Palm With Scale

I think I have an Africa palm, which I re-potted after 3 or 4 years (about 3 or 4 years ago). I keep it on my front porch where it gets no direct sunlight and in the winter I keep it in a spare shower, also diffused light.

How did it get scale and how do I get rid of the scale? It's on several fronds including new ones, so I don't want to cut them. Someone told me to spray it with Neem Oil which I have in "Garden Safe" fungicide. It says it's safe for house plants, but since I've nursed this huge palm for all these years, I'm afraid it will kill my palm. Do you know what to do? Thanks.

My uncle Is a horticulturist, and he said to use the oil that you have, saturate the plant. It will not kill the plant but if you can he recommends to leave it outside while you are saturating it. Make sure you just spray on the scale only. IT will eventually leave you may have to repeat until it is gone.
He also said that you can rub it off with your fingers but that would be a messy job! Maybe use some rubber gloves, I would just saturate an spray for a while let it do it naturally..

Scale can appear for many reasons. You need to get rid of it because the next thing is Sooty Mould will appear and feed on the Scale excretions. Here's an organic recipe for White Oil (It makes a lot!) which will almost immediately smother and kill the scale:
1 cup of vegetable cooking oil (any kind will do)
Quarter cup of washing up liquid. Mix together in a jar and shake well.

Use 2 tablespoons in 2 pints of water, mix well and spray on the scale. (I'm an Aussie and checked the measurements :)

Both the undiluted and diluted mixture will last about 3 months. Maybe share with some friends, as White Oil can be used for lots of things.

I have a very large cattail palm in my home. It has scale and I can't seem to get control of it. I have been using warm soapy water and rubbing the leaves and stems once a month to remove the scale but it keeps coming back.
