Oven Mate Deep Clean Oven Cleaning Kit has been voted No 1 best oven cleaners to buy

The kit includes a 500ml bottle of oven gel (enough for two cleaning sessions), a bottle of rack-cleaning solution, two ridged scourers, two packets of 25 microwave steam clean wipes, two pairs of long rubber gloves and a gel applicator brush.

To clean the oven cavity, simply paint the gel onto the interior walls and floor (avoid catalytic liners and make sure the oven is cold) and leave it for an hour or so to do its thing. In the meantime, put the racks into one of the supplied plastic bags and pour in the solution. Swish it around, seal the bag and go make a cup of tea. Finally, wipe the gel away from the inside of the oven and prepare to be amazed at the transformation - this stuff really does work astonishingly well.
