A refinished bathtub can last 10+ years — or it can start looking dull and scratched within a year. In most cases the difference comes down to what cleaner you use. This is the single most important maintenance topic for a refinished or reglazed surface.
What Destroys a Refinished Finish
Abrasive cleaners — Comet, Ajax, Bon Ami, and similar powder cleansers contain grit that physically scratches the coating with every use. Each cleaning session removes a microscopic layer. Over months, the finish clouds and dulls.
Bleach-based cleaners — Concentrated bleach (like straight Clorox sprayed directly on the surface) can spot-etch and discolor epoxy and urethane coatings. Diluted bleach is less of a concern, but habitual use degrades the finish over time.
Magic Erasers / melamine foam pads — These feel soft but are micro-abrasive — they work by sanding the surface at a tiny scale. On a refinished tub, they remove the surface gloss. Don’t use them, ever.
Scrubbing pads (green Scotch-Brite) — Same problem. Any abrasive pad scratches the coating.
Harsh chemical degreasers — Some bathroom “deep cleaners” use solvents that can soften or cloud an epoxy coating. If a cleaner smells strongly of acetone, MEK, or other ketone solvents, avoid it.
What Is Safe
The rule is simple: non-abrasive, non-bleach, pH-neutral or mildly alkaline liquid cleaners.
Approved categories:
- Dish soap (Dawn, Palmolive, etc.) — diluted with water
- Spray cleaners specifically formulated for fiberglass or refinished surfaces
- Vinegar solutions for mineral deposits — but rinse quickly (prolonged acid contact isn’t great)
- Soft cloth or sponge — no pads with any abrasive texture
Best Specific Products
Best Overall: Rejuvenate Scrub Free Soap Scum Remover
Rejuvenate Soap Scum Remover is specifically formulated for delicate surfaces including acrylic, fiberglass, and refinished tubs. No abrasives, no bleach, and it actually cuts soap scum effectively. This is what I’d recommend buying specifically for a reglazed tub.
Best Budget: Method Daily Shower Spray
Method Daily Shower Spray — spray after showering, no scrubbing needed. Plant-based, no harsh chemicals. Won’t hurt a refinished surface and the daily use keeps soap scum from building up in the first place.
Light Mineral Deposits: White Vinegar, Used Briefly
For light hard water deposits and ring stains, undiluted white vinegar on a soft cloth, left no more than 5 minutes, then wiped and rinsed completely. Vinegar is a weak acid, and used briefly like this it is the one acidic option a refinished surface tolerates. Do not let it dry on the coating.
Acid Descalers: Not on a Refinished Tub
This needs saying plainly, because these products are excellent on other tubs and get recommended constantly.
Lime-Away, CLR, and every other acid descaler belong on porcelain, acrylic and fiberglass — not on a refinished surface.
They work by dissolving mineral deposits, and an epoxy or urethane coating a few thousandths of an inch thick is not chemically inert to them. Repeated contact dulls the gloss, and prolonged contact can etch or lift the coating outright. Once that happens there is nothing to polish back — the film is gone.
Lime-Away genuinely is the best bathtub cleaner for most tubs, and it is covered as such in what is the best bathtub cleaner. If you have heavy mineral buildup on a refinished tub, the honest answer is a gentle product, more dwell time and more patience — not a stronger chemical.
What to Avoid — Specific Products
| Product | Problem |
|---|---|
| Comet | Abrasive powder |
| Ajax | Abrasive powder |
| Scrubbing Bubbles (original) | Contains bleach compounds |
| Lysol Power Bathroom Cleaner | Can be too harsh for coatings |
| Bar Keepers Friend (powder) | Abrasive |
| Green Scotch-Brite pads | Abrasive |
| Magic Eraser | Micro-abrasive |
Note: Bar Keepers Friend makes a liquid version that is less abrasive — but I’d still avoid it on a refinished surface.
How to Clean Without Scratching
- Use a soft sponge or microfiber cloth — nothing with any texture
- Apply cleaner, let it sit for a minute to do the chemical work
- Wipe, don’t scrub
- Rinse thoroughly
Elbow grease damages refinished surfaces. Give the cleaner time to work and wipe gently.
The Long Game
If you use the right cleaner and a soft cloth every time, a refinished tub can hold its gloss for 7–10+ years. If you use Comet and a scrubbing pad, you’ll be looking at re-refinishing in 2–3 years.
It’s one of the easiest maintenance wins there is — just buy the right cleaner and don’t use anything scratchy.

Common Questions
What is the best cleaner for a refinished bathtub?
A non-abrasive liquid spray with a soft cloth. Rejuvenate Soap Scum Remover is formulated for exactly this kind of delicate surface — no abrasives, no bleach — and Method Daily Shower Spray works well for daily prevention.
Can I use Lime-Away or CLR on a refinished tub?
No. Acid descalers are excellent on porcelain, acrylic and fiberglass, and they do not belong on a refinishing coating. They dull the gloss with repeated contact and can etch or lift the coating outright, and there is nothing underneath to polish back to.
Why can't I use Comet or Bar Keepers Friend powder?
Both contain abrasive particles that are harder than the coating. Each cleaning removes a microscopic layer, the finish clouds, and a rougher surface then holds soap scum better — so you clean more often and accelerate the damage.
Are Magic Erasers safe on a refinished tub?
No. Melamine foam feels soft but works by abrading — it is effectively very fine sandpaper. On a refinished surface it removes gloss permanently.
How long will a refinished tub last if I clean it properly?
Seven to ten years or more of good gloss with the right cleaner and a soft cloth. With abrasive cleaners and a scrubbing pad you can be looking at re-refinishing in two to three.
