Reddit reviews Herco® HE76 Nylon Trombone Flex Brush

That's hilarious, I've never actually noticed anything unusual before in stuff like that. But now that you mention it...

Turns out car\Miata stuff pops up on this trombone cleaner.

I don't have a garage, so unfortunately mine stays out in the elements year round. It had a small leak at the window seal when I got it, but I adjusted the windows and now it seals and I have had no problems since. It was a little blacker in color when I got it but the dealership probably used some restore stuff to shiny it up and I could do the same and it would be fine. It gets dumped on with pine needles and pollen and rain all the time but I wash it a lot to help. When it's summer and dry and pollen gets on it sometimes I have to use a soft brush when I wash it to get the pollen out of the textured surface. I think that's about it. Mine has held up fine. But I'd be a million times happier if I had a garage.


Edit: get a trombone cleaner to clean the drain holes, mine get plugged with pine needles so it's regular maintenance.

Edit: here's the trombone cleaner I use:

/u/Champagneshallow is correct. Drain holes for rain. You should have another on the passenger side.

Buy a trombone brush and give them a clean once in a while. https://www.amazon.com/gp/product/B000K3E9KO
