My understanding is that those wipe won't dissolve. We have a septic system at two of our homes and they shouldn't be used.
In the motorhome, we have a macerator toilet and I wouldn't think that would be good for our toilet. We also have the option to use our macerator/hose when it's time to empty the tanks, again, not good for a macerator.
I just recently bought TP at Walmart. The 'Coleman' brand of TP for 4 small rolls was $3.99 a pack. We went over to the grocery section and found the cheap Walmart TP and was .89 a four pack. So, I bought several as it said on the pack it was septic safe.
When I got back to the motorhome I compared our .89 Walmart TP to our Camping World TP, put them in the sink, ran water on them and they dissolved exactly the same. So, it's Walmart TP at .89 a pack from now on! LOL!
Safe travels,
