Monoethanolamine for RVs?

I read an article on cleaning the RV roofing. They used this word, (Monoethalomine); good for the removal of tree sap and berry stains. This word does not exist. Would you know the correct spelling or what this product actually is? Barbara (Alpharetta, GA)

Barbara, Monoethanolamine (MEA), is a real word and it is produced by combining ethylene oxide with aqueous ammonia. The reaction also produces diethanolamine and triethanolamine. The ratio of the products can be controlled by changing the stoichiometry of the reactants. Note that this reaction is exothermic and that controls are needed to prevent a runaway reaction.

MEA is used in aqueous solutions for scrubbing certain acidic gases or deposits. It is used as feedstock in the production of detergents, emulsifiers, polishes, pharmaceuticals, corrosion inhibitors, chemical intermediates. For example, reacting ethanolamine with ammonia gives the commonly used chelating agent, ethylenediamine.

So that should clear up any confusion you may have! Actually, now I’m even confused! The bottom line, it’s an organic cleaning compound that will not harm EPDM rubber roofs on RVs and is good at removing the harshest of stains, bird droppings and tree sap. It’s usually used in the production of cleaning agents aimed directly at those stains. Here’s what it looks like chemically:

 And just so you don’t think I’m that smart....I found this info on Wikipedia...
