Or grease, whatever. Please teach me about greasing things. The check arm roller in my door is squeaky. Last time this happened, I sprayed it down with silicon lubricant, which worked, but that was only three months ago, and since getting to the roller involves taking apart my entire door, that’s really not something I’d want to repeat quarterly.
My knowledge of greases and lubricants basically consists of “WD40 sucks as a lubricant” and “don’t use silicone near flames unless you want to die.”
