50:50 71% alcohol:water. Spray and let evaporate.

avoid anything with ammonia

I typically only use soap and water on my quartz counters, but have been wiping with rubbing alcohol these days.

After washing with a rag and soap/water, I always used a combination of alcohol and water (50/50). We are now using straight 70% isotopic alcohol. I spray it on and let sit.

According to this article good old soap and water works just fine.

After handling raw meat over the counter I use chlorox cleaner with bleach. It has never damaged any granite I have owned, or my current Taj Mahal quartzite and quartz.

Test your material first to confirm it can handle any cleaner you try.

I use Clorox wipes but I have no idea if they have bleach. I don't use them to disinfect, but to clean the stove area and microwave. I'll do a section of granite if I see grease on it.

Why do you want to disinfect your counters? Other than meat touching them, is there anything else that could be infecting the countertops?

I’m just thinking about more thorough cleaning since I bring things home from the grocery store that have been handled by others. My new rule is that nothing should come into the house and land on the kitchen counter - leave it in the laundry area. We aren’t all 100% with this yet however. It sounds like continuing with soap and water may be fine.

I've used the orange citrus Clorox wipes on our granite just fine.

Either straight alcohol or bleach water solution. I have been disinfecting several times a day as I place things on the counter or after I have prepared food. I have been walking outside and am afraid of spreading anything inside.

Good idea! It's been a week since we bought groceries. I'll probably lay a sheet on the counter and wear my disposable gloves to put food away. And wash my hands. :)

DH is headed to the store early tomorrow morning. I told him when he brings in the bags (ours) to put them on the floor instead of the counter. I read in the WaPo it’s not necessary to wipe down what you buy before putting away—-just wash hands well when finished.

I have nice sturdy reusable bags and after going to a couple of markets today, I threw the bags in the wash and will try to wash them more regularly.

For disinfecting I use green alcohol (smells better) in a spray bottle or Clorox wipes. I use Granite Gold spray when I am just cleaning usual debris.

Oakley, disinfecting your kitchen counters is kind of like washing your hands. Anything brought into your house has germs. I don't prepare meat directly on my counters, but I disinfect almost daily. It's just part of my clean-up each day. Clean sink, put everything away, etc. and wipe counters. I have quartz. I use method or mrs. meyers for a nice scent or bleach wipes, alcohol (also on my cooktop), thieves cleaner, or bleach/water mixture. Years ago I attended a class at work for CE points and it was on controlling germs in the home. One thing has stuck in my mind - they taught that whatever disinfectant you use, spray it on the counters, then leave on a few minutes before wiping off.

From moving into the house, we have always used straight alcohol, minimum of 70%.

ETA: If you use a bleach solution, be aware that it will still bleach clothing. The Grands preschool uses a bleach solution and all of their school clothes have bleach streaks on them where they have leaned into a freshly disinfected table.
