For both finishes you can use normal household cleaners (anything ammonia-based) or just use warm soapy water and a non-abrasive house hold sponge, etc. or a commercially available stone resin (solid surface) cleaner to remove most residues. DO NOT use anything acidic as it could damage the finish. Neither of our finishes should stain easily with normal regular cleaning.

Stone resin is known for it's strong, long lasting heat retention. The Glossy finish is a tad easier to clean due to the sleekness of it. All in all both finishes are very durable and if you do happen to scratch the surface, the beauty of stone resin is that you can sand it right out and it looks good as new. If this happens to the Glossy finish, after you sound the scratch out, you need to reapply the gloss finish which we will supply you with free of charge - very simple.
Daily use:

The nonporous surface of the resin keeps your tub resistant to stains, scratches and discoloration. To keep your resin bathtub in prime condition, wipe the surface with a soft cloth after each use. Most dirt will wash off with clean water. When using a cleaner, choose one that is mild and safe for painted surfaces. Avoid products that contain abrasives, acids or ammonia.

For stubborn residues, a semi-abrasive cleaner like Comet or Ajax should do the trick. With the matte finish, scratches can be easily sanded out with a fine sand paper.

To repair small scratches, smudges, scuffs, etc.:
Use water to remove dirt and dust from the surface.
Use #800 sandpaper (coarser-grit) and rub in small circular motions until the scratch is gone.
Follow with #1200 sandpaper (finer-grit) and rub over the surface of the scratch to smooth.
Dry with a towel.
Polish the surface with a cloth and a polishing compound for automobiles, such as 3M Extra Cut Compound.

First paragraph, use ammonia; third paragraph, avoid ammonia!??

Hello there. Sorry about that typo from our old Care & Maintenance guide. Here is our updated guide:

All Badeloft products are manufactured in Stone Resin, an ultra-smooth, non-porous material
that helps keep grime and calcium deposits in check.

For regular cleaning of both Semi-Gloss and Matte finishes, we recommend using widely
available cleaning products such as: Mr. Clean, Fantastik, etc. The Matte finish may occasionally
require a mildly abrasive product.

Never use petroleum-based products when cleaning, i.e. paint thinners or other solvents,
as they may damage the surface. (Note: Personal hygiene products and cosmetics will NOT
damage the surface.)

Standard Cleaning
