Not only does Cottonelle toilet paper dissolve easily and prevent plumbing issues down the line, but it is also soft, absorbent, and strong. Below are the essential factors that make Cottonelle toilet paper clog-free and septic-safe;

1. Dissolvability

This feature is one of the most important as long as Cottonelle toilet paper is concerned. It can dissolve readily enough for several septic systems to handle, which is why it is labeled biodegradable.

If you want to see if it is genuinely dissolvable, you can mix a few sheets into a big cup of water and observe how quickly it dissolves.

2. Free from Chlorine

Septic tanks house anaerobic bacteria, which decompose waste. Using chemicals such as bleach, solvents, and some cleaning agencies will alter the delicate balance in the septic tank, thus affecting waste decomposition.

However, with chlorine-free Cottonelle toilet paper, there is little or no chance of such substances leaching into your septic system.

Even though Cottonelle can dissolve quickly, it has a high enough wet power to complete the job without shredding and a lower wet strength than an average toilet paper to dissolve immediately after being flushed.

5. Softness

Without being asked! No one is a fan of rough or abrasive toilet paper. So, Cottonelle is the best septic-safe toilet paper, soft and enjoyable for daily use, yet thick enough to dissolve quickly.

Why Is Cottonelle Toilet Paper Best for Septic Systems?

Note that whenever toilet paper enters the toilet, it moves into the septic tank, sinking the tank’s solids into the bottom, where it breaks down into sludge.

This sludge buildup can subsequently require more frequent cleanouts, thus explaining why getting toilet paper that won’t add to this buildup is very important.

There are many reasons you must get perfect and completely septic-safe toilet paper, knowing that it won’t cause any harm to your septic system.
