RV Toilet Paper Tablets Buyers Guide

Benefits of using RV Toilet Paper Tablets

There are several benefits of using RV toilet paper tablets, and these apply whether they come in tablet or powder form.

The primary reason is that they can break down and liquefy both solid waste and toilet paper. This makes it easier for the black or holding tank to be emptied. The tablets also prevent lumps of solid waste and paper becoming clumped together which can cause difficulties in emptying the tank, and even lead to blockage.

By reducing the solid waste and paper, the tablets also help to reduce the chances of paper causing a blockage in any of the water or drainage lines. Some also have detergent in their formula which cleans these lines and reduces the chances of blockages even more.

Foul odors are an undesirable aspect of many toilets and are a particular problem when it comes to RV toilets, where the waste remains in the holding tank. Thankfully, most RV toilet paper tabs can help eliminate these horrible odors to keep your RV smelling fresh and clean.

Things to Consider Before Buying Toilet Paper Tablets

Cost

There can be big differences in the cost of toilet paper tablets and this can be magnified based on how many tablets you get with each purchase. A low price isn’t much good if you must make multiple purchases because the number of tablets supplied each time is low.

Odor Elimination

Not every tablet or powder eliminates odors. Some are designed purely for their cleaning benefits, so always check if you want a tablet that will help keep your RV smelling nice.

Tablet or Powder

Although we are discussing toilet paper tablets, many of the products come in powder form. A powder is no less effective, but if you are concerned about having to measure out an amount then tablets might be best for you.

Eco-Friendly

Although none of the products we have reviewed contain any dangerous chemicals such as formaldehyde, some may have ingredients which are not regarded as eco-friendly. If the environment is something you care deeply about, then there are several RV toilet paper tablets and powders which are biodegradable and thus not harmful to the environment.
