Coconut oil works very well to make heavy glass siding doors to move easier. We just had our windows/glass doors professionally cleaned.
We have 3 large/heavy triple glass sliding doors which got harder to close or open, so I asked the cleaner what he recommended for the sticking sliding doors.
He recommended coconut oil.
Step 1. Vacuum the dirt/crud from the slider rails.
Step 2. Clean the rails with some of the new wipes.
Step 3. Let the slider rails dry and then add the coconut
with a rag. Slide the doors and add more oil where
the door sticks.
Step 4. The next day and clean the rail with the wipes and
add more coconut oil. Works better if it is warm
outside.
Every 2-3 weeks or when needed repeat #1-#4.
We have found a healthy use of our coconut oil.
Does the coconut oil in the sliders attract ants? That would be a concern where I live. Have to spray all the front walks, stoops, porches and doorsills with Raid every spring.
