The Problem

Cleaning an RV or boat toilet without destroying the beneficial bacteria inside your black water holding tank is a difficult task. Household toilet bowl cleaners rely on bleach or caustic chemicals which can get your toilet bowl clean, but at the cost of destroying the necessary bacteria inside your tank that help break down waste and keep odors at bay. You need a product that is going to make your toilets sparkle while enhancing the bacterial breakdown inside your holding tank.

The Solution

Unique RV Toilet Cleaner + Holding Tank Enhancer uses an advanced blend of bacteria and enzymes that contains no caustic chemicals like bleach to remove even the toughest toilet bowl stains while enhancing the bacterial breakdown inside your holding tank. So you can rest easy knowing your toilets are sparkling clean and your holding tank is safe from backups, clogs, or odors.

The Science

Traditional household cleaners use the power of caustic chemicals like bleach to clean your toilets. This bleach then works its way into your holding tank and utterly destroys all the beneficial bacteria that keep your tank odor-free and flowing. This leaves you at an extreme risk for foul odors, annoying backups, and costly clogs. RV Toilet Cleaner + Holding Tank Enhancer’s powerful cleaning formula is infused with a bacteria / enzyme blend that cuts through tough stains and obliterates foul toilet odors. Better yet, the same bacteria / enzyme blend that leaves your toilets sparkling clean, also helps to eliminate odors and prevent backups inside your holding tank.

*RV Toilet Cleaner + Holding Tank Enhancer is NOT a tank treatment. You still have to use a routine tank treatment, like RV Digest-It.

Question: How much toilet cleaner should I add to the bowl?

In general, you should use enough toilet cleaner to completely coat the inside surfaces of your toilet bowl after the product has been spread around with a toilet-cleaning brush or sponge. Most likely, this will require a generous amount of product—at least a couple of ounces. You may need to reapply in order to remove especially tough stains.

Unique Method Approved

Cleaning your toilet bowl with bleach or chemicals is a sure way to kill the beneficial bacteria inside your black tank, and will increase odors and your chances of clogs. The Unique Method advises against the use of these problematic cleaners. Unique RV Toilet Cleaner will make your bowl sparkle using tank-safe bacteria and enzymes.

The Unique Method is a proven treatment process that will help you effectively prevent clogs, odors, and misreading sensor probes and ensure your holding tanks remain hassle-free.
