I agree that the hands on approach is the best. You learn by doing, especially in the sanitation field (These people spent all night cleaning, the last thing they want to do is sit down in front of a screen in a dark room to listen to someone just talk [to encourage them to sleep]). Go out onto the production floor and have them simulate like what Magenta-Majors is suggesting. However, I don't correct as they go. I have the sanitor complete the process and then ask the group ok what did he/she do wrong? Nothing works better then letting them banter and they can't wait to hop on one another. What I think has also helped is taking pictures as they go. I transform my SSOP's into a Pictorial Work Instruction. Has the same function but with pictures.
All good points. Having them all contribute to the process of working out what is best helps. If you run the training as a hands-on session with them making suggestions on how to do it better, you may find more effective ways to clean and sanitize. After all, they do it every night, so they are kind of experts on what does not work well. And if they can take ownership of the process, they will be more apt to follow it.
The SSOPs in picture form is a great idea as well. Pictures are really worth 1,000 words.
Injecting some humor is always good. People remember facts better if an emotion is attached to it, and you would like to have fun attached to any work activity. Making up a crazy certificate to give them after the training may give them a smile and evoke some pride. Maybe something about being Crazy about Cleaning? Anything to relieve the boredom and make it a more human experience helps.
Just an additional example. There's nothing more boring than safety talks, so I inject some funny pictures in my talks just to keep people awake and make them feel more happy. I made one for the end of the Lockout/Tagout presentation (a really boring topic), showing a picture of He-Man holding a lock saying that they control the power. It always gets a laugh.
I'm sure you can come up with something that will work.
