Just bought an old house, where the vendors replaced the doors of the kitchen cupboards, which are lovely and modern. However, the carcasses are really discolured and yellowed inside. Also, they smell quite musty. Don't want to replace the kitchen due to hassle and expense, as it is quite a large kitchen, also, I like the new kitchen doors, but has anyone any suggestion how I can whiten and clean the inside of the cupboards, or can I cover them with anything? Also, what would get rid of the smell? Any advice greatly appreciated.
