I'm not having alot of luck either. I bought the jumbo size salts from Saltworks. The first time I used bath dye, sprayed them let them dry add more fragrance and let them dry. I couldn't smell it when I put it in the warmer. The 2nd batch I add alot more fragrance, it never competely dried, it smelled nice on the kitchen counter, but I really didn't get a great throw in warmer. I was using a strong fo. Now I have a couple of small batches of scented salt, I put them in warmer and just pour more fragrance over the top of them, only then can I really smell it.
