Is it possible to clean my pea gravel already laid down

Dee, just water it as if it was grass. The dirt will run through the weed barrier with the water. A few good rainstorms will help, too.

I appreciate all your responses.. but it's not about water going through or cleaning off the top layer of dirt.( It's been down for a whole year through numerous rainstorms and tons of snow. ) All the dirt is still trapped just below the surface...It's the dirt that cannot pass through the weed barrier not the water, so as soon as the stones are even slightly disturbed the dirt resurfaces as either mud or dust. That dirt is forever trapped...This is our Patio not a path or bedding fill, so it's very inconvenient. We will probably have to lay patio blocks in the dining area.

I know this is four years later ... but I have the exact problem; we had our whole yard around a new patio filled with pea gravel — and after it was put down I discovered how filthy it truly was and it doesn’t matter how much I spray it, the weed barrier cloth traps in the clay dust and silt. It’s horrific because my kids play on it and are coated in clay ans worse their lungs are exposed to silica! After thousands of dollars on this landscape project — I’m having to figure out how to remove the barrier so the dangerous dust can get into t he earth and out of my backyard. How did you ever solve your problem??

We have been useing gravel for our patio area an a place for our puppy to go out on, an we made the mistake of buying "P" gravel, instead of lime stone, lime stone seems to be cleaner,
