Re-using Scent Wicks

Does anyone out there wash re-use there scent wicks? I plan on using scent this weekend and wanted too hear everyones thoughts on washing and reusing scent wicks. I have a shoebox FULL of wick s from years past and im boarder line ready too throw them out. I normally buy new every year and they are cheap enough. But why not save a few $ a year and try reusing them??

Could just use cotton balls and throw them away after each use....

ive tried just boiling them in water then drying um out and then soaking them in scent killer and drying them, I cant say if it works or doesn't though.
