Adding crusher to build up the planum at Bergün results in some of it getting into the frog and throw bar area on turnouts. Someone somewhere mentioned using a stiff tooth brush, on which the handle has been sharpened to a point, for easy cleaning.

Works very well and is bent at the required angle.

I wonder if a battery operated electric one would work better? Probably harder to get the handle sharp and still hold the battery in, but it may be an option to try.

I took an old 4" paint brush and cut off about 1-1/2" from the bristles and tapered the back end of the handle to form a wedge shape to use when ballasting the track. Same principal. I like your idea of using a toothbrush for switch points.

If nothing else, you can use it as a shank in prison…

Have tried the cut off brushes, and other remedies… Use a regular screw driver as an uncoupling tool… It also works to get grit and stuff out of the way for swtiches… Saves having to carry too many tools…

I can’t use one , my toothbrush is electric (1/22.5 scale of course)

Actually , the toothbrush is a good idea , they have many useful applications .

Just a bit of lateral thinking is required .
