How to clean dirty grout

by | May 2, 2018 | Tile and Grout Cleaning | 0 comments

So how do you get that dirty grout clean? Well first we have to determine if the grout has previously been sealed or not. And if it has, is the sealer still present? We can determine this by performing this simple test. Take a small amount of water and pour it into the grout lines. Watch how the grout responds to the water. If the water is quickly absorbed into the grout then the grout is in an unprotected state. If the water does not absorb into the grout, then the grout is still protected by a sealer. Grout that is sealed responds better to cleaning since dirt and grease is not able to penetrate the grout. Most grout is soiled with household oils and dirt. This type of soil can be effectively cleaned with a degreaser. There are many degreasers that are available to home owners. One that all should be very familiar with is dish detergent. Follow the following steps using dish detergent to get that dirty grout clean again.

  1. Make a solution using 1/2 cup of dish detergent and 1 gallon of water. For extra strength you can boost the solution with 1 cup of Hydrogen Peroxide.
  2. Saturate the floor with the solution and let it dwell for 15 minutes. This allows the solution to emulsify the soils.
  3. Agitate the grout lines with a stiff bristle brush.
  4. Remove solution using a sponge.
  5. Use clear water to rinse the grout.
  6. Repeat steps 1 thru 5 until grout is cleaned as desired.
  7. Allow grout to dry.
  8. Apply penetrating sealer according to instructions on label.
  9. If all above fails (including motivation) – contact a professional for a free estimate!

Very professional company. I called on a Tuesday and my house was cleaned first thing Wednesday morning. Carpet was cleaned thoroughly. House smelled very clean with natural scent. Pricing is definitely within reason. I’d recommend this company to anyone.

Working with Thomas and Takiyah of Revitalize Home Services has been great. They are pleasant and helpful and I look forward to continuing to work with them in the future. After seeing their professional carpet, tile, hardwood floor, and granite counter-top cleaning completed work - I would definitely recommend their services to all my friends and family.

Tom and John are so great!!! Very professional, considerate, and kind!! Have used them now 3x and they do a fantastic job. They even got a blue dye stain out of my bathroom carpet that I was sure couldn't be done. My carpets look brand new. Plus doing such a wonderful job they are very reasonable. Will use them until they retire.😊

Excellent work. I had my carpets cleaned for the second time and once again i was speechless. Exceptional work for a decent price. My carpets were immaculate and the scent left was fresh and clean. I recommend them entirely. Professional work.

I am extremely pleased with this company! Thomas and John have cleaned the ceramic tile and grout in my kitchen twice now, as well as annual sealing of the granite countertops in my kitchen. They are punctual, friendly, and do excellent work for a reasonable price. I also mentioned an ongoing problem with our bathroom sink that two plumbing companies had been unable to fix, and Thomas offered to take a look at it. He quickly identified the issue, obtained the necessary part, fixed it, and charged me a very reasonable price for the repair. I was so impressed -- I had just about given up! I highly recommend this company!

I just had my carpets cleaned by Revitalize Home Services and wow! I wish I had taken "before" photos because they were a real mess. Coffee stains and cat barf spots have now disappeared and the "after" carpet looks brand new! I was not expecting them to come out that good! Thomas and his helper were pleasant and helpful and I look forward to getting them back in once I dirty them up again. I would definitely recommend their services to all my friends and family.

Called on Friday to discuss granite cleaning. Thomas showed up on Monday with help to provide and estimate and allowed me to make an informed decision before proceeding with the work. Very professional and friendly. Will be calling them back for carpet work and routine maintenance on the counter tops.
