Rug Doctor is a leading manufacturer of carpet cleaning machines. On Rug Doctor's manufacturer directions, it states to only use Rug Doctor cleaning products. If, however, you have concerns over using chemical cleaning products, you may not want to do this, even if it may void your warranty. Fortunately, there are two easy methods of cleaning your rugs with natural and homemade cleaners that will do just a good of a job as Rug Doctor's cleaners.
When you use Rug Doctor's carpet cleaning solution on your carpets, the cleaning chemicals will get into your rug, but will not properly rinsed. The solution stays in the carpet, which may not be healthy for small children, especially babies who lay and play on the floor. Also, cleaning solutions left in your rug can cause your carpet to become dirtier after you're done cleaning them, since dirt can be more easily trapped in by the remaining solution. For these reasons, you can use plain hot water in your Rug Doctor. Simply fill the reservoir tank with hot water and use as directed. This will get rid of most of your dirt and even stains, without leaving any cleaning chemical residue or fumes. It should also not affect your warranty.
Water may not be enough of rid your carpet of some stains and smells, like pet urine. In the Rug Doctor carpet cleaner, you can pour 1 cup of vinegar in the reservoir tank. Then, fill the rest of the way with hot water. This vinegar and water mixture should get your carpet looking new and smelling fresh. To add a pleasant scent to the mixture, you add a couple drops of essential oils, which are natural extracts from plants. They are available at most craft store or where candles are sold.
