It may be that it is because of the composition of my sweat, but T-shirts and short shirts I could with regular use of the Deo's use (usually with aluminum chloral hydrate) for almost a year as a swab.
Now I have here a "big package" 6 Deo's worried and want to summarize briefly.
The Fragrance - I got used to it. BUT, my T-shirts, whether white, black or colored have no spots more.
So I have now found my deodorant and will continue using it.
