you cant be sure that it would
only contain dust unless it was tested..my bet it would also contain some debris and level of bacteria also...ready to transfer to the next client.
Thorough handwashing by the client..15-20 seconds, using a clean scrubbing brush under the nails...same time again for rinsing..using a fresh towel for drying will keep the bacteria down before service..couple that with a hand sanitiser...but unless this is
always being performed before each and every service properly you cant possibly have clean oil..and even then you cant be sure?
Just hand sanitiser (unless you are packing it under the nails) wont get rid of any nasties that lurk under neath the nail.
During the pre shape and blending away any lifting will spread bacteria about..so i guess even a thorough handwashing wont reach anything under lifted product prior to service..which will be cleaned with scrubfresh but you have dusted first..which will leave a amount of possible bacteria in your dusting brush.
Who knows what clients nails have come into contact prior to their appointment..nose picking, making rissoles:lol: scratching their bum?
I dont know why, when given a choice would any one use a brush over a dropper (unless you like to drizzle your oil). Do you think i could possibly have a OCD?:lol:
