What the industry recommends
The Carpet and Rug Institute (CRI), the industry trade body, says to have carpets professionally deep cleaned every 12 to 18 months with a CRI Seal of Approval service provider. It also calls weekly vacuuming with a CRI-certified vacuum a good place to start.
Manufacturers give a wider range. Shaw, a major carpet maker, says to schedule a professional hot water extraction anywhere from 6 to 18 months, depending on traffic. So the sources differ at the low end, and neither claims one interval fits every home.
A practical reading: treat 12 to 18 months as the upper limit for average use, then move earlier as traffic, pets and children go up. That last step is our reading of the guidance, not a number either source gives.
Households that need it sooner
CRI sets vacuuming by traffic: high-traffic or pet areas daily, medium-traffic areas about twice a week, and light-traffic areas once a week. A room that needs that much upkeep is a natural candidate for the shorter end of Shaw's range.
- Pets: hair, dander and outdoor dirt arrive on four paws, and CRI puts pet areas in its daily vacuuming group.
- Young children: spills happen at floor level. CRI's advice for them is to scoop up solids and blot liquids, not scrub.
- Allergies: National Jewish Health lists frequent vacuuming of rugs and carpets among its dust mite measures, adds that a person with a dust mite allergy should not vacuum or be in the room, and suggests washable area rugs instead of carpet in the bedroom. CRI says carpet that is cleaned regularly is fine for people with allergies and even asthma, but it is an industry body, so your doctor should guide any allergy plan.
Our guide on whether steam kills dust mites covers the lab studies behind that last point.
High-traffic zones and area rugs
Soil collects where people walk: entrances, hallways, stairs and the path from the kitchen to the sofa. CRI says removing soil while it is still on the surface, before it gets tramped down, is the first and most important step in carpet maintenance. You do not have to put the whole house on one schedule. A front hall can be due long before a spare bedroom.
Area rugs follow the same logic, and the ones by the door pick up the most. Check the rug's care label or ask its maker first, because construction and dyes vary and some rugs should not be wet cleaned.
Signs it is due
- Darker, flatter lanes of pile along hallways and in front of the sofa.
- A smell that comes back soon after vacuuming.
- A gritty or matted entrance that the vacuum no longer lifts.
- Old spills that have been blotted but still show.
- More than a year since the last deep clean in a busy household.
None of these is a diagnosis. They are prompts to look closer, with the interval above as your backstop.
Why residue-free cleaning matters
What a cleaning leaves behind matters as much as what it takes out. CRI's spot removal guidance warns that many spot removal solutions leave residues in the carpet that may attract soil, and says thorough rinsing is necessary to remove detergent residues that may cause rapid soiling. Anything left in the pile can pull dirt back in.
Water matters too. Health Canada says mould will begin to grow in an area with excessive moisture within 48 hours, so a method that soaks the carpet carries its own cost if the pile stays wet. Steam uses very little water and no detergent, which is why we use it. Whatever method you choose, ask what stays behind and how the carpet will be dried.
Between deep cleans
- Vacuum on the CRI schedule for your traffic level.
- Scoop up solids and blot liquids with a dry, white cloth or paper towel, from the edge of the spot toward the centre. CRI says not to scrub.
- Put a mat at each entrance so soil is stopped before it reaches the pile.
- Deep clean the busiest zones first when you are not sure the whole house is due.
Where Steam Shines fits
Our carpet and rug cleaning covers living room and bedroom carpet, hallways and stairs, area rugs and runners, with extra attention on heavily walked areas such as hallways and entrances. We use high-temperature steam and microfibre, with no harsh chemicals and no detergent left in the pile. It kills dust mites and bacteria on contact. Delicate rugs get a lower-moisture setting, and we tell you what to expect before we start. Carpets and rugs are safe for kids and pets as soon as they are dry. Upholstery gets the same steam in our sofa and mattress cleaning.
We come to you in places like Mississauga and Milton, and all we need is access and a standard power outlet nearby. To ask about a particular carpet or rug, message us.
