D5S-6 CAIG DeoxIT 5% Spray Contact Cleaner, 5 oz.

perfect to get rid of scratchy noise from your pots

I first encountered Deoxit when editing a music magazine. The distributing company sent out a sample kit. I promptly took it home and attacked my old NAD 2020, a Norwegian designed and Chinese built integrated amp for our stereo system, vintage....1976 no less. I'd pushed the NAD aside for a couple of years because every single pot, knob, any moving object that adjusted the sound had gone terribly bad. The loud rude noises and fire cracker crackles sometimes got the dog jumping from his repose on the couch. With one treatment with spray and some wipes, and not having to go inside the unit....did it all from the outside....it totally cleared up all the problems: made pots, knobs, sliders, etc, easy to set in motion. Eliminated completely any noise: snap, crackles, pops. Completely. Only recently, ten years later, has one of the knobs exhibited any noise. You spend a little more on Deoxit but it saves you big time.The next occasion was a few weeks ago and purchasing the Hosa Deoxit spray from Amazon.ca for a problem in my home studio. Similar results, perhaps not as dramatic, but the deal is this: it cleans and clears anything out of the way of the audio signal path. With no impediments, no sludge or oxidized soldering jobs, connections, etc the result is better, fuller, clearer sound devoid of those snaps, crackles, etc. Follow directions. Do not use and operate a motor vehicle. Seeing if you're alert. Tbw

強力な洗浄作用接続端子とか、分解したスイッチの接触面の洗浄に使用用途によりGシリーズやFシリーズとの使い分けD5は洗浄が得意で強力に異物や酸化膜を洗浄した後必要に応じてＩＰＡまたはエタノールで洗浄します（D5そのもので流してしまうこともあり、ケースバイケース）仕上げにＤシリーズ（金メッキ端子、接点）とＦシリーズ（炭素系ボリューム摺動面）を使い分けていますあとは、おおざっぱなアメリカ製らしく噴射量の調整が不可能（3段階の意味なし）なので、いったん小瓶内に噴射し、綿棒やピンセットで少量塗布というやり方をしています。このスプレーで直接噴くと基盤や手がギトギトになりますただ、昔のサンハヤトの接点復活材みたいにキトギトべたべたで埃付着と言うことは無く、比較的良く乾燥した感じになるので自家使用で、鳴れば良い・面倒くさい・速攻でなんとかしたい場合はノズルで吹き込みます（周囲に垂れた液を綿棒で吸い取っておけば拭き残しが有っても、後々べたべたに埃が積もると言うことは無いです）

Ecxelente producto, un poco caro, pero bien vale cada gota

Rated by the industry for reviving and cleaning dirty potentiometers or scratchy faders, and any other bad-contacts/switches. This has been the cheapest price i've found online but it is still quite expensive for what it is. Not sure if we are paying for a magic formula or the name. Perhaps there are cheaper alternatives out there but trial and error testing the competition may not be a cost effective experiment.

The Deoxit D5 arrived within 4 business days of my placing the order. I bought this stuff to service wafer switches and tuning capacitors in my vintage SW radio gear. The other versions of DeOxit do work on other electronic surfaces (potentiometers or gold-plated fingers for example), but this seems to be the best stuff for corroded switch, relay, and variable capacitor bronze fingers. As the wafer switches are difficult to impossible to repair or replace, you want to try to clean and refurbish them whenever possible rather than swap them out for problematic used units or hens-teeth NOS units. This does the trick on anything that is not physically damaged (I.E. bent or missing switch fingers). It is also not cheap. Fortunately, you need very little to have the desired effect (reliable connections between moving contacts) within the device being serviced. As a bonus, the can has an “L-M-H” setting on the spray button. I have found that the conservative “L” setting has always been fine for my intended purpose. This is my third purchase and I will buy more as required.
