Lubricate Reusable Caulk Gun Plunger

first tip i'm going to talk about is lubricating the tube about every 10 to 20 sausage packs that you put in here and use you're going to want to lubricate this plunger because it could get gunked up it could start running a little bit stiff so you want to lubricate it one of the ways i lubricate it is just with mineral oil i get these little small bottles of mineral oil with the um the reels that i buy for fishing and it's a very handy little thing to do another thing you can use is like cooking spray like pam cooking spray you can spray that down inside there that's a good lubricant itself but i just take my little bottle of lubricant which i just keep in my painting vehicle i just put a little dab of the lubricant down in there and then i just rub it around with my finger and rub it on the other side the plunger is up in the air at all and i'll just rub it inside that caulking tube there and i'm going to just take install my tube just going to run the plunger down until it hits that lubricant and then i'm going to flip it over push it down the opposite side
