Spilled grease in my phone. it still works but has grease in screen. I want to open up the casing and clean it out. How can I?

Like all water damage on electronics, it is critical to do the following right away: (1).Remove the battery to slow down the corrosion process. (2). Have someone remove the case to expose the circuit board. (3). Assess the damage. It's easy to see where the water/moisture is as you should notice a whitish/greenish deposit at the spill site.
If it's minor, you might be able to clean the damage and resume operation. Good luck, hope this helps.

A very small amount of degreaser spilled in a large commercial fryer is harmless, but if in doubt, discard the grease, thoroughly rinse the vat with clean water, and allow to drain completely before refilling with grease. Recycle used grease. do not pour down a drain or storm sewer.

This moisture can accumulate from certain types of cooking (lots of boiling) in the microwave or in extreme cases, from a blocked grease filter or exhaust vent duct.

Spills or large amounts of accumulated moisture should be wiped off. Minor amounts can dry out by themselves easier if you leave the door open after cooking.

Also, when boiling on the stovetop, you should always use the hood vent exhuast fan to keep steam and grease out of the controls and the door area of the microwave. I always recommend using the vent fan with any cooking on the stovetop.

As long as it is not rusting the metal mesh screen or other parts of the door, it can be allowed to dry out over a period of days with the door open.

If it is a convection microwave, using the convection heat will help it dry.

Dear Sir,
Normally when one closes the gun the machine stops. So you may have a blockage problem that is shutting the machine off. You may try to diusconnect the gun so that you run the machine without load. But..ALWAYS...with water being fed. Never run a power washer without water being fed. Without gun and water fed normally....your machine should continue working. If so you can attach the gun without the lance. If it works, you have a blocked nozzle in the lance. If so try with a very thin needle to clear the nozzel. Do not make the nozzel's hole bigger with cleaning, because then you lose power. Now these machines stop automatically by means of a control valve (Spill Valve). The spill valve when the gun is closed, pressure is created and the spill valve in turn will move to close the electricity by means of a micro switch. Spill valves give a lot of trouble if machine is left with soap in it, or if the machine is stored with pressure in it. NEVER STORE A POWER WASHER WITH PRESSURE IN IT.....always when finished working disconnect electricity, disconnect water and finally press the gun to release pressure. Well as I already said start by putting on machine without load. Then add the gun without lance so that you see that when you close the gun the machine stops....and when you open the gun machine starts again. All this without lance attached. Also in cases like these the Spill Valve sometimes gets jammed in the cutting off electricity position. Spill valves only need to be serviced with good silicon grease....but in doubt change the spill valve. If you open the machine the spill valve is located where you see 2 wires coming out. You should have special tools to remove and service/change the spill valve. Well hope you have a small idea from where to start.

Dear davedulmage,
To see if the unit is OK....first you must switch it on without water and without high pressure hose and gun. If machinr works smoothly, try by attaching a water supply. Now run the pump with water coming out of the outlet. If also in this case all runs smooth, then attach high pressre hose with gun but without lance. Put on the machine with gun open(to reduce initial resistance) and when you see a clear flow of water coming out...close the gun. The machine should stop. In this case I am suspecting that when you open again the gun the machine will not work. So it seems that when pressure is built in the pump a fault is occuring in the Spill Valve or also called Control Valve. When the gun is closed and pressure built up, this spill valve contracts and switches the pump off. When the gun is opened, the spill valve extends, putting the machine on and closing a valve at the base of the spill valve. So in your case it seems that the spill valve needs to be renewed. A spill valve gets stuck by incorrect using of the pump. For example leaving the pump with pressure in it for a long time. Also it gets stuck by detergents and chemicals. Sometimes I lubricate Spill Valves with high quality silicon grease....but it is much more practical to change it. When a new spill valve is put in....always run the pump with no load. This by usiing the gun without lance or wands, resulting in low pressure. If all OK...add a lance or wand that you are sure it is good. One final thing....to get to this spill valve you must put apart the body and expose the pump. If you are not that good at doing this job...it is better done by a more knowledgeable person. But changing the spill valve is worth it....because it is cheaper than a new machine.

Dear Tigger82 (also montaver2000),
This explaination is relavent to various Karcher models, especialy your model. When you are using the machine with the gun open....presurised water comes out of the lance. When you close the gun, the machine stops. This happens by means of a Spill Valve or often called the Control Valve. When the gun is closed, this spill valve cotracts with built up pressure and at the same time works on a miro switch which cuts the electricity....and thus stops the electric motor. Now in many cases when the gun is again opened, this spill valve sticks and keeps the electric circuit closed.
In all cases you must open the cover, and locate this spill valve. Sometimes it is easy to see a micro switch on it. If you remove the miro switch from the spill valve the motor will for sure turn.
Now the spill valve gets stuck for many reasons. One of the reasons is that you leave the machine under pressure for a long time and even store away the machine with pressure still in the system. A spill valve also gets stuck due to detergent. I sometimes service the spill valve and lubricate with special solicon grease. But the best way is to change the spill valve with a new one. So in a few words, the spill valve is stuck and leaving the microswitch off. So the electric motor cannot turn. One final hint is that sometimes the spill valve is difficult to remove. So all one has to do is attach water supply and switch on the pump. With the pressure produced the spill valve will be pushed out. In my oponion this job must be done by a person who knows what he is doing. Carefull that you have safety electrical breakers. See that you have safety shoes, safety gloves and eye protection.
Regards,
Fulltech.

regular oven cleaner such as Easy Off

Chances are spills or steam is accumulating during cooking.

After steam or spills, it's best to wipe the moisture away and even leave the door open a while to let it air out.

The "turning slowly when you open the door" you mentioned is probably normal due to door switch timing, unless you feel the door latches or door latch holes may have some grease buildup, in which case they should be cleaned.

Always be sure to hit Stop to halt cooking, and never open the door while it's cooking. That shortens the life of the door switches and can lead to erratic behavior.

If the cavity metal of the oven is chipped or charred, it will have to be sanded smooth and clean and dried thoroughly.

Then you can apply some high-temperature appliance paint, available from places like Wal-Mart, Lowe's or Builder's Square.

Dirt. Spilled oil, grease, milk etc. act as isolator and prevent contact between burner and casing (mass). You need to clean up burners, scrub all the dirt and make sure their seats are cleaned too (brass elements below burners).
