After I finish use of hair dryer, I find it very difficult to pull the plug out from wall outlet. Can I use WD-40 to lubricate the plug? Any danger of short circuit or electric shock?
Don't use WD-40, it can become non-conductive over time. Use electrical contact grease (also known as dielectric grease). First, though, make sure the plug is not damaged or bent.
Holy **** no don't lube it. you will just have to deal with it. or replace it or pay someone to replace the outlet. you will get your self hurt. trust me i got the s**t shocked out of me it dose not feel good at all. if you want i can tell you how to replace http://www.youtube.com/watch?v=vfZAE1VQPEY this tells you how. good luck
Go to the hardware store(Home Depot) and buy a converter plug that you plug your hair dryer plug into.Sometimes the plug is just a little too large(your hair dryer plug) for the holes in the wall outlet. So if you get another plug that fits better you won't have any more trouble with it.Tell the staff at Home Depot what you need and they will show you the right plug to use.Shouldn't cost more then 3-4 dollars and it will save you from fighting with your hair dryer.btw=Never put anything into an outlet but a plug or your wires and maybe more will be fried ;)
I put a drop of oil (like 3 in1) on my finger, rub that finger with my thumb to coat them both, then pinch each tine of the plug with them to give the tines a thin coating of oil. Wipe away any excess then plug it in to transfer a tiny sheen of oil to the contacts on the receptacle. It only takes a tiny bit of lube to make the receptacle work like new. It will not cause a spark or shock.
