If in doubt, I think its better to use too much product rather than not enough. If you load up too much soap, you can always add more water easier than taking soap off the brush.How long will rotate the brush in the soap? Sometimes I think little time (20 seconds) so I'm not much foam. 1 minutes would be ideal or waste?
Use a badger brush and shaving soap Tabac.
