In what way are they 'clearly more effective'? Maybe the abrasion has removed the finish on the leathers you have cleaned which would leave the leather looking much brighter and very clean but will leave the leather unfinished which long term will be very harmful.
Of course we have tried them, we are sent products to try all the time and if we found anything which was so good we would gladly offer it as a solution but as yet microsplitters have proved to be not as effective and possibly in some circumstances damaging.
Shaun thanks for the clarification, they do as the foaming mechanism makes the cleaners very soft. One other problem with microsplitters if you spray them on is the potential for runs which can be impossible to remedy.
