Recommended Cleaning


Step 1. 

Use warm soapy water, our Spit-Spot-Bit-Pot and our Willow Brass Brush to remove the dust and product debris from within the grits, flutes and teeth. Alternatively, put them into your Ultra Sonic Cleaner with some detergent on the relevant cycle. 


Step 2. 

Now it's time for your preferred disinfecting or sterilising method. We recommend our "Willow Spray & Go 2 in 1" system as the less time your bits spend immersed in solution, the better! Lay your E-file bits on a towel and evenly spray, role them over & spray again. If you are using a soaking system please only steep for the recommended time only, over-steeping will dull your E-file bits.


Step 3.

Wait 2 mins and then dry all of your bits thoroughly by hand (do not leave to  air dry). Store in your bit case or bit book.


How do I know when I need a new bit?

If the bit you are using originally took 1-2 swipes along the nail to penetrate the product and now is taking 2,3+then it's now time for a new piece. Your removal will take longer & you will start to feel physical wear and tear on your body.
