Spilled soup on my KUL ES-87 keyboard

post #1 of 8
Thread Starter 
I've had a KUL ES-87 keyboard for several months now and I had my first accident ever on a keyboard: I spilled some soup on it. Normally, I move my keyboard well out of the way when i am eating at my desk but as I was setting the bowl down, I bumped it and some sloshed onto the keyboard (not much, maybe a tablespoon/15ml or less). I have since unplugged it, removed the keycaps in the affected area, and attempted to soak up everything I can. But I know that the liquid has seeped under the switches and onto the board below. I tried using some canned air to dry it out. Now after plugging it back in, some of the key presses are registering multiple keys at the same time, even keys that are not adjacent, Like pressing T sometimes registers one or more M presses. With my limited knowledge of circuit boards, I am thinking that there is still liquid under there that is completing a circuit between multiple keys at the same time, or i fried whatever brain the keyboard has and am SOL.

That being said, the keyboard has since been unplugged again and is sitting next to me as I type on this awful OEM Acer keyboard. I think my next step is to take the thing apart and give it a through examination and cleaning. Here are some questions i have though:


1. Does anyone know if the switches on this keyboard are soldered directly to the pcb or if they are removable? According to THIS review, they are plate mounted frown.gif

2. What is the best substance to clean the pcb? (Isopropyl alcohol?)

3. Will the answer to #2 dissolve the ABS keycaps?

4. Any other tips/advice for cleaning/repairing this board?

Yes, I am not going to be much more careful around my keyboards.

EDIT: came across this post which has been helpful, but unfortunately, the images are all dead links frown.gif

remove all the keycaps, and you can use either denture cleaning tablets or just dish soap and clean them off, if you can remove the pcb from the case, then do so and wash the case, and then for the switches, the easy method is iso alcohol and q-tips. The more you break down the keyboard the easier it will be to clean.

Some people wash their keyboards pcb in water, but I wouldn't do that unless it was a last case thing.

alcohol won't desolve the keycaps, but an easy way to wash them is if you have a small bag with holes in it ( jersey like material ) you can put them in the dishwasher. But a soak in soapy water and then dry them off with a towel while rubbing them clean usually does the trick.

Yea, you can disassemble this keyboard quite a bit so that is what I am going to do. The only thing I have read that clashes with your advice is that alcohol can dissolve the grease that is in the switches so is is best to avoid that or be prepared to re-lube them. I'll take it apart tonight and report back tomorrow or the day after once it all dries.

You know, it's kind of funny...

Threads like this-- "help, I spilled something in my mechanical keyboard, and now it doesn't work properly"-- are hardly rare. Yet, when manufacturers introduce features intended to increase the resistance of their mechanical keyboards to spills, dust, debris, etc., nobody seems to care.

Personally, if I were going to abandon my usual bargain-hunting habits and invest $100+ in a brand new and not ridiculously discounted mechanical keyboard, I would want to receive a keyboard experience that involves being able to drink a cup of coffee or eat a bowl of ramen at my computer without fear. The sad thing is that improving the survival rate against minor spills like the OP describes isn't that hard to do...but unless manufacturers see some interest from consumers for the attribute, it's unlikely that they'll be motivated to pursue it more often.

Well, all is well again. took apart the keyboard and cleaned the affrected areas of the pcb with isopropyl alcohol and after putting everything back together, it is working fine. Thanks all for the help.
