STEP 1

Remove Mold & Mildew Stains with Xanigo Marine's Mold & Mildew Stain Remover

Our mold & mildew stain remover is a very effective way to remove mold and mildew stains. Being a harsh chemical it should only be used once to remove the mold stains, then the preventer should be applied to prevent the mold from coming back. Liberally apply the Mold & Mildew Stain Remover to your seats. Let it sit for 60-90 seconds but do not let dry. Additional solution may need to be applied— keep it wet. Agitate in a circular motion with a brush to releease the mold stains from the pores. Rinse thoroughly with clean water.

STEP 2

Neutralize The Stain Remover

After rinsing the remover off with fresh water, it's important to make sure any leftover stain remover is neutralized to reduce the risk of impacting your seats and stitching. Spray the Waterless Wash onto your seats and wipe it in with a microfiber cloth to neutralize the chemicals in the stain remover.

STEP 3

Remove Mold & Mildew Stains with Xanigo Marine's Mold & Mildew Stain Remover

With just one application, your boat will be protected against stain-causing mold and mildew for up to 90 days. The preventer creates a covalent bond to the surface that it is applied to. You can apply this to almost any marine surface including: vinyl seats, life jackets, canvas, ropes, compartments, live-well, bilge, patio furniture and other areas of high moisture. Spray the Mold & Mildew Preventer onto a clean, dry surface and spread evenly with a microfiber cloth or use a professional Xanigo Marine applicator and spray and walk away. No wiping necessary. Remember to spread, not wipe off.

STEP 4

Maintain Your Seats with Xanigo Marine's Waterless Wash

Keep your boat clean between mold prevention applications without the use of harsh chemicals or wasting water. Spray the Waterless Wash onto your seats, let it sit for a few seconds and wipe off with a microfiber cloth. Remove sunscreen (a major food source for mold) and leave a refreshing smell without impacting the protective layer created by the mold & mildew preventer. Also, a great way to shine up a gel-coat quickly!

"Amazing product and great people. Here in the south Mississippi humidity, mold and mildew thrives on upholstery and compartments. I use Xanigo preventer on all of my full details. My DIY clients also love the spray bottle application to use between details and even around the house."

Justin

Verified Purchaser

I have an older boat that had mildew stains that had been there years. Literally bought half a dozen products last year to try and remove them to no success. Sprayed the mildew remover on and could watch the stains disappear before my eyes.

Rick Pincus

We have done two applications in the last 9 months on our 2019 Twin Vee and the upholstery looks like new with mildew being non-existent. We bought the corded unit since we have electric at our lift. It takes less than 10 minutes to apply and couldn't be easier! I love this product and highly recommend it. If I could give more than five stars, I would!
