How do I clean the FloraCaps (caps)?

SURFACE CLEANING DIRECTIONS FOR USE: Mix 37ml of BioSafe Systems GreenClean Acid Cleaner per gallon of fresh water. Allow to soak for 1-2 hours followed with a clean water rinse using a pressure washer or hose sprayer/nozzle. Higher rates are recommended for heavily soiled surfaces. After rinsing, use SaniDate 5.0 Sanitizer/Disinfectant according to label directions to disinfect hard surfaces and equipment. Or you can put them in a dishwasher.
