bus and portable applications as well, so it’s safe to say they know a thing or two about odor control. The company’s Travel Jon product has a familiar blue color that is biodegradable and contains no formaldehyde. The highly concentrated formula (only 2 ounces per charge) helps break down waste and tissue, and the detergent component helps keep the holding tank clean. Retail cost: $14-$18 (128-ounce liquid); $5.99-$7.99 (dry). Other products: Travel Jon Waste Digester, Travel Jon Blue Max toss-in packets. Century Chemical Corp., 800-348-3505, www.centurychemical.com
Dometic is practically a household name, but it wasn’t until a couple of years ago that the RV giant introduced its own line of holding-tank products. One of its most popular offerings is its Premium Holding Tank Treatment, available in liquid and dry formulas. Aside from long-lasting, formaldehyde-free odor control (even in hot weather), the product’s additives break down waste and help tanks rinse cleaner during pump out. Retail cost: 32-ounce liquid, $10.94; 24-pack drop-ins, $24.99. Other products: 3 ’N 1 Bowl Cleaner and Tank Treatment, Clean ’N Green holding-tank treatment, Gray Water Tank Treatment.

Eco-Save Dry: Looking for an alternative holding-tank treatment product? Eco-Save Dry could be it. Eco-Save Dry is a bacteria/enzyme-based product that works in both black- and gray-water holding tanks, and contains no perfume or surfactants — just friendly bacteria that actually enhances the digestion of waste in septic systems. The environmentally safe, nonstaining product does not clean the holding tanks, but it does reduce solids and control odor. Plus, it is very economical — an 8-ounce jar of the product treats 30-35 tanks (not gallons) of waste. Retail cost: $25 (8-ounce jar). Other products: Eco-Save Original Formula (liquid), Eco-Save Fragrance Enhanced, Eco-Save Concentrate. Eco-Save products, 800-950-9666, www.eco-save.com
Kronen Premium Holding Tank Treatment: Why use chemicals that actually preserve black water, when you can break it down and eradicate it? That’s the question ProPack Packaging asks when referring to its Kronen product. Using a potent combination of naturally occurring microorganisms that are specifically engineered to break down organic materials, Kronen reduces the holding-tank contents to liquid and leaves behind a subtle, herbal scent. Kronen liquid is available in a 32-ounce size, a half-gallon jug, and a six-pack of 4-ounce single-use bottles. Retail cost: $32.99 for a 128-ounce jug. Also available in a pack of 10 Drop In’s for $13.99. Other products: Kronen Toilet Bowl Cleaner. ProPack Packaging,
T-5: If you believe that experience counts, consider that the Monochem name has been synonymous with holding-tank products for the RV, commercial motor coach, aviation and marine industries for more than 55 years. Even if you haven’t used it, you’ve probably already experienced its benefits; this blue powder toilet chemical has been used to neutralize waste odors in recirculating and portable toilets since the company’s inception. The premeasured, 2.25-ounce, moisture-resistant foil packets are simple to use — just pour the contents of one packet into the toilet, and T-5 will immediately begin combating odor-causing bacteria. Retail cost: $15.95 for a box of six 2-ounce packets. Other products: T-5 NF (non-formaldehyde), Aqua-Toss toss-ins, Dyna-Bact toss-ins, L-10 liquid toilet chemical, L-10 NF RTU liquid toilet chemical, T-5 super concentrated liquid.

Billed as the No. 1-selling holding-tank deodorant of all time, Aqua-Kem liquefies waste and breaks down tissue fast to prevent clogs, while powerful detergents clean tank walls and drain lines. Aqua-Kem works around the clock in all weather conditions, and although it contains formaldehyde, it is biodegradable and environmentally safe when disposed of properly.

Eco-Smart, Eco-Smart Free & Clear: A kinder, gentler way to treat holding tanks. Original Eco-Smart uses a nonstaining, formaldehyde-free formula that quickly breaks down and liquefies waste and toilet tissue and provides odor control, while a detergent additive keeps tanks clean. Orange Eco-Smart is also nonstaining and uses an enzyme formula with a natural enzymatic deodorizer, while Eco-Smart Free & Clear offers the same benefits as the above but is fragrance-, dye- and formaldehyde-free and is 100 percent biodegradable. Eco-Smart products are available in liquid or toss-in form. Retail Cost: $16 for Eco-Smart Free & Clear 36-ounce liquid, $9-$12 for pack of 12 toss-ins.
