If you find it is unpleasant to use then try the following, if it does not work you can buy yourself a new keyboard so nothing to lose.
Place the keyboard in a bowl of warm soapy water, scrub well with a soft brush then rinse. Shake out as much water as you can and use a hairdryer to dry as much as poss. Place in a warm place, [Airing cupboard] overnight and make sure it is absolutely dry before plugging back in.
It worked for me with a cheep keyboard last year after spilling coffee all over it. I bought a new decent keyboard but still have the other one as a backup, it works perfect.
not really if you know your qwerty off my heart,someone in school took the keys out,re-aranged them so they said naughty words - and Sethhaniel - don't you dare phone my IT teacher and say it was me,it wasn't.
