Direct answer
How do you clean a reglazed tub?
Use a non-abrasive liquid cleaner or a little dish soap on a soft sponge, wipe, then rinse — no powders, no scouring pads, no harsh chemicals. Wait the full 24–48 hour cure before first use. Questions about your finish? Call (510) 746-8748, Mon–Fri 8 AM–5:30 PM, Sat 9 AM–4 PM.
What should you avoid?
Abrasive powders, green scouring pads, magic-eraser sponges, bleach, ammonia and strong acids — including most rust and lime removers. They scratch or dull the acrylic-urethane topcoat.
What about Berkeley's hard water?
Wipe the tub dry after each use so East Bay minerals never settle, and treat light scale with a brief, diluted vinegar rinse you wash off fast. Booking a fresh reglaze? Schedule it online and we will hand back full care instructions.
Why a reglazed tub needs different cleaning than porcelain
A reglazed tub looks like porcelain, but it is not. The surface is a sprayed acrylic-urethane coating bonded over the original enamel, and that coating is tougher than people fear and softer than the factory glaze it replaced. The factory porcelain on a cast-iron tub is a glass-hard, fired-on glaze that shrugs off scouring powder; the refinish on top of it is a cured plastic film that does not. Treat a fresh reglaze the way your grandmother scrubbed her cast-iron tub — with a can of abrasive cleanser and a stiff pad — and you put thousands of fine scratches into the topcoat that read as a dull, hazy patch within a year. That is not the finish failing; it is the finish being sanded.
The good news is that a coating built to survive a decade of bathing barely needs any work to stay clean. Soap film and body oil wipe off with a liquid cleaner and a soft sponge, and because the surface is non-porous, dirt sits on top rather than soaking in. The whole care routine comes down to two ideas: clean it gently, and do not let Berkeley's hard water sit on it. Get those two right and an East Bay finish holds its gloss for the full 10–15 years. Diego hands every customer the same short list at the end of a job, and the customers whose tubs still look new at year twelve are the ones who followed it.
Berkeley's hard water and what it does to a finish
Berkeley and most of the East Bay are supplied by EBMUD, whose water is moderately hard — soft compared to inland California, but mineral-rich enough that you see it. Every bath leaves a thin film of dissolved calcium and magnesium behind, and when that water dries on the surface it crystallizes into the chalky white scale familiar to anyone with a glass shower door in the hills. On a reglazed tub that scale is cosmetic, not structural — it sits on top of the coating, it does not eat into it — but the trouble starts with how people remove it.
The instinct is to reach for a lime-and-scale buster or a rust remover, and those are exactly the products that ruin a reglaze. They work by being strongly acidic, and a strong acid left on an acrylic-urethane topcoat etches and dulls it. The fix for hard water is not a harsher chemical; it is preventing the deposit in the first place. A quick wipe-down with a towel or squeegee after a bath clears the mineral-laden water before it can dry and crystallize, and that single habit does more for a Berkeley finish than any product on a shelf. For light scale that has already formed, a very dilute white-vinegar solution, applied briefly and rinsed off within a minute, lifts it without harming the coating — but it is a quick rinse, never a soak.
Products to keep away from a reglazed tub
The fastest way to wreck a good finish is the cleaning aisle. Abrasives and harsh chemicals are the two categories to avoid, and most of the products people reach for by reflex fall into one of them. Here is the short blacklist.
| Avoid | Why it harms the finish | Use instead |
|---|
| Abrasive scouring powders | Micro-scratch and dull the gloss | Non-abrasive liquid cleaner |
| Green scouring / steel-wool pads | Sand the topcoat | Soft sponge or microfiber cloth |
| Melamine "magic eraser" sponges | Act as a fine abrasive — they buff away gloss | Soft cloth + dish soap |
| Bleach & ammonia cleaners | Yellow and degrade the coating over time | pH-neutral / dish-soap mix |
| Lime / rust / scale removers | Strong acids etch and dull the surface | Diluted vinegar rinse, briefly |
| Suction-cup bath mats | Trap water and lift the finish | Breathable mat or sprayed non-slip |
If you are unsure about a product, the simple rule is: if it is gritty, if it foams aggressively on contact, or if the label warns about etching or strong fumes, keep it off the tub. A plain liquid dish soap and a soft cloth handle 95% of real-world cleaning on a Berkeley reglaze.
How cleaning habits decide whether you reach 15 years
Two finishes sprayed the same day in two Elmwood bathrooms can age completely differently, and the difference is almost entirely the cleaning. The tub wiped dry after baths and washed with dish soap stays glossy and watertight past year twelve. The tub scoured weekly with abrasive powder and left to dry hard-water spots goes hazy in the wear zone by year seven. The coating is identical; the routine is not. In Berkeley's moderately hard water, the mineral load makes that gap wider than it would be in a soft-water town, because the temptation to reach for an aggressive scale remover is stronger.
This is also why a worn finish is rarely a dead finish. If a reglazed tub has gone dull or rough, the cause is usually surface scale and micro-scratching, not a coating that has failed — and a gentle dish-soap wipe plus a switch to non-abrasive products often brings the gloss back. When a finish genuinely has worn through after a decade-plus of use, Diego can buff or re-spray it for a fraction of replacement cost rather than tearing out the tub. Either way, the surface is renewable, and good cleaning is what stretches the time between refreshes. See how the finish is applied and why renewing beats replacing.
