True it does work. But......use caution when using it. The product comes out very cold and will cause some plastics to disintegrate after use. I am not saying it will happen over time, but it can happen right after using it.
Also, always allow it to completely evaporate after use and allow it to sit for at least 30 minutes to let the plastic get back to room temperature. I learned this the hard way when I first started to use this product 20 years ago.
A bast of air as Craig said works well and I feel it should be the first means of attack.
