how to clean tube bird feeders

I like to clean my bird feeders on a regular basis to keep my birds healthy. It's very difficult to find a brush that will get into the tube feeders.

I've seen a special brush on Amazon, sold by several vendors, but it doesn't look very robust and by the time I finish paying for the brush and shipping, it will be a rather expensive brush. I've looked in Walmart, Home Depot, etc. and I can't find a brush for bird feeders.

So I'm curious how people clean their feeders.

Thanks,
Sue

I usually use the type of brush you would use for a baby bottle - take the whole thing apart and put the brush in from the top and then in from the bottom!!
