How to clean project before each build?

Is there a way (possibly using schemes) in Xcode to specify that a clean is automatically done before doing a new build.?

I have a project that sometimes fails to build unless I do a clean first, currently I am doing it by hand.

The selected answer did not work for me, it caused my build to fail (Xcode 4.6.3) when trying to run on the simulator.
Based on Jano's answer and on this link in the Pre-action script instead of writing 

rm -rf ${BUILT_PRODUCTS_DIR}

I wrote 

touch ${BUILT_PRODUCTS_DIR}

This should have the same effect and it doesn't cause my build to fail

Press ⌥⌘R, expand the selected scheme, select Pre-actions, click +, select New Run Script Action, set Provide Build Settings from to your target. In the box below type rm -rf ${BUILT_PRODUCTS_DIR}. Note: it is BUILT not BUILD as seen in the Xcode dialog. You can type echo ${BUILT_PRODUCTS_DIR} > ~/Desktop/log.txt to see what's going to be deleted.
