Vulpex liquid soap is a safe cleaner for practically everything from paper to stone.
Since its introduction in 1970, its extraordinary versatility has made Vulpex a popular and indispensable medium in all branches of professional restoration and conservation of fine art objects and historic property.
It has been used with eminent success in the safe and controllable cleaning of materials ranging from feathers, costumery, leather, carpets and furniture to oil paintings, armour, precious metals, shell, marble and stone.
Vulpex attacks and emulsifies dirt, fats, fatty oils, mineral oils, waxes and hydrocarbons with great speed and efficiency. The dirty emulsions are remarkably stable, thus easily disposable. Micro-fine cracks harbouring dirt are subject to a deep-cleansing action rarely achieved with normal commercial cleaners.
Compared with harsh, acid-based cleaners, alkaline Vulpex is not harmful to health or property. A final rinse or wipe with clean water neutralises the surface, leaving behind nothing to create future conservation problems.
When the job demands a non-aqueous cleaning system (for example, when removing grime from leather), Vulpex uniquely can be blended with mineral spirit (paint thinner/white spirit) instead of water.
Vulpex is supplied as a dense concentrate and must be diluted before use. For normal aqueous cleaning, one part Vulpex to six or seven parts cold tap water (by volume) is sufficient. More water can be added if the soiling is light. As a spirit soap, one part Vulpex in ten to twenty parts solvent will be found effective.
Since Vulpex is a highly effective de-greasant, hands should be protected against the loss of natural oils by wearing gloves or the subsequent use of a lanolin hand-cream. Eyes should be protected from splashes.
Vulpex is concentrated and must be used in diluted form.
Vulpex Spirit Soap is supplied as a dense concentrate form, which needs to be diluted before use.
Dilution ratios differ according to whether diluting with water or diluting with white spirit.
To start with '1' part Vulpex soap to '6 - 7' parts water (by volume) is recommended. More water can be added if the soiling is light.
As a spirit soap, '1' part Vulpex in '10 - 20' parts solvent will be found effective. Normally, only a few seconds of scrubbing or rubbing will be enough to break up and dissolve grime films. Adjust dilution accordingly. (A sign of poor dilution is that a greasy like residue will remain on the surface after application, being the solids content of Vulpex).
A final rinse or wipe-over with clean water completes the job, leaving nothing behind to create future conservation problems. Dirty Vulpex solutions need not be discarded; the solution remains highly active for months even though highly charged with emulsified grime. In cold weather separation may occur, shake container vigorously to eradicate and the efficiency of Vulpex are not diminished because it appears more or less viscous.
As with all conservation applications it is important to ensure complete compatibility with the substrate being treated and any chemicals that may be applied as part of the ongoing preservation of the item. Any traces of the cleaning agent should be carefully removed from the surface of the treatment area before applying further chemicals thereby reducing the possibility of any adverse chemical reaction.
Vulpex concentrate keeps perfectly for several years. Store at room temperature. In winter site conditions, if gelling or separation occurs, the concentrate in its container should be warmed in hot water or by a radiator until the soap re-liquifies , before diluting with water.
