Every gel by volume

Price per fluid ounce from our last update.

All our gels do the same job. You put them on a stain, they sit there for hours while it lifts, and then you wipe them away with a damp cloth. What you are choosing between is the size of the bottle, the tip, and whether a brush is in the pack.

Each product page gives the waiting time exactly as that bottle's own directions state it: anywhere from 3 to 8 hours. Longer is better on old, deep marks.

None of them fixes the damp that caused the marks. Dry the seal after washing and run a bathroom fan, or the lines return.

Questions we get

What exactly does the gel remove?

The dark stains that damp leaves in silicone, grout and caulk. It is a stain remover, not a disinfectant. The lasting fix is keeping the area dry.

How long do I leave the gel on?

Follow the time on your bottle. Our directions range from 3 to 8 hours, and old, deep marks do better with the longer end and a second round.

Can I use it inside the washer drum?

It is made for the rubber door seal and other hard surfaces around the home. After treating a washer seal, run a rinse or cleaning cycle before the next load of clothes.

Will the marks come back?

If the seal or caulk keeps staying wet, yes. Leave the washer door open after a wash, wipe the seal dry, and run the bathroom fan.
