most caera / telescope shops sell lens cleaning fluid or lens wipes or just plain lint free cloths(not many i think use theese)
some of the cloths i have got with chinese gear are terrible and i just throw them away. aust geographic sell a reasonable cloth in a flat disc holder.
Dave without trying to make to much a point on lens cleaning solutions .. hackin up a golly while being really handy at the time probably isn't the best way to go ... though my telrad lenses do cop some fairly sketchy at times so possibly I'm not the best one to comment
