i've been using 'normal' bristle brushes for years now and have always had to replace them after a short period, mainly due to the fact that the bristles held onto the smells from the food stuff, especailly liking oils and liquids, which made the bristles go tacky and none usuable, even after soaking, washing, soaking again, everything but actually sandblasting the things.
Anyway, i decided to buy this bristle free brush as it had some good reviews and i'm glad i did.
i have been using it now for a bit and it has been dipped into alsorts of stuff, but unlike the bristle brushes the odour and smells, even the oils i use for covering pastries, just won't stick to these.
The 'rubber' type bristles clean with ease and with them being rubber type the smells and oils just roll off them.
I paid a couple of quid for this and from my experience with it so far it will out last the pricier 'normal' bristle ones that i have used in the passed.
so if you do a lot of cake baking then get one of these, you won't be disappointed one bit
