Things to Consider Before Buying the RV Toilet Holding Tank Treatment

Now that you have gone through our review, take a look at some of the things you should consider before buying an RV toilet treatment.

Formula

Typically, there are two types of formulas of an RV toilet treatment – liquid and drop-ins/tablets. You should consider what type of formula is compatible with your tank and what you are comfortable with.

For some users, it is easier to use liquid versions. Others prefer the drop-ins. Both the formulas have their perks. Liquids are naturally a bit more concentrated than drop-ins. However, they also cause more spilling.

Before buying, figure out what type of formula is more suitable for your purposes.

Durability

One thing that you should never compromise on is the durability of the toilet treatment. It should be able to last for a long period.

Many toilet treatments require adding of solution often. If it is as frequent as every month, then it is ideal. But if it requires you to add up the product every week or day, it is not durable enough. The best treatment will work just fine even if you apply it once a month. So, buy considering this aspect.

Container Size

Almost all the toilet treatments on our list came in different sizes and packages. All those brands considered the convenience of users while designing their products.

What size of the container you will be needing is something you should determine ahead of buying. While it is great to have a large container with an ample amount of product, you might not need all of it. However, you also don’t want to fall short of treatments. Having more is definitely better than having less.

Elements

Every toilet treatment has a few fixed elements in its formula. These elements can be categorized into two classes – natural elements and chemical elements.

Natural elements usually consist of microbes, enzymes, and bacteria. Millions of these active natural elements are present in the toilet treatments. Although natural elements are good for the environment, they typically work slower than chemical ones.

As for the chemical elements, try to avoid treatments containing harmful components like formaldehyde, pesticides, and biocides.

Supplements

Other than the main elements, some supplements are added to the formula of the toilet treatment. The functions of these supplements may vary from product to product.

The mentioned supplements are usually color, fragrance, detergent, etc. Many brands are coming with clear treatments to prevent staining. The fragrance is often used to mask the foul odor. Detergent, on the other hand, is used to speed up the cleaning.

Remember that supplements only add to the formula of a treatment. The main job is done by the base elements.

Impact on Environment

Nowadays, the impact on the environment is something every product should be liable for. Both in formula and packaging, manufacturers should factor in this consideration.

Toilet treatments with harmful chemicals, when disposed of, can prove to be extremely harmful to the septic system. Besides, overpowering fragrance can also cause sensitivity and air pollution. Finally, the packaging should be eco-friendly. As a community, we should try to minimize the use of plastic as much as we can.

Price

Of course, price is one of the most essential aspects of every product. No matter how good a product is, it should match your budget.

Packs with a lot of products often offer a better value for money. If you require a greater amount of product, it is better to take a bigger size like 1 Gallon. However, if you don’t need much, you can go with the smaller packs.

Types of RV Holding Tank Treatment

There are two types of RV holding tank treatment- liquid and drop-in/tablets.

Liquid

The liquid form of an RV toilet treatment can easily be poured directly from the container. As it does not need mixing or preparing, it works faster than the drop-ins. Because of its texture, it is also able to move things faster.

Drop-in/Tablet

Drop-ins or tablets essentially function the same way as liquids do. However, the mixing period takes more time for dissolution. The biggest benefit of a drop-in is that it prevents all forms of spilling.

You know all about RV toilet cleaners now. But it is all futile if you do not know how to use it. Here is how you should use an RV toilet treatment.
