Manufactured by Active, the company behind a super-popular easy toilet bowl cleaner, this formula is highly concentrated.

According to its many supporters, the cleaner successfully tackles stains and black mold on tile grout, caulking, and gasket seals in appliances like washing machines.
Restoring Surfaces to "Like New" Condition
The product is so effective that several reviewers report it prevented them from needing to replace costly items like shower stalls and grout. They claim it restored surfaces to "like new" conditions while also providing a barrier against mold recurrence.
"Had these stubborn mildew stains in the caulking of our shower that no matter how much bleaching and scrubbing I did, it would not come out," explained one reviewer. "Saw this and had to try it. Worked like a charm."
Another user exclaimed, "Literally magic. It removed the stuck-on stained green mildew/mold from the seal on my washer literally overnight. My washer is so clean! Not a factory reset but pretty good for being an almost 10-year-old front loader."

"I got this about almost two years ago now, and I live in Wisconsin and got the weird mold on the windows because of moisture. Let me say I have new windows and they're brand new. You get moisture based on the humidity in your house and just conditions. Once you get that mold it's hard to get rid of. I used this stuff and 'boom' It is GONE. I also use it by the kitchen sink now and mold was GONE! no joke. Wish I discovered this years ago." — Mark and Julie in Waukesha
"This removed all the mold from my washer rubber. We moved into a house where the appliances had been neglected for years and there was a thick layer of mold in the washer rubber that I never thought I'd get it out. I needed to apply this about twice or three times in each area to completely remove the mold, but you don't even need to scrub it - you just leave it there and it does its magic. The rubber looks like brand new, it's unbelievable. I wish I took before pictures to show the difference." — Thais G.
"Too bad I can't rate this for 10 stars. This absolutely amazing product changed the look of my master shower; it looks and feels brand spanking new!!! I was so impressed with the results that I decided to try the application on another shower tub in my house, and it worked fabulously there as well. I wish this came in larger bottles. Definitely buying more." – Cristobal Aybar
"We live in an older house that is a rental. The bathtub/shower has always had dark mildew stains on the caulk and grout. Years of spraying and scrubbing with other leading brand mold & mildew products plus bleach and all sorts of DIY recipes worked fine on keeping grout fairly clean, but nothing worked on the caulk. I tried this product not expecting much, but IT WORKED! I applied the gel and left it on all day, then wiped it off 7 or 8 hours later and the grayish discoloration that had been there for years was finally gone! I was shocked and thrilled. HIGHLY RECOMMEND! I didn't notice any unpleasant fumes (I did close the bathroom door and left the window open anyway) I am going to try their washing machine product next." – l rishel-marzban

Cordless vacuums revolutionize convenience and ease of use. This reader-loved luxury option from Dyson transforms into a small handheld vacuum for stairs, cars, or countertops and can easily reach ceilings, baseboards, and other difficult areas. A single charge provides 40 minutes of cleaning time with famously strong suction.
Promising review: "This is a 'must have' vacuum. I can't believe I've been lugging around a heavy vacuum and a cord for years! The suction is terrific and the first time I used it, it wasn't even on max suction and did a fantastic job. First time I used it the debris canister was so full I couldn't believe I had thought my house was clean. Anyway, it's lightweight. I'm 69, have had back surgery and this is easy for me to use. My daughter and daughter in law have one and I was sold. I got this model because it empties the original way. The newer models require detaching attachments to empty. Research it. I am extremely pleased." — Harvey

And I am so happy with my new Little Green. I can't believe I waited this long to buy it. I've had my Little Green about a month now and I use it probably 2-3 times a week. I just got a new puppy and it is no problem cleaning up his messes and I know it's clean and not soaked into my rugs and carpet. I love that I can keep the clean water tank full so that it is ready at a moments notice for a quick clean up and all I have to do is plug it in and zip/zap the cleaning is done." — Michelle S.
