The housekeeper at a Cambridge College told me about this; it only happened in the new power showers.

This was the other trigger which led us to develop the new Dossil^® Shower Sinkie^® for use in power showers. So, choose this one for use in your power shower.

The Large Dossil^® Shower Sinkie^® was developed to solve this issue.

This happens pre-dominitely in soft water areas, or in artificially softened water. Surfactants in gels and hair shampoos can cause excessive foaming; just think of the foam from waste detergent in those soft water burns, streams and rivers.

This foaming does not dissipate very quickly; however there is an old tip, given to me by my wise octogenarian father; swish a bar of ordinary soap and this will remove foam very quickly.

The holes in the Dossil^® Original are slightly smaller than in the new Dossil^® Sinkie^® Range; and you may find it is best to use a Large Shower Sinkie^®, designed to help this problem.
