RV black tanks can have issues with toilet paper and so there is an argument for using the expensive RV specialty toilet paper. It’s not unheard of for RVers to skip flushing their toilet paper altogether and simply bin it in the trash.
After all you spent a lot buying your RV and repairs are not cheap. But after a while of shelling out a good portion of my weekly grocery budget for a 4 pack of RV toilet paper at Walmart, I finally decided to take the plunge and do the toilet paper test that is spoken of in RV forums and Facebook groups. That is, I took a normal toilet paper square and put it in a cup of water for 15 minutes to see how well it would disintegrate compared to the specialty RV toilet paper.
To my and my husband’s surprise, the run of the mill Angel Soft
brand tested better/broke up more in 15 minutes in water than our expensive specialty RV toilet paper. We switched to Angel
Soft and haven’t looked back or had any issues with our black tank. Although at
one point in the Covid-19 toilet paper shortages we found it hard to find any…the
expensive RV toilet paper was still there waiting for us, which is good if not expensive to know should there be another run on toilet paper in the future.
Because I do not want to be responsible for your RV here is a disclaimer: This information is just what I do. If it would damage your RV please don't do this. I am just a fellow RVer like you trying to figure this stuff out and not a chemist or a professional anything to know what could or could not hurt your RV.
