On our drinking water treatment project in
Sudan, we’ve been using vegetable oil to release the concrete water
filters from the steel molds. It is readily available and compatible with
drinking water (see link). www.enviro-stewards.com/website_sudan.pdf

diesel commonly used as a release agent for concrete forms. Does anyone
know of a possible substitute that won't be prohibitively expensive? Judy Kennedy |
