I am not sure if there are negatives but I use plain rubbing alcohol. A ski racing friend said he started using it because he could not travel with cleaner, just waxes and tools and would buy it locally. Its works fine, evaporates quick to dry fast, is super cheap and readily available. I have also used clear alcohol hand cleaner which is loaded with alcohol. As a side note both products work well taking off pine pitch if it lands on your car. Try it if you run low of swix cleaner and see for yourself. It works fine.
