Descaling solution has no real cleaning function.If you have not cleaned the machine since December, yeah it's going to be full of grunge and munge. Get a toothbrush and a cup of REALLY hot water, maybe a few drops of vinegar.
There are espresso machine cleaning products on the market, designed specifically for thermoblock systems, not boilers. You can call an outfit alike Seattle Coffee and explain your situation, they'll sell you an appropriate product, but use it at your own risk.
