In my vaccum cleaner, plastic hose and steel extension tube are stuck.How can i unlock them?will any product like PB blaster or any penetrating oil help.Can someone please advise..
the cooking oil is a great idea. also sometimes some of them need twisting
On the steel extension tubes you could use a touch of wd40. This may work where the tube connects to the plastic hose as well, but wd40 can have an effect on some plastics, so take care. It maybe better to use a drop of cooking oil.
