I live in "Canada's Desert" and it is very dry here. And currently on fire.

I ran my compressor through two water separators just to try and reduce the amount of moisture getting into the abrasive. The air lines were also specially designed to reduce the amount of water introduced into the lines.

I blast on my paved driveway, and sweep up the abrasive and sift it through a medium-size-hole vegetable strainer into a bucket, and then pout it through a medium-fine-size hole vegetable strainer (it's really only slightly-finer than the other one) into the pot. This removes all the non-abrasive as well as whatever might clog the tip.

If I skip the smaller-hole strainer, I get more clogs. But it never clogged with wet abrasive.

I figured I would try re-using the abrasive as long as possible and see what it did. No complaints.
