Hopefully, your kitchen worktops (countertops) and units are the ultimate in hard-wearing, able to withstand strong and effective cleaning. But you can’t guarantee it for a fact.
Many kitchens are designed to look wonderful but their ability to withstand a good cleaning is way down on the list. If you can't identify a surface, err with caution and avoid bleach. This means checking all bottles of multi-surface cleaner, as many include bleach as an ingredient. For sheer speed, it can be tempting to zap the same product on every surface in the room, but only surfaces that come into direct contact with food need antibacterial protection. A standard multi-purpose spray, which is cheaper and may have more stain-shifting power, is the better choice for other areas. The worktops that you prepare and perhaps eat your food on need to be kept as hygienically clean as possible. Be sure to choose an antibacterial cleaner, rather than a simple antibacterial spray. Sprays are designed to disinfect freshly cleaned surfaces. Using them on small areas such as telephone key pads or toilet handles is fine, but why make twice the work for yourself in the kitchen, when you're covering large areas.
It's easy to neglect cupboard and drawer fronts during your regular cleaning session. Yet frequent attention makes your kitchen look smart and inviting.
