GUYS!!! BEFORE YOU DO THIS - try my easier method! Press the master volume knob into to the interface and start to move it from MIN to MAX. Do this 5 to 10 times. THE MAGIC happens. Keep on mind that you have to pressing the knob while moveing it. This will clean the contacts. If you want the spray method, you are still ok to go. It's a better to clean it, but it's time waste for all assembling. Please comment if that works for you, It worked for me on the master volume knob as in the video.

For non engineers here, I just opened the volume cap, sprayed some isopropyl alcohol, turned fastly the knob (do 3 times the proccess), and it fixed immediatly. It took 5 minutes.

I just applied this method to my Focusrite Scarlett 2i2 3rd Gen, simply unscrew 2 screws on my model, remove the case and apply the product on the input area of my left monitor (this was the one that squeaked when I turned the volume up/down from the sound card) and on the volume knob. After waiting 2 minutes for the product to dry I proceeded to check if it was fixed and indeed, I can raise / lower the volume of the card without having to hear the annoying noise. I hope my review will help you, any doubt you can reply it and thank you @Little One for sharing this method to solve this problem.

I have this issue for years. Now I cleaned the potenciometer and it really helped, even if the pot is sealed. That is awesome! Thanks for the video!

thank you for this video - it helped me. I used wd-40, sprayed it inside the volume knob, turned it few times and it helped me to turn it without any noise. Actually, I had not only a noise, but sometimes my right channel was off while I turn volume knob. So now it works without noise and without sound dissappearing. Thank you a lot

Thank you very much. I've had the issue for years now. I had even started to worry that it would affect my new pair of monitors and headphones.I used Isopropyl alcohol since I wasn't able to get the contact cleaner and it worked perfectly. I'm now very happy...🥰Saved me a-lot since a technician i had asked was charging around 20 dollars for that. It didn't even take 20 minutes

they sell electronic contact cleaner everywhere but i think starting fluid is similar or if you have like O2 (oxygen sensor) cleaner spray in a can that will work too or maybe rubbing alcohol? also known as isopropyl alcohol? if you go this route make sure to get the highest ratio of alcohol and least amount of water. because at the dollar store for instance they sell like 80% alcohol with 20% water so its super diluted and of course water is something you dont want on or in your electronics and hardware. also there's a cleaner spray in a can called Deoxit i believe thats pretty expensive BUT is made JUST for pitch pots! and i believe deoxite brand also make and sell a lubricant spray that you should use to lube the moving parts after cleaning them because the spray cleaner will remove a lot if not all of the lube thats inside the pots. anyways hope this helps! also WD40 isnt always the best option either because im pretty sure its a well known fact that in long run it can actually attract dirt and other debris and make that crap stick to your equipment. I've also been told to NEVER use WD40 in car door tumblers (where you put the key in to unlock car doors) to clean or free up sticky tumblers because again it will attract more unwanted contaminants in the LONG run !!! ok that is all

Not sure if it's recommended, but Turning the knobs back and fort will eventually fix it entirely for me, until it comes back after a short while. As this is probably accumulated dirt, one could try to cover up the interface when not in use, to prevent it for longer. My interface is always in use, so I haven't been able to try it myself though.

Thank you for making this video. As a last resort before buying gen 3 or gen 4, I found your video and this information fixed the problem. Thank you again sir! All the best for you.

Tu es le boss, ça fait 3 ans que ça grésiller maintenant plus rien :)

Sometimes you just have to twist the knob for a minute or so and it dislodges the bit of dust that causes the problem.

thank you , I fixed mine with this method , thank you for sharing this

Why does the inside pot even get dirty in the first place? It could be a design flaw I guess. This issue is really annoying.

so it wasnt just me.... this has been driving me insane for years on my 2nd gen 2i2

I don't get why you removed the circuit board when the contact you sprayed is accessible through the cut-out in the circuit board. Surely the thing that needed removing was the outer casing🤔 I will come back and update when I've done mine which needs attention. Hence why I'm here. Thanks anyway

that i had been looking for

Actually front panel is removable and it's much easier to remove it than circuit board 😂 Mine 2i2 was not only noisy but also left channel on the headphones output was more quiet than right one so I begin to thought that my right ear is begin to become deaf. Will never buy focusrite product again

Mine is super noisy, and if I just remove the knob and spray in the front through the spot haft gap? did you find an opening in the pot from behind? Thanks

Not sure why you're opening the whole thing, just remove the knob and the nut and spray the area. That solved my issues with 1 minute of work at most.

thanks but how is that posible i have it 3 months and it does that now? it's wierd

mine is scratchy and in some spots my right side channel goes out and I only hear audio from left channel :/ hopefully this fixes that as well

K time to buy a new interface 😅

It’s it possible to just spray it on the knob it self without taking it apart? I have heard people say that that is a solution as well.

i think its time for me to just replace the filters completely after many years on the road

used this same method to fix mine a couple months ago but now I'm missing the smoothness of the knob... anyway to get that back?

I can't find contact cleaner in my area, pls what can I use as a substitute?

Thanks man Is that a harmful noise?? cause I can't open the sound card

Opened my 3rd Gen Scrlette and it's made cheaper than the 2nd Gen. Go figure.

How long does it hold on? Thanks, dzy

Guys, stupid question coming from an non engineer, why does this happen???

Can the crackle sounds damage your studio monitors?

If you people take apart your soundcard like this guy did, I won't be surprised if you break it. Amateurs should not be doing this kind of work. Leave it to a professional.
