dtr20 Posted November 8, 2017 Share Posted November 8, 2017 I'm working on a pair of cornwall verticals. I was curious on how to clean the inside of the metal mid-range horns. Since the horn has been vertical since 1973, half of the horn looks really dusty/dirty. Thanks Quote Link to comment Share on other sites More sharing options...
Marvel Posted November 8, 2017 Share Posted November 8, 2017 Are you going to remove them from the cabinets? If so, with the drivers removed you can scrub them with detergent and an old toothbrush. They are aluminum and it won't hurt them. You can spray paint, too . Bruce Quote Link to comment Share on other sites More sharing options...
dtr20 Posted November 8, 2017 Author Share Posted November 8, 2017 Yea, the horns are removed. I am asking because I am being cautious with chemicals because I don't want to cause discoloration of the black.

ricktate Posted November 8, 2017 Share Posted November 8, 2017 I cleaned my Scala horns and used emery cloth to smooth the seams. The used rustoleum black enamel to paint them and they look awesome. For the throat I used a dowel rod to sand it. 1 Quote Link to comment Share on other sites More sharing options...

I have a large bastard file and had spent over an hour on the one horn. It's way better but not done yet. I'. then using a high fill auto primer in a rattle can. I won't be painting mine black when I am done but looking at some other colors. Bruce 1 Quote Link to comment Share on other sites More sharing options...

MookieStl Posted November 9, 2017 Share Posted November 9, 2017 I power washed a beat up pair of K400s. These had been abused and the paint was flaking off. Spray painted them afterwards and they looked great. Quote Link to comment Share on other sites More sharing options...
oohms Posted November 10, 2017 Share Posted November 10, 2017 For old dusty gear, a damp (not dripping wet) microfiber cloth works wonders. It takes off a lot more than you expect and is very gentle Quote Link to comment Share on other sites More sharing options...
Marvel Posted November 10, 2017 Share Posted November 10, 2017 Those k-400 horns are heavy cast aluminum. You aren't going to hurt them much by scrubbing away at them. Those look great, Mookie! Not sure on the color for mine yet. Quote Link to comment Share on other sites More sharing options...

I am asking because I am being cautious with chemicals because I don't want to cause discoloration of the black. Sent from my SM-G930V using Tapatalk I use Simple Green on all my horns. Scrub them with a soft brush and rinse them with a garden hose. Towel dry them or let them air dry. Depends on the time of year. Does not harm the finish and makes the job very easy. I only repaint if I think it will make a huge difference. You can use this method on certain grilles also. Material dependent. It can make some of the older grilles look brand new. If I use this method on a set of Khorns I am restoring/rebuilding for example, I just spray on the Simple Green, let it sit for a couple minutes, lightly scrub them and rinse them off. The frames are painted so they are somewhat protected but I blow off the excess water right after cleaning with a compressor so it does not just sit on the wood. Helps the fabric dry faster too. If I do not think they will come back to "as new" with a cleaning I of course replace the fabric. I have plenty of factory black and brown cloth that I bought from Ralph at DuraCrest many moons ago.
