The only issue I’ve ever heard was the gas leaked out between the sliding door glass & the glass turned so Snow White you couldn’t see out. (Thermal Pane)

All good it rollers and not locked up.

Use LC Wax especially made for aluminum. Get it at Ace. It is the best.

The gas probably leaks out before the rollers lock up? :ho:

There should be an adjustment for the rollers on the bottom side of each door/panel. The adjustment raises the door/panel so the door/panel slides on the bottom rollers.

You may need to replace the rollers. I had that done on my former home and the doors worked like new afterwards. I would strongly recommend using a pro or a couple of guys with lots of muscle.

You should check if you have single or tantdem rollers on the sliding doors. Most sliding doors are installed with single rollers, which tend to ware quickly because of the construction debris that is left on the track. If the doors have only one roller at each side, have the rollers replaced with two, tandem rollers. Tandem rollers are built like the wheels on a trolley car or train. They distribute the weight better and the doors will slide with much less effort.

He is using it to clean not lubricate. He says he wipes it clean with a cotton cloth.

LC wax aluminum lubricant @ lowes, take hold in screw out not the adjustment screw this will allow lube to get on the rollers spray generously roll door back and forth this will make them roll better or make them worse if worse have rollers replaced.

There's a silicone spray called CRC in a red and white can sold at Ace that is wet when sprayed then dries and lubricates on the surface, not sticky.

After 20 or so years the adjustment are usually rusted so bad you can’t turn screw with out stripping slots out.

You can spray it all you want, but if rollers are not turning and sliding it won’t do no good. Now it the rollers are rolling then yes.

Do NOT Use any lubricating on the Tracks of The Doors
 

We had a similar issue and called a company called “Bay Area Sliding Door Repair”. Home page Tampa Sliding Door Repairs | Bay Area Sliding Door Repairs | Free Quote and their phone # is 813.712.0211. They have a flat fee for each door based on the number of doors you have to repair. They came out, removed the doors, replaced the rollers on the bottom with stainless steel rollers, cleaned the tracks, installed the doors and aligned them for proper operation.
They told us to NOT EVER pressure wash the tracks or place any lubricant on them. This will only attract dirt and sand from blowing/raining storms. Since we have had them out we’ve been very satisfied with their work. Straight up front with the prices no matter how much time they need to spend. One of the technicians were the owner’s son. They were very polite and up front about what people experience with sliding doors. This is about all they do and travel from Lutz, Florida to all the beach communities. We live in Inverness, Florida and they traveled from Lutz to service our doors which is about 50 miles. Did a great job and told us if we have any other problems they’ll come out and make it good. This was done in 2020. Would recommend them to anyone.
