Excerpt from: "The ABC's of Conservation"
When cleaning always use as little of the cleaning medium as possible. Dip the swab into to mixture, then roll it on a paper towel to remove excess before applying to surfaces. Use the same care when rinsing with clean water.
The bisque face is gently cleaned with cotton swabs, using one part soap to seven parts water mixture of Orvus WA Paste or Vulpex Liquid Soap. Remove all traces of soap with swabs dipped in clean water. Wear gloves when using Vulpex.
