John,

Assuming you're talking about cleaning up that TH6DXX that you have=
 instructions coming for....

Don't try to use chemicals to do cleaning on it. The only spots that need=
 cleaning are where one piece of tubing joins to another. The best thing=
 for those areas is a wire brush. I get a rotary wire brush that I can=
 chuck up in a rotary drill, and use it to thoroughly clean the outside of=
 the tubing. I then get a couple of wire brushes that plumbers use to clean=
 copper water pipe and use them to clean the inside of the tubing. Get at=
 least two sizes... here in the states the common sizes are 3/4 inch and=
 1/2 inch. Start with the larger size tubing in the antenna and work your=
 way down to the smaller sizes. The brushes will wear down, and allow you=
 to get the smaller sizes of tubing clean also.

Go to an electrical supply house and get a bottle of aluminum no-oxide=
 grease. It comes in a variety of trade names, but any good electrical=
 supply house should carry it. It's messy stuff, so have a good supply of=
 paper towels or rags on hand. Aluminum will oxide very quickly, and the=
 grease will stop the process and provide lubrication for the joints so=
 they do not freeze up or seeze (sp?). As soon as you have finished=
 cleaning up a piece of aluminum on the antenna, apply a coating of the=
 grease. Not five minutes later, but as soon as you have finished cleaning=
 it. There are lots of ways to apply the grease, but I have yet to find=
 anything better than a finger. Rub the grease onto and into the aluminum,=
 so it is covered with a light but solid coat. Be careful then where you=
 put the pieces down, as they will love to collect dirt if you let them.

Now, when you go to assemble the antenna, you will find that the joints=
 will slip together easily, and you will never have a problem with noisy=
 joints, intermittant connections, or being able to take it apart again ten=
 years down the road. It definitely is a bit of work, but worth every=
 minute of it for an antenna that will work perfectly for many years to=
 come.

Hope this helps.
