That black line along your tub won't scrub out.

You've sprayed it. You've scrubbed it with an old toothbrush. It comes back looking exactly the same — because the staining is inside the porous silicone, and a thin spray only sits on it for about four seconds before gravity pulls it into the drain.

MoldReset Pro is a thick cling gel built for one job: staying put on a vertical seam long enough to actually work on the stain underneath.

Pipe it on. Leave it overnight. Wipe.
No scrubbing. No toothbrush. No re-caulking.

How to use

1 · Dry Make sure the surface is dry first — gel grips a dry seam far better.
2 · Pipe Run an even bead straight along the caulk line or grout seam with the precision nozzle.
3 · Wait Leave it 4–8 hours. Overnight works best.
4 · Wipe Wipe away with a damp cloth or paper towel and rinse.

Questions, answered

Why a gel instead of a spray?
A spray is designed for flat, horizontal surfaces. On a vertical caulk seam it runs off almost immediately. A thick gel holds its position on the seam for hours, which is the whole point.

Do I need to scrub?
No. Pipe the bead on, leave it, then wipe it away. No brush required.

How long until I see a difference?
Most people leave it on overnight and wipe it off in the morning. Heavier, older staining can need a second application.

Will it work on my coloured grout?
Please don't use it on coloured grout, natural stone or unsealed marble. It's built for white silicone caulk and standard grout. Always test a hidden area first.

Is it safe around the house?
Treat it like any bathroom cleaning chemical: ventilate the room, wear gloves, keep it away from children and pets, and never mix it with other cleaning products.

When will it arrive?
Free US standard shipping, typically 5–12 business days. You'll get tracking by email as soon as it ships.

What if it's not for me?
Unopened bottles can be returned within 30 days. Email us and we'll sort it out.
