- Dust before you vacuum, work top to bottom, and wipe dust dry before spraying.
- Cleaning, sanitizing and disinfecting are different levels, and disinfectants need contact time.
- Never mix bleach with ammonia or vinegar, and do not use vinegar on stone or wood.
These are the questions we hear most often. Answers are short, with a note on how things change in a workplace. Where a topic has its own guide, we link it.
1. Should I dust or vacuum first?
Dust first, then vacuum. Dusting knocks particles loose, and they settle on the floor. Work top to bottom so each surface is cleaned only once. Details: dust or vacuum first.
2. What is the difference between cleaning, sanitizing and disinfecting?
- Cleaning removes visible dirt, dust and debris.
- Sanitizing lowers the number of germs to a level considered safe by public health standards.
- Disinfecting uses an approved chemical to kill germs on a surface, and the product must stay wet for its labeled contact time.
Clean first, then disinfect. See disinfection basics.
3. What is the number one cleaning mistake?
Spraying cleaner on a dusty surface. It makes a muddy film that gets pushed around. Wipe dust away dry, then spray and wipe.
4. What is the dirtiest spot?
Often not the toilet. Wet, food-rich places such as the kitchen sink and sponge are usually germier. Replace sponges every one to two weeks. See break-room germ hot spots.
5. How do I remove hard water stains from glass?
Spray equal parts white vinegar and dish soap, let it sit 15 to 20 minutes, scrub gently and rinse. Keep it off stone and metal trim. Details: vinegar do's and don'ts.
6. Can vinegar clean everything?
No. It works well on glass and mineral buildup, but it can dull or etch natural stone and damage some wood finishes. It is also not a disinfectant.
7. How often should sheets, towels and mattresses be cleaned?
Typical home guidance: sheets weekly, bath towels every three to four uses if they dry fully, and mattresses vacuumed and freshened about every six months. Hotels, rentals and healthcare settings follow their own policies and local rules, usually changing linens between guests or on a set schedule. Check the rules that apply to your property.
8. What is the secret to cleaning quickly?
Carry everything in one caddy, follow one route (top to bottom, one direction) and use a checklist. Professional crews use the same method in every building.
9. Why does my dishwasher or washing machine smell?
Trapped moisture, soap scum and food particles grow mold. Clean the filter weekly, run a hot empty cycle monthly with a machine cleaner (or vinegar if the manufacturer allows it) and leave the door ajar to dry.
10. Which chemicals should never be mixed?
Never mix bleach with ammonia or with acids such as vinegar. Both create toxic gas. Use one product at a time, ventilate, and follow the label. Full guide: chemicals you should never mix.
When the answer is "call a professional"
A written scope, trained staff, the right products for each surface and a repeatable checklist are what separate a one-time clean-up from consistent results. See what's included in commercial cleaning services.
This article gives general cleaning information. Follow product labels, manufacturer instructions and the rules that apply to your property.
