Now, the non-deleterious mutations may have an effect on the certain details in the physiology of the animal, or on its functionality, or may have no effect at all.
When lots of these mutations build up.... if they have caused sufficient changes in physiology, they may give rise to a new species, or just a new race.
If one of them becomes deleterious, it is weeded out of the population, at the same rate as all deleterious mutations. But the overall population retains the non-deleterious ones and just goes on.
Do remember, we are not talking about one single animal from a given species. We are talking about an entire population. And the mutations pop up on single animals, not on the whole population at the same time!
We can agree that the deleterious mutations are weeded out.
But the remainder of the population is accumulating non-deleterious mutations.
If the population does not accumulate these changes, then there is not enough changes in the DNA to turn one species into another.
Now here is the problem. Unless it can be shown that there is enough that are beneficial, the rest do corrupt the genome of the species.
It is speculation that there are enough beneficial changes to produce new functionality.
That is another weakness in the theory of evolution.
Well first you have to define what you mean by a corrupted genome?
You see around 95% of the human genome is junk and that number is fairly in every mammalian genome we have mapped.
I think something that may help understand better is the experiments done by Dmitri Belyeav, I'll link

To-morrow, and to-morrow, and to-morrow,
Creeps in this petty pace from day to day,
To the last syllable of recorded time;
And all our yesterdays have lighted fools
The way to dusty death. Out, out, brief candle!
Life's but a walking shadow, a poor player,
That struts and frets his hour upon the stage,
And then is heard no more. It is a tale
Told by an idiot, full of sound and fury,
Signifying nothing.
