The product itself is fine at cleaning brushes, however user beware as the formula has a very strange slippery and oily feel, which does not remove itself too easily if accidentally sprayed onto surfaces. I bought this thinking it would be just like the cinema secrets cleaner, where you can quickly spray onto your brushes directly and wipe onto a tissue. However, when this product is sprayed into the air, it leaves this weird residue on every surface and carpet which is extremely difficult to wipe off and makes everything slippery and greasy to the touch. So it would be best to spray this onto a towel or tissue directly so there is no chance of it ever going onto your surfaces. Also, this product is not travel friendly at all and leaks badly. It leaked on its way to me in the post and has leaked since I began using it. I have had to tip it into another pump bottle in order to take it around with me. Unfortunately not worth the effort in my opinion - spend a little extra on cinema secrets and save yourself the hassle!
