X-14 Professional Instant Mildew Stain Remover 32 FL OZ (2 pack)

Ok so if I was at my dads house and could provide a before and after picture of his once frightening bathtub, I would. He has the ultimate bachelor's bathroom , but with an extra grimey twist of mildew and funky funky in the tub. As in I wouldn't shower in hisbshower without flip-flops on.Anywho- this spray will fix the nasty, and with ease. His tub was corroded, so I sprayed quite a bit, opened the windows and split. Came back and his tub looked foreign.Main thing is , its powerful stuff so use caution with use. Open a window- most definitely, the fumes are intense, but that's to be expected with the real deal type chemical that can cut through the thickest of grime & funk. Hands down I'll continue to buy this to keep my dads tub, tile &toilet sparkling clean. It's a winner for sure...

Works wonders on white shower grout.

I used this to remove mold and I was very happy with the results! It does have a very strong smell so if you’re in a confined area only use a little at a time so you can adjust to the odor.

I purchased this after watching my son detail his boat upholstery with it. His boat had been sitting for 2 years, in humid SC, and the upholstery was covered in black mildew spots. His upholstery looks brand new, no spots, bright white again.I bought it to use in a shower that never gets any light, and gets mildew spots quite quickly. No more scrubbing with a pad and scouring agent. I just spray it on, wait 30 minutes and rinse it off.The chemical odor is very strong, so I open a window, close the door and run the exhaust fan, but that's a minor issue.This was recommended by a professional boat detailer, but caution should be taken not to soak the upholstery stitching since it will damage cotton thread.Amazing stuff, but strong.

this stuff was recommended to me by my landlords, and it's actually insane how easily and quickly it worked. I will say - the smell is super chemical-y and bothersome, but it does the job. Sprayed on dark spots in my bathroom and watched them disappear like magic within seconds.

We have used this product previously, prior to the pandemic and then it was no longer available for 2 years. GLAD to see it return, from the good folks at WD40. Excellent aggressive chemistry (chlorine) that does the job, quickly. One of these spray bottles does the cleanup on the upholstery on a 24ft long 15 seat pontoon boat - easily. Spray a SECTION - wait 12 minutes - and wash off with a good blast of water (or power washer on low setting). Caution: Keep this out of your eyes, and away from contact with your hands - AND be SURE you thoroughly RINSE the product off after it has done its thing - 15 minutes. FAILURE TO RINSE THIS OFF OF THE THREADS USED IN YOUR upholstery - will result in the thread just degrading and dissolving and you will end up with no upholstery! RINSE RINSE RINSE --- buyer beware.

This was always my go-to cleaner for mold and mildew spots in the shower. Then it disappeared from the market and I had to try other products, But none of them worked as well as X-14. I was so happy to see it is available again. In my opinion, it is the best of its kind.

I have used this product for years and never been disappointed. It is easy to use, works quickly and prohibits future growth. My husband thinks it's magic.
