My usual brush cleanser is the MAC brush cleanser. It does the job fairly well so I'm on my 2nd or 3rd bottle already, haven't thought of switching.
Then I saw the new Bobbi Brown brush cleansing spray- which is meant to be used to keep your brushes clean between regular washes. e.g. if you used your blush brush, then decided you wanted to apply another blush color in the next 5minutes- but your brush is dirty, what do you do?
Bobbi Brown brush cleasning spray- simply spray a few spritz on a clean tissue (or kitchen paper towels are better I think...because they have less fluff). Then brush your dirty brush over the paper towel, until no more color comes off.
Here's back of box- it say sit's alcohol-free, spray formula designed to clean brushes instantly between makeup applications. You can use it for both natural and synthetic brushes.
Here goes the test- two brushes- one is Calvin Klein powder brush (limited edition- unavailable now), the other is Sonia Kashuk skunk brush (not fantastic- but they are cheap and works with pigmented blushes, so I have 2 of them so I don't have to keep cleaning my brushes). You can see they both need some clean- especially the original white tip of the skunk brush needs some clean as it's now stained pink.
Both of these brushes are synethic bristles.
Here's the after- the top tissue is clean, bottom tissue was sprayed with 3 spritz of the Bobbi Brown brush cleansing spray, then I just swiped the dirty brushes over the tissue on the bottom 5 or 6 times each.
Any traces of blush powder or color comes right off.
You can see the color stays on the bottom tissue now (compared to the new tissue on the top).
Here are the brushes after cleaning. Honestly they look as good as if I did a proper wash in water then airdry, with MAC brush cleanser.
Probably need to use kitchen paper towel next time, as tissues have some fluff so it's picked up in the picture below on the left brush (not because there's any residue left on the bristles).
But you can see how clean the skunk brush is, the bristle restored to white. They are pretty much instantaneously dry. I still swipe a few more times on a clean tissue just to make sure any remaining cleansing spray is removed, after all the brush comes in direct contact with your skin.
It's 3.38fl oz or 100ml, which must last for ages!
Only issue I might mention is, even though the bottle is not aerosol or pressurized can, I ordered this from overseas and during transit I think there was some minor liquid seeping out (the bottle was in tact and no further spillage experienced). So I'd assume the bottle is not fully air tight so pressure during air transit probably just forced some liquid out.
It does the job, while it shouldn't replace a full brush clean, it's great for inbetween cleans. I can imagine it works wonders for those people who use several eyeshadow brushes from day to day. This would make life very easy!
