Ok. found a kitmaker for syno and did conversion. And rinsed prop with 200-300ml water 3 times but the prop is dry and taste like chemical or drugs. Isn't it supposed to be tasteless?? Hope is rinsed it enough. Anyway to tell? Maybe I could buy some ph strips? Also the kitmake sent me NAOH it appears- nothing special. Only 50ml of oil and A 50 ml bottle to transfer 5 carts to?? Don't know whats up with that either. THanks
