Actually, in that part that tends to get dirty. I found a goods called "Toilet crevice dirt prevention sheet" at the 100-yen shop CAN DO. I tried it.
A sheet that prevents dirt from entering by sticking it in the gap between the front part of the toilet bowl and the floor. It has adhesive on the back side and can be bent and stuck firmly. There were some wrinkles when pasting, but there is no problem with the appearance. If it gets dirty, you can wash it by hand with lukewarm water and use it repeatedly. The approximate size is 80 x 540 mm. I couldn't cover all the gaps, but it seems to be easier to clean in the future.
The back side is an adhesive surface
First, clean the part to be pasted,
The sheet with the film on the back side peeled off,
The gap between the toilet bowl and the floor is difficult to remove once dust gets in. It can cause darkening and unpleasant odors, so why not use a sheet like this to prevent it? The price is of course 108 yen (tax included) each.
