Today i cleaned a stairs and landing in Heysahm. First using the Kirby Vac to give the stairs a good vacuum, and as you can see it is a versatile machine and with the dirt meter attachment i could check just how much dry soil was in the carpet. Then i used a wool safe Pre-Spray, mechanical and hand agitation to help release dirt from the carpet. After the appropriate dwell time i used hot water extraction with an acidic rinse to leave the carpet at the right ph. The customer said the landing and stairs look like it did when it was first fitted.
