Black crust build up in sigma max handle . - Tile Advice

[Dumbo]

Sometimes when going to use my sigma cutters the handle doesn't run smoothly and on removing it is find there is a black scale build up on the inside of handle . Questions.
Is their something I should be doing to prevent this happening . ( I do spray the bar with silicone spray to clean it but then wipe clean before using it again )
Secondly if this is inevitable what is best way of removing it .
Pardon my ignorance only moved over from the darkside a year ago so am newish to sigma .
Thanks in advance for any help offered

I Only use wd40 on mine. If some muppet manages to get sawdust everywhere, it can clog up but a blast with a hose and then more wd40 sorts it out.

I Think it's just rubi you can't use solvent on.
Maybe they melt or something?!

I'm same, dub dee on the bar and wipe with a cloth. Remove the handle spray inside and shove some blue roll through it or a cloth to clean and dry it. Biggest issue I had was a burr of metal on the rail which I had to sand off which took some coating off.

I've been having the same problem with mine. Cleaned it out with wd40 and some wire wool

Black build up is typical of anything aluminium that moves

I take the handle off and use something similar to this below with wd40 dry ptfe lubricant and then dry off with blue roll etc.
