    5.0 out of 5 stars Works like a charm

    5 year old white grout otherwise very well maintained but minerals in the water started discoloring it , this product brought the grout back to its pristine white color with spraying it on the grout and with very minimal brushing ( sometimes with just wiping along the grout lines with a wet pepper towel after spraying )and minimal odor from the product . it wipes off the tiles very easily too . I highly recommend it !

    Works amazingly well! The brush is perfect for getting into crevices, making cleaning effortless. No bad smell either. Highly recommend!

    Worked well. Comes with stiff brush which aided in the success of use.

    3.0 out of 5 stars Great cleaner. Not so great spray bottle.
    Reviewed in the United States on November 8, 2024
    The cleaner works great, but the bottle is terrible. The sprayer will not stay attached to the bottle. I lost much of the product and it splashed all over me the first time I used it. I reached out to make the first spray and the bottle fell right off onto the floor. So…I know first hand that it has very little odor and it is not caustic. I used both hands to spray the shower after that. It did a great job cleaning the grout and it is actually a great product.

    I always read the reviews but try to take them with a grain of salt: is it really that amazing. This one is. I used it first on a small bathroom floor with white grout-or what used to be white grout. First I noticed that it didn't stink. I am super sensitive to smells and this did not have a smell, not even a perfumy one. Other than the spots where the grout had broken up and patches are needed, it did great. Perfect-probably not but that grout is at least 10 years old. It gets washed and I have tried some other products with no difference. This made a RADICAL difference! So I kept going to the kitchen with dark grey grout. What i liked out there was it cleaned the tile in the tight spots near doors and the stove that get grimy but a swiffer just doesn't do enough for. The grout looked better too. My one complaint is the product seems to leave a soapy residue. I don't own a sponge mop so trying to clean that up was difficult. I would suggest making sure you have a traditional mop of some kind to wash the floor with after. Swiffer won't work.

    Cleaned my shower using this product and it worked excellent. The brush is also a big help for the grout.

    I don’t normally leave reviews. But after using this product, I thought everyone should know how well a job it did. My tile floor grout was looking very dingy and yellow and I thought I would have to re-grout. This product saved me the hassle and I am very happy with the result. Also, I was especially pleased that it did not have a toxic smell. ????

    3.0 out of 5 stars Doesn’t work with a hand brush
    Reviewed in the United States on December 14, 2024
    I tried to clean my bathroom tiles and the grout. It did nothing to clean the grout. It is still the same as it was before. I’m going to try a standing grout brush to see if that makes a difference. But as of now, I’m down $20 something dollars and a very sore hand and wrist from scrubbing so hard. I gave it three stars because I like the smell. Other than that, didn’t work.
