Ensure your filter is thoroughly clean and dry before you start.
Spray the filter liberally with Liquid Power. Make sure the filter is completely covered with a uniform blue layer.
Massage the filter thoroughly (wear protective or disposable gloves) for as long as necessary to have the Liquid Power penetrating deeply into the filter material. For this purpose also a plastic bag can be used. Put the filter in the plastic bag and massage thoroughly.
As soon as the filter is uniformly blue leave it to dry in a well-ventilated area, preferably outside in the open air, under a piece of cloth. This way the solvent can evaporate.
After approx. 2 hours the filter is ready to be used.
Store already oiled filters in a plastic bag and in principle they do not have an expiry date.
