How-to Clean and Lube Magnetic Faders

Rane’s patented non-contact faders, also known as magnetic faders, are designed with materials highly resistant to corrosion and most chemicals. While they will handle millions of operations (yes, we tested it), they may become dirty over time.

In order to maintain the feel of your faders, they may occasionally require cleaning and lubrication. The bearings in the fader work best with DuPont Teflon Multi-use Lubricant. This lubricate is commonly found at local hardware stores in two different form. A droplet type lube and spray type lube. Either will work fine, but the droplet type lube may be easier to control and less messy.

This lubricant is different than the fader lube previously recommended (Caig’s DeoxIT Fader Lube). This new stuff goes on wet to deeply penetrate moving parts, but sets up with a clean, dry, long-lasting film which will not attract and absorb dirt and grime (yay!). Wet or oily lubricants may feel good at first, but will attract dirt and evaporate or become dry over time.

Cleaning your faders is quick and easy, but you’ll need to first remove the fader from the mixer by removing the fader panel faceplate covering your dirty, little fader. Grab a Philips screw driver and follow the instructions below.


Fader Removal

1. Remove the fader knob(s) from your mixer. If using the MP25 or MP26, simply remove the crossfader knob.

2. Remove all screws holding the fader panel faceplate and put them somewhere safe.



3. Lift up the fader panel faceplate and set it aside where it won’t get damaged or scratched.

4. Remove the two screws at each end of a fader, holding the bottom of the fader in place with your other hand, so that the fader doesn’t fall into the mixer.  

5. Take the fader assembly completely out of your mixer (this makes cleaning much easier).

6. When you have the top panel off, we suggest removing one fader at a time. If you happen to take all three faders out of your mixer at the same time, please note that the left connector goes to the left fader, the center connector goes to the crossfader, and the right connector goes to the right fader. Crossing these cables up won’t hurt the mixer, but it will mess with your head a bit.

7. Unplug the connectors of the white wires at the fader assembly without pulling the wires. Yanking on the cable can damage the connector, so be gentle.  

8. When you're finished cleaning the fader, plug in the connector before re-installing the fader (yeah, you’d be surprised). If you’re using the Rane TTM 57SL, it is important to connect the cable so that the red line matches up with the #1 screen printed on the PCB board next to the plastic connector jack housing. If the cable is connected backwards, you will burn out the fader's hall sensors, making the fader inoperative. In addition, be sure to connect the cable to all 6 pins. Missing pins when connecting the cable will also fry the hall sensors.

9. Test all the faders before installing the fader panel face plate and fader knobs (don’t let Murphy’s Law get the best of you!).


Fader Cleaning

1. For a light cleaning, move the carrier to one side and wipe rails with a lint-free cloth. Move the carrier to the other side and repeat.



2. If heavier cleaning is required to remove oily lubricants, grease, club grim and etc., first take the carrier off of the rails by removing one of the endblocks. Clean the rails using a lint-free cloth and isopropyl alcohol (rubbing alcohol). Use a cotton swab and alcohol to clean the carrier bearings (i.e., the holes the rails glide through).

3. With the fader clean, dry and assembled, add a couple of drops of Teflon Multi-use Lubricant to each rail of the fader. Clean any excess lube that may have dropped onto the circuit board.



4. Move the carrier back and forth several times to distribute lubricant.

5. Do not disturb the position of the small sensors at each end of the fader. If you accidentally do, make sure the parts are standing straight before re-installing.



You’re done! Now go have fun with your slippery, smooth, like-new faders!
