After following the above excellent advice on reconditioning the stone, it's a good idea to saturate and maintain it to prevent it from clogging again in the future. Let the stone air dry thoroughly after cleaning/degreasing. Saturate it with oil as a first step. I personally would recommend honing oil. I like Lansky because it smells nice. Some say honing oil is a waste of money and you should just use mineral oil. Actually, a bottle of Lansky oil only costs a few dollars and lasts a very long time. So you're talking about saving pennies. Plus there is the problem that Coonskinner alluded to in that a random oil may not be the right weight. Honing oil is formulated at the right weight to penetrate the stone and float swarf without gumming the stone up too quickly.
You can saturate the stone by pouring oil on the surface and letting it soak into the stone. Then pour some more (don't let it spill over the top, just pour enough to pool on the surface). Repeat until it won't absorb any more oil. When you sharpen, start with putting a few drops on the surface of the stone, enough to just have a sheen on top. As swarf develops from sharpening, wipe it off with a cloth. When finished, wipe all swarf from the surface with a rag and store the stone in an airtight container like a Ziploc bag so that it doesn't dry out. That will keep your stone in good shape and prevent it from clogging up. When you need to use it again, it should still be saturated and will only need a few drops to make a sheen on the surface again.
