Many cleaning techniques are surface level. If you want to reach dirt embedded deep within your carpet, you may need a different approach. Steam-cleaning is one potential option.
Clear the Area
You should move furniture and anything else that could be an obstruction out of the room. If this is not possible, wrap the legs in plastic film, foil or wax paper as protection from moisture. Then perform your regular cleaning tasks such as dusting, vacuuming and applying stain remover.
Prepare the Steam Cleaner
Every steam cleaner will have its own instructions, so ensure you read and follow them carefully. Generally, the first stage is to fill the steam cleaner to its maximum level with water. Most cleaners do have a heating function, but using already-hot water can save time. Then you can add detergent, again at the specified level. There may be a recommended detergent, but you can also use white vinegar.
Apply Steam Cleaner to Carpet
Start in the corner furthest from the door and move your cleaner slowly in a straight line across your carpet. The usual process is to squeeze the handle to release the water and detergent, then go over the same area again, this time squeezing to suck up water and dirt. Keep slowly and methodically pushing and pulling over the same area until the water runs clear. Turn and cover another straight line in the other direction, overlapping the first slightly to ensure nothing is missed. If your tank becomes full of dirty water, empty and refill it.
Aftercare
Do not walk on the cleaned floor unless unavoidable. If it becomes necessary, do so barefoot. Do not replace the furniture until the floor is completely dry. Baking soda can help speed up the drying process.
Of course, if you are uncomfortable doing this yourself, you could hire professionals such as those at https://intocleaning.co.uk/contract-cleaning/industrial-cleaning-gloucestershire/steam-cleaner to apply their own industrial steam cleaner.
Steam-cleaning is an effective way to remove deep-rooted stains and dirt in your carpets, when performed correctly. Ensure you follow the instructions, or hire a professional.
