Renting a tile & grout cleaning machine:
If you were to check the statistics of this website you would find that the NUMBER ONE key word search for this website is: "Renting A Tile & Grout Cleaning Machine." People come here daily, people email us, and even call us wanting to know where the can rent a tile & grout cleaning machine. Often times we get questions about wether you can use a Rug Doctor or a Bissell carpet cleaning machine to clean tile & grout. Most of the people who contact us are DIYers (Do IT Yourself) and they have already tried scrubbing with a brush, using bleach, acid, etc. with little or no results.
There is more than one way to clean & grout. The obvious way is to get on to your hands and knees and scrub the grout lines and tile with a stiff nylon brush and vacuum up the water with a WetVac. Some people have actually started this process only to learn that it is extremely difficult, time consuming, back breaking work. Unfortunately renting a carpet cleaning device like a Rug Doctor or a Bissell will NOT work, and here's the reason why:
When cleaning carpet you are using a chemical that has a pH level of 8.0 to 9.0. When cleaning tile & grout you are cleaning with a chemical with a pH level of 12.0 or higher. Since pH is measured in powers of 10 this makes tile & grout cleaning solutions at least 10,000 times the pH as carpet cleaning solutions. Because of this high pH the floor must be thoroughly rinsed or it can damage the color in the grout, attract new dirt at a rapid pace, etc. In order to properly rinse we here at Liberty Floor Solutions rinse the floor using 2.2 gallons of hot steamy water per minute with a psi (pounds per square inch) of approximately 1,200. If you have ever rented a Rug Doctor their fresh water box is about (1) gallon and the psi is about 50. This means that the Rug Doctor and the Bissell are using much less water. It is the high pressure that safely loosens this 'yuk' from the porous grout making for an efficient removal. It is not uncommon for a tile & grout floor to look almost new once we have completed the task.
In order to generate the amount of water heat (our temps are about 210 degrees), water pressure, and vacuum ability you would need an energy source - a Truck Mounted Engine. Our truck mounted engine has been specifically designed to clean tile & grout floors. Our hand tools have been specifically designed for that purpose too.
If you are intent on trying a Rug Doctor on your tile and grout floor my advice to yo would be to make sure that you have some carpet to clean too. When the grout cleaning fails you can use it on the carpets. Don't forget to use ONLY carpet cleaning solutions on carpet. I hope this blog has been helpful to you. If you have a question please let me know.
