I think one of the most valuable tricks I was taught was that items do not need to be immersed in StarSan to be sanitized, but only coated. So, I put about 1/4tsp of StarSan in 24oz of distilled water in a garden sprayer and I'm good for quite a while conveniently sanitizing items as needed from a garden sprayer. Saves a TON of money on sanitizer.
