you can, but why waste a good mf towel applying smr? Id suggest getting some terry applicators or towels and using those since they are cheaper and can be washed out easier. With an mf, youd get product stuck into the fibers bc of all the excess. Im sure a lot of ppl have done it on here, but Im just giving you my opinion from my own personal experience.
Agreed, althought i dont think your wasting the MF, why even get it dirty, go with an old terry sock......Cut the "tube" off and use the toes part....If your going with SMR, and by hand, your going to need all the help you can, go with terry.......
