First of all, don't spray the bird or cover the bird for screaming (or biting or whatever). Either the spray is gentle and it may just like it, or the spray is strong and hurtful. Yet either way it won't teach the bird not to scream at best and at worst might just encourage it to scream because it earns it at least some attention. The best strategy is to keep the cage someplace where the noise will bother you the least and have the bird out in the main living area during interaction time. If no one is there to acknowledge the screaming, there is no chance of rewarding it (not saying there won't be any but at least it won't encourage more than the typical amount. The typical amount you just have to accept as part of what a parrot is and does).
Also, to the part about how the parrot "hates me although I feed and clean out etc." Don't for a moment think that the parrot owes you one bit of gratitude for doing those things. In the wild, food just appears by itself and there is no cleaning. A bird does its business where it does and it fertilizes the soil. If anything, the plants should be grateful for the birds but I diverge. Point is, it does not see what you are doing as a good thing (although obviously it is necessary for living in a cage and we appreciate that you take care of this). To the parrot, what's important is what you do for it (that it can recognize immediately as beneficial) and your attitude. Doing good things for the parrot is stuff like giving a treat, head scratch, attention, taking it out of the cage, etc. While talking about good things I may as well mention some bad ones that you want to avoid doing (and it's not out of the question that as the cage cleaner you are). Bad things that would make a parrot avoid/bite you could include putting it away in the cage, squirting it painfully, scaring it (like cleaning the cage while it's inside), putting it in a carrier, grooming it, taking it to a vet/groomer, etc. It is often possible that the person that takes care is the person the parrot doesn't like because it doesn't experience these as positive things. Now as for attitude, they'll often appreciate/accept someone who is a bit more strict and won't accept being pushed around. This is especially true for what tend to be the more aggressive species. If they learn that someone can be pushed around by biting, they'll take full advantage. On the other hand when someone isn't afraid and doesn't care about a couple bites, the parrot is more accepting. This doesn't mean to fight back or be cocky, but the combination of fearlessness and doing good stuff for it is the optimal combo.
