I have a new handbag with 4 zips. To make them glide a little more smoothly I got a cotton bud thinly covered it in Vaseline then wiped it over each zip.
I also used the same cotton bud to run along the base of the shower so that the sliding door moved less jerkily.
Do you have any useful tips to share with us ?
Aah! I could definitely stamp and shout at the moment!
