Sanitation eliminates micro-organisms but it does not remove the spores that can facilitate their production. This neutral odour, vegetable-based Carbon Brush Soap, and the accompanying scrubbing mat, rids brushes of spores to inhibit microbial growth. It eliminates dirt and grime, whilst activated carbon acts like a sponge to absorb the build-up of heavy metals from cosmetics. The Carbon Brush Soap is ideal for a weekly deep clean to keep your makeup brush collection free from dirt, heavy metals, spores and microbes. Guarantee hygienically clean brushes with the ISOCLEAN Brush Cleaning Regime.
