Thanks for posting this. Unfortunately I only read it today after I had the bottom off of the KLH 20 to clean the potentiometers and switches. I used Nu-trol 401B which worked great for everything except those slider switches. I guess I'll pick up Faderlube unless you or someone else has a better suggestion. I realize this post is ancient, but maybe you'll see it!As the owner of a TWENTY having torn it down and rebuilt it.
The 20's switches are buried under the chassis and have a longer than normal switch "arm", causing the slider to cant over and bind. It's inherent in the design of the ones with the slider. Later models had "rocker" switches.
You'll have to open it up from the bottom, and spray them with De-Oxit D-5, cycle them 30-40 times, then Faderlube or Progold. The only thing electrical I use WD-40 on is to De-Water Distributor caps during rainy weather.
If you are competent with metal working, you could open the mounting holes, and install rocker switches, and open the top plate to fit the rockers. The top plate is plastic with a light metal cover. The plastic is brittle and you'll more than likely end up having to epoxy the standoff's.

If you add an @ to his name Iike this, @larryderouin. He will get a notification. That tends to make it much more likely he’ll see it.Thanks for posting this.
