Touch-n-Flow System is a 3-piece set including the popular Touch-n-Flow applicator, applicator squeeze bottle and Plast-i-Weld liquid solvent cement. Use of the squeeze bottle makes a convenient way to fill and empty the Touch-N Flow applicator.
How to clean
As the Plast I Weld is a solvent all you need to do is place the needle in the bottle for a few seconds and this should clean the tip.
If still stuck, put the glass end of the TnF in the filler bottle, place the needle end in the PiW and carefully squeeze and let go of the bottle.
This will clear any debris. Never be tempted to suck or blow with the TnF in the mouth, the solvent is toxic.
