The j-pouch "backsplash" is one of my every day annoyances. I find I'm constantly cleaning the toilet seat and bowl. When I visit friends and family, I always check for the dreaded splash and then clean the toilet if necessary (wiping with TP if I'm at someone else's home), as I won't leave a mess like that for friends and family to deal with.
However, I have over the years come up with a couple of tricks that help keep toilet clean at home. After I flushing, I spray the bowl with Tilex Fresh Shower or a similar product. I actually prefer the Method Daily Shower spray ( https://well.ca/products/metho...wer-spray_33336.html ) as it smells less like a cleaning product and is supposed to be more environmentally friendly. This seems to keep the backsplash from sticking to the bowl and it rinses away more easily when you flush the next time, hence cutting down on the number of times you actually have to get in and scrub the bowl.
If I'm at someone else's place, I will also lay a row of toilet paper down on the back of the seat and fold it under just slightly. This helps to catch any mess.
I'm also lucky enough to still have an older toilet in my condo. Although the newer low flow toilets use as much as 3x less water, I find the flush is not powerful enough to rinse away the mess. I loathe the low flow toilets my parents have at their home for that reason alone. Unfortunately I will probably have to replace my good old power flush in the near future as my condo corp may start mandating low flow toilets to cut down on water consumption. I'm generally an environmentalist first - this is the one area where I don't feel guilty slacking!
