Frequently asked questions

What is the best carpet cleaning method?

For periodic deep cleaning, hot-water extraction is widely recommended. Interim methods suit fast maintenance.

Is carpet shampooing still used?

Rarely; it tends to leave residue and has largely been replaced.

What is encapsulation?

A low-moisture method where polymers trap soil that's vacuumed away later.

Which method do you use?

Truck-mounted hot-water extraction.

Can methods be combined?

Yes; many commercial programs use interim methods between deep extractions.
