I use this one: APEL Silicone Mold Release Spray (14.4 oz) Release Agent Aerosol Spray https://www.amazon.com/dp/B085CBSS5Y/ref=cm_sw_r_cp_apip_UFHjKTn1eRMTa

I spray it and let it dry for about an hour. Never had an issue with it making my resin cloudy and my resin always pops out beautifully when cured!
