How to clean k-rendered wall?

Hoping someone can advise.....
I had a garden wall built around 18 months ago and the front of the wall (from the top to the ground) was k-rendered. With the wall touching the ground, I find that when it rains, dirt from the ground splashes up on the wall.

I have attached a couple of photos of my wall showing the dirt.

Can anyone advise how best I can clean this, and is there anything I can put on the wall to minimise the amount of dirt sticking to the wall?

It not only cleans but the chemicals in it prohibit future growth. It’s not perfect, can take time, but it takes a lot of the scrubbing and very harsh chemicals out of the cleaning process.
God knows how the thin coat lads do it especially in the winter I’m no expert but I think it takes two -three days to go off proper so you have to be John kettley!
