Toilet

Noticed that toilet seat covers are invented for hygenic purposes. However, why there isn't any covers for the lid? People assume the lid is clean? 

At home, I always have to clean the toilet lid as there is always some of the urine got onto the lid. This is rather frustrating as I always  have to clean it. The reason for this frustration is sometimes I need to lean back onto the lid to be able 💩 out. Imagine you lean on the lid with urine remnants, you'd be actually using your top to wipe it. 🤮. 

Why haven't anyone thought of this? This is just my opinion, my say.
