I'd say no, keep practicing, check out YouTube for some tips, when I first started wfp it also took a little while to understand it, you just need to make sure the top frames are really well scrubbed and rinsed, then give the glass a good old scrub and make sure to rinse well, after a couple of cleans it will then get quicker and quicker as the top frames will have less dirt if any to contaminate the water,
I say just keep practicing!
