We recently bought some Fumari Watermelon and were excited to try it. For some reason it tastes like soap? I didn't use soap to clean any part of the hookah, I just use water. We cleaned it out, tried some Tutti Fruity and it was fine ( not a strong flavor, but it was still good). Later, I mixed some Ambrosia (one of the best flavors imo), Fantasia Aurora and a small hint of watermelon.... Soapy. What do I do? It smells fine but idk.
