I just installed the first couple of switches on my layout and I’m still trying to get the points to move freely. Seems that even the finest bits of dirt and grit under or around the moving parts can cause binding. Any tips on how to prevent this problem? I think even if I didn’t ballast the switch at all, the surrounding soil would eventually work its way in, especially when it rains.
I ballast mine with horticultural grit on a rather minimal basis . I have seen suggestions that if you use the old indoor trick of dilute waterproof pva dribbled on it will hold it in place but i have never tried it.Some say use a tar coating under the track - heated then press the grit in - susequently vaccum any rubbish up. No real 100% certain method that I know of but pleased to know of one if there is.
I use a MINIMUM amount of ballast in my switches. Hardly any really. Sweep it clear with a paint brush ensuring that none is in contact with moving parts. My real problem is when the dogs decide to make a “deposit” on or near the switches, and then they kick some dirt into the switch.
I go out with a stiff brush and clear the points prior to running, and carry it with me when I am running for the odd piece that gets kicked into the points. It doesn’t really matter what extremes one goes through, crap will make its way into the points and need to be brushed clear. Just the act of running trains over them is often enough. But hey–the prototypes carried brooms on board for a reason, too.

I use an old stiff paintbrush. When something really gets stuck, I resort to dental picks and other medieval dental torture tools. They serve double duty and plauQE removers
