I wanted to know how to do the following:
1. Cleaning an Under Gravel Filter. I believe that a lot of debris and other dangerous stuff can go on accumulating under the plates of a UGF, which can later act like a time-bomb and cause a sudden spike in ammonia and nitrites.
How to clean under a UGF so this does not happen. Are there any other ways of preventing it?
Also how often should one clean under a UGF?
2. I have heard that a safer alternative to a UGF is a Reverse Under Gravel Filter. Can one convert a UGF into a RUGF, and if so how to do it?

1. Use a gravel cleaner that is readily available in any LFS. You can also use a pepsi bottle cut at the base & fitted with a hose pipe at the bottle opening. This sort of cleaning will effect your denitration in the tank but the removal of detritius will be very benificial too. once in 15 days is a good way to go if the tank is stocked & fed lightly.
2. A reverse RUGF will only work effectively if the powerhead pushing the water into the UGF is very powerfull, the gravel size is big, there is a very good prefilter to the pump at its water inlet & the prefilter is cleant frequently.
Dumping the UGF or the RUGF and getting a sponge filter would be the easiest option.
I second that....."DIT TO".... UGF require daily siphoning actually, but if you have Goldies, then forget it.. throw it immediately and get a better filer...
I had this lurking feeling that someone would advise me the above
And what more, I'm inclined to agree!
But seriously guys, if I did try to do the above, how am I supposed to go about it?
I have some nice fishy friends living in the tank. And I've heard that when dismantling a UGF, a lot of dangerous stuff (detritus, ammonia etc) gets released. Will dismantling the UGF cause the tank to recycle?

Yes right....but if you siphon out the gunk daily.. it will not require dismantling....
