Use a Fleet enema bottle. Empty the contents, wash out with hot water. Wipe off lubricated tip thoroughly with a dry paper towel and wash with hot water. Do not use any detergent! Fill up the bottle with room temp water poured through a coffee filter. Preferable to boil water in glass container and let cool.
Add up to 1/2 teaspoon of Lugol's. After a few enemas, it can be increased to one teaspoon. Avoid spilling. It stains.
To lubricate tip use only olive oil, butter, vitamin E gel. Do not use commercial chemical lubricants.
Do the enema. Hold it in for 5 to 15 minutes or as long as you can. Initially you may only be able to hold it for a few minutes. Expect loads of mucus, gel, trash, undigested food and several movements within hours as mucus keeps coming out. If you're mucus loaded-up, repeat enema daily for 2, 3, or 4 days. Then once a week for 4 weeks until mucus/trash-free. Maintenance, one enema a month.
