I don’t even make any special mixes, just keep containers of the ingredients on hand in bathroom and kitchen. Cheaper too than using specialized stuff.
I do use Barkeepers’ Friend for stained porcelain, nothing else does it except the stuff that bothers my asthma/sensitivies. It still smells awful but not as bad as Comet/Ajax etc.
Do you think barkeepers friend or bon ami are better? Or are they for different materials?
