Cleaning A/C parts

What's the best way to clean minor dirt and other impurities from A/C parts?
I have a condenser and compressor that have been on a shelf for a few years and I'm assuming a bit of dust and stuff has gotten into them. Can I just use water to flush it out and then blow it out with air? I know the system will get evacuated before it gets charged, but it seems like it should at least be clean before I put it together.
I want to get my A/C working so that if it ever stops raining and gets warm I can still be cool.

I would use air but definitely not water.

Re: Cleaning A/C parts

Use an aerosol A/C flush solvent to clean the inside of the condensor, then use compressed air to dry. Do Not flush a compressor!

Re: Cleaning A/C parts

definitely apply an a/c solvent via compressed air to flush the hard lines. The muffler (low side pressure hose --> evaporator to compressor) cannot be flushed. And certain consdensors cannot be flushed, not sure if ours is one of those...so be careful. At the very least you'll have to remove the trinary switch.

Re: Cleaning A/C parts

Not sure if you've already cleaned them or not, but I would suggest Non-Chlorinated brake clean.

Re: Cleaning A/C parts

they make ac flush solvent. it's cheap and easy to get. might as well just use the correct tool for the job. brake cleaner leaves a thin film when it evaporates, spray it on some clear glass and when it dries you will see the remains. carb cleaner is better but still not as good as the ac solvent.
