rev up your engines, now I've been using wd-40 for all kinds of things but it's
come to my attention that there are some things you shouldn't use it for that
I've seen people use it and cause problems so first I'm going to show you
things you don't want to use wd-40 for now numero uno is don't spray it on
squeaking fan belts or to be politically correct these days
serpentine drive belts now if you got squeaky
fan belts don't spray wd-40 on it I've seen people do it and yeah it'll stop
the squeaking for a while but the belts are made to run dry this is a serpentine
belt with all these grooves you do not want any kind of lubrication on them
don't even spray any of that belt ease it says stop squeak and belt dressing
these are made to run naked you don't want anything on them so if they're
squeaking they're either worn out and they need replacing or if they're
adjustable ones like my old Celica they need to be tightened up or if you got a
modern car with an automatic tensioner you might need a new automatic tensioner
but do not spray wd-40 on them now the next thing not to do is don't spray it
on your tires to polish them if you want to make your tire shine use stuff like
this blue shine that's made for shining rubber tires
think about wd-40 a lot of it is a lubricant you don't want to lubricate
your tires they need friction to drive down the road if you get it on the tread
or it migrates till the tread you can lose grip if you're a hard driver
especially motorcycle targeted treads that go way down the side you don't want
to spray it on them years ago I had a friend do that on his motorcycle and he
had a rocket 750 Suzuki and he was corning and he lost it slid on smash
the whole side his bike scratched it all off custom of fortune and repairs and paint
don't put wd-40 on your tires now another thing I don't advise people do
with wd-40 is to spray it on your paint and then polish it off you can see it
really makes it shine one over here shined up but this is
something devious people do before they sell you were used-car it will make it
shine like mad but it quickly fades off and then of course you got a faded car
and if you do want to paint a car you have to have all that stuff stripped off
it's not made for polishing cars only devious people do that and over the
years I've had a few customers buy a car like that look real shiny and then a
month or two later they brought it in said Oh Scotty my used car look the
paint looks horrible and I look at himself she stick probably sprayed it
with wd-40 and polished it all off so it looks shiny and the worst thing is I
just shined this whole thing to show you it really shows up well in pictures so
pictures of used cars look really good that way but hey you don't want to buy a
car like that and you don't want to be sleazy and polished went up with it and
then sell them to some poor person that finds out months later that the paint's
all shot now there are some very good uses for wd-40 realize that it's got two
main properties one is it's a water dispersant so let's say you go through
flood water or you were dumb enough to hose off your engine bay with one of
those big water sprayers that one of those do-it-yourself car washes and you
got water and all the electronics you can spray this all over the electronics
to disperse the water and the other property is that can loosen up rust
particles so you got old rusty bolts nut you can't get off you can spray them all
over let them soak overnight or a couple of days if you're in no hurry and they
can do wonders on that and to prevent rust specially on bare metal or even
painted metal that's old kind of crack they have these giant big blast ones I
know guys up north they buy cases of this stuff and then they spray all
around the bar and the truck and the wheel wells and the suspension arms and
everything to keep all that salt water from corroding stuff in the winter and
here in Texas I know guys that use in Galveston near the beach they'll spray
their stuff to protect it to keep it from being corroded by the saltwater air
that blows in from the Gulf and of course if you got squeaky parts or rusty
parts under the car just jack it up here's why I like this cool wand this one
came with so you can bend it and spray it wherever you want maybe your struts
are getting a little squeaky the mounts may be ripped under there the rubber hey
it's gonna help and you can go way up in the top spray that to not say I got
squeaky bushings where rubber goes in you can lubricate them you can go up
here spray anything that's starting to have a little rough so if you gotta take
it apart later it'll be a lot easier and if you got an old-fashioned car like
mine that still has a key you can stick the key in lubricate it all inside and
quick wipe the excess off and of course you can do the same thing on your
ignition key just spray the switch then no no we're gonna whine about that too
sale style you shouldn't use it on locks well heck yeah there's a lot of other
sprays you can use but I've been using this stuff for 50 years unlocks I never
had a problem the wd-40 doesn't harm any electronics so you're doing on the
ignition switch it's not gonna hurt any electronic parts if you have a system
where the ignition switch is right on the bottom where the key is
it doesn't hurt anything and yeah there's other stuff out there that
people swear by but I've been using this stuff for 50 years I've never had to
replace a lock switch on any of my toyotas and they do wear out eventually on
Toyotas the reason I use it on locks is because decades ago a locksmith told me
that's all he used he said I've seen you guys use graphite stuff and a graphite
will build up and block the lock he said that's why he is wd-40 they don't block
up anything and there's something you can partially use wd-40 for let's say
your door hinges are getting rusty we're just opening it up and spray the rust hinges
then you can't let it soak for a few days but then you should wipe any
excess off and use this now this is wd-40 water resistant silicone spray
it's not the wd-40 normal it's just the company makes the silicone spray too you
can use any silicone lubricant you want but then you spray the hinges with the
silicone lubricant because that's a pure lubricant and that will lubricate it
over time the wd-40 isn't lubricant it can Lube a little bit but
you'd want to do hinges any kind of thing that moves with an actual
lubricant so it's lubricating while you use if you use a wd-40 you'd have to
keep spraying it on because it's not gonna lubricate it over time and the
noise had come back but with this the silicone stuff is pretty water
impermeable oh you can only have to spray it two or three times here and the
squeaks will probably go away, one thing I like about the regular wd-40 is they
got these cool little tiny cans I leave them in a trunk of my cars so if there's
ever any kind of an emergency I like so maybe you go through a big
puddle and the car stops running cuz everything got wet you can get this out
you can spray it all over the electronics so that it'll disperse the
water and you'll be able to drive out a cute little handy things and on you get
some crazy squeak that's driving your nuts while you're on vacation you can
just get the little can out and spray it away so now you know things you shouldn't
do with wd-40 and things that you should do with it,
