Scratchy volume controls

What can I do about volume knobs and sliders that become "scratchy"?

ie. On some of my house radios when I adjust the volume level I get loud
scratchy sounds coming through speakers as you turn the knob. Sometimes the
sound drops to zero until the tap the knob a few times and it comes good.


Any advice much appreciated!

** A few drops of WD40 will fix the noise.

With sliders this is easy - with rotary controls you will need to
open up the items to gain access.


BTW Anyone who thinks this is bad advice is an imbecile.

You can often shoot the WD-40 into a rotary pot where the end tabs are on
the control, without having to open it up.

Not sure why they would (although it isn't a permanent solution, it's easy
and quick), but nice pre-emptive strike Phil. A job awaits at the Pentagon!

** A few drops of WD40 will fix the noise. Hi,

In my experience, it works great over the short term, but attracts
dirt/dust on the pot over the long term.

Believe it or not, but this topic has been beaten to death.

** What ?? So WD is a dust magnet ?

BTW House dust is NOT the main cause of pots crackling - 95% I
treat have no signs of house dust.

Believe it or not, but this topic has been beaten to death.


** I know - and by masses of fucking imbeciles - mostly stupid Yanks.

That is WHY I posted my comment.

Nope but I'm sure there are plenty of other volunteers here willing to
hold you down whilst I administer the nasal personality modifier to
you.



** So Martin thought you were too crazy for him ?

Too violent and demented for the countries worst mass murderer ??

He preferred to act alone - no gang or lynch mob needed like you want
to justify your crimes.

Lets put back the bit you snipped :

** He preferred to act alone - no gang or lynch mob needed like

You seen to know him quite well.
One of your relatives perhaps? Or just your hero?



** You avoided the issue.

I was using it almost anytime for 30y /except for PC fans & high
voltage stuff/ w/o any consequeces ...



** Same here. With common sense you will have none.

Do not use large amounts and keep it off RF circuitry and moving
rubber parts.

Remember Servisol and Super Servisol ?

I don't know about WD40 (is it flammable - or is it non flammable ? )


** The propellant gas is CO2 nowadays - but fine particles of oil and
solvent will flame in air.

Best not to spray it on anything red hot.


as I haven't used it, However the electrical spray CRC 2-26 I find it
works well on the high voltage (EHT) section in TVs.


** WD 40 is very similar to 2-26 ( which used for many years) - what
one does the other will do.

2-26 works well on pots, connectors of many kinds too. I even spray
pots etc from new to help protect, lubricate and extend life.


** So do I sometimes - but don't brag about it - the anti WD forces
will have you on toast.

** Ross - the word "seems" does not have the same meaning as the word
"does".

Only a ratbag would not realise the obvious difference.

You have raised ratbaggery to an artform.


** You are inventing hypothetical problems that do not exist - same as
all anti WD loonies.

** You are an utter fuckwit Ross.


** You posts here show that fact. You have not presented one example
of damage or a reason to not use WD on pots and switches. Thousands of
techs world wide use it every day - since you worked for an organisation
that banned it YOU are probably unaware of that.


** That is again drawing a false conclusion from no evidence.

You have cast unjustified doubt on my good advice - since you have
not got a clue. That makes you just another anti WD paranoiac.

Can you account for my and others 30 years of good results and no
damage with WD ?

Alternatives like CRC 2-26 are so similar as makes no difference -
and it is recommended for electronics.



** Want to try again Ross - that last effort was pathetic.
