If I couldn't have real grass, I'd have paving or gravel. Artificial grass is just so bad for the environment, in manufacture, use, disposal - and disintegration - that I, too, think it should be banned.
A relative has it - and keeps a special workshop vacuum to clean it - along with her patio and driveway - ridiculous!
Friend of a dd had a small and very narrow urban garden that didn’t get nearly enough sun for grass to do well - she also had two very small children and wanted a forgiving surface for them to play on. Paving or gravel wouldn’t have answered, and decking can be notoriously slippery.
It wasn’t at all a question of mowing being too much of a bother.
I don’t care for artificial grass myself, but it’s all very well to be sanctimonious about it if you have a large or fair sized, sunny enough garden - lots of people don’t. Or if you don’t have small children to think of.
OP, wouldn’t a good soaking with a sprinkler wash it through?
