Andy, email me your address and I will send you one. Guarentee you wont use any thing else after trying them.
Judy your answers just dont stack up
Kitchen brushes are certainly not dangerous to use on leather unless you are using them to scrub the dirt out.
What else would you use a brush for but to scrub the dirt out. If like you say the chemical does the work then you would not need to agitate with such a hard nylon brush and you would use a softer tampco type brush.
Any way if used correctly these sponges do not remove top coat, if LTT have found that then they are using them wrong.
Judy ask Andy if he wants to come and spend a day with me, and I will educate him on their use
