About the Home Stain Gel
Dark marks on a washer seal or along the caulk of a tub are rarely on the surface alone. They sit in the silicone. A spray runs off them and a sponge only smears them. A gel stays put long enough to work on them.
Dry the area first, then lay a thick bead of gel over the whole mark and leave it. Our directions for this bottle say 5 to 8 hours. Wipe it away with a damp paper towel or rag and look again: stubborn lines often need a second round.
What it will not do
It does not fix the damp that caused the marks. A seal that stays wet will mark again.
It is not a disinfectant and we do not sell it as one.
It is for hard surfaces and silicone. Fabric, carpet and bare wood are not on the list.
The sizes are the same gel. The 5 fl oz bottle covers a washer seal and a couple of shower corners. The 16 fl oz bottle is for a whole bathroom of caulk, or for a household that repeats the job every few months.
After a washer seal, run a rinse or cleaning cycle before the next load of clothes, so no gel is left where fabric can touch it.
Printed word for word, the lukewarm ones included. Ratings are shared by every size of this product.

The Sugelary Mold Stain Cleaner definitely gets the job done, but it isn’t quite a “spray-and-walk-away” solution. On the positive side, it proved to be very effective at tackling stubborn mold stains—especially on the rubber gasket of a front-load washing machine, where buildup can be particularly tough.

Good for the shower. NOT GOOD for the washing machine. My light laundry had yellow stains even after I had done several loads of laundry already. Including a sanitizing program. Only after 10 loads it was okay again.

This stuff is amazing! The caulking in my shower was admittedly pretty bad. I piled this onto the bad spots and left it overnight for about 12 hours. I was amazed when I cleaned it off! It got rid of 90% of the mold, and didn't eat away the caulk. all you have to do is pour it on, let it sit and rinse!
