I use greased lighting for all my cleanup.
spray it on and watch the grease roll off.
no scrubing needed just wipeoff with a damp soft cloth. works great on rack holders also.
since i clean comm. exhaust hoods for a living i have found this to be the best cleaner for the money. make sure to rince well.
im sure you will find this to be a lot easier and faster way to clean your racks
