Ageing mother is having trouble with the bi-fold door on her square shower cubicle. I seem to recall it runs on nylon slides or similar rather than wheels or rollers.
I am going over on Sunday. Any advice on lubricant or other ways to make it run a little more easily. Mother has no great strength in her arms and just a little less friction would help.
No idea of make or model. It is fairly new but mother would have gone for cheapness rather than quality.
TIA for any ideas. (No she won't pay for a nice offset quadrant with easy gliding doors like I fitted here earlier in the year!)
