The invention relates to a hole opening method for a foaming sponge product. The method comprises the following steps of immersing a sponge semi-finished product meeting the process requirements intoa molten composite salt bath in a solid-liquid mixing state, circulating the salt bath and destroying the thin-wall tissue of the sponge through the solid crystalline salt, and achieving the effect ofcompletely opening the hole in a short time; placing the foamed sponge which has been opened in the warm water, repeatedly soaking and flushing with a water gun, and dissolving and washing the crystallized salt; and placing the finished product in a hot air oven for dehydration treatment. The hole opening method for the foaming sponge product has the advantages of high hole opening rate, low production cost, good safety and environmental protection.
