water in the intake

I've seen an old timer mechanic do that trick to decarbonize big block chevrolets. He sprayed with a hose on about 1/3 and held his thumb over the end of the hose. He sprayed intermittently and didn't use very much water, but I saw steam come out the exhaust pipe. The car idled and ran much better after this. He did remind me not to use too much water though.
