Cleaning concrete garage floors without a mess.

So my concrete floor cracks have filled up over the two years of living here. One answer is water, the other answer is air. Both are a little messy, the water creates mud and a slick surface so I can bust my ass. 

The compressed air gets it out, but then I have a ton of dust in the air (which resettles on everything I don’t want it to), it also blows the big chunks out, which then have to be swept with a smaller broom into a dust pan to avoid dumping more crap back into the cracks. 

Also trying to do this with the garage door closed, otherwise more crap blows in. Looking for creative ways to make this less work. Or do I just need to face it?

Shop vac with crevice attachment combined with compressed air?

In reply to Stefan :

I guess that’s not a bad idea. It’s currently the only idea here. So I’ll try it. 

My shop vac does a pretty good job of getting most of the crap out all by itself. 

Sweeping compound.

Seconded. Used to use it in the hangars at the flight test facility. Worked really well.

Just have to vacuum out all the crevices.

You can also use pine sawdust and parafin.
