how to clean fiber glass bath tub?

[space-time]

I think the bath tub is fiber glass, and there are some stains that are probably from hard water and or soap.

Anyway, I have some "Bar Kepper's Friend" and I am willing to do some scrubbing. Would that work? anything else that is more effective but won't scratch the tub?

Thanks

If it's hard water stains I would think something like CLR would work.

Original formula CLR Calcium, Lime, & Rust Remover uses a powerful, EPA-approved formula to blast through calcium, lime, and rust on a variety of surfaces, without rubbing or scrubbing.

* Patented formula quickly and easily dissolves calcium deposits, lime scale, and surface rust
* Safe and effective on glass, tile, brick, stucco, fiberglass, porcelain, chrome, and stainless steel
* Use on tubs, toilets, sinks, shower heads, and other bathroom and kitchen fixtures
* Great for appliances, including coffee pots, humidifiers, dishwashers, and washing machines
* Non-abrasive formula is septic safe and uses no phosphates, ammonia, or bleach

Safe, fast-acting CLR Calcium, Lime, & Rust Remover quickly zaps calcium deposits, lime scale, and rust, leaving surfaces clean as new.

yeah, I used CLR in the past, but it seems corrosive, isn't it?

I will try to see of some manuals scrubbing does anything (could be really dry soap?), if not, I will try CLR


thanks

Just don't use straight bleach :oldfogey:

Don't scrub with any abrassive. It could damage the finish. Start with CLR.

Don't scrub. Mine got stained with iron and I ruined it scrubbing it with various cleaners. Now, it has dark splotches all over it, plus the iron stains.

Steam clean, or pressure washer.

We add a bit of (20 mule team) borax to the laundry for to help with hard water and I've used it to clean the porcelain tub. Just don't use an abrasive nor scrub too hard. Worst stains we get in the tub are the little green drip stains under the spout from the copper pipes, anyway.
If I clean the whole tub it looks a little shinier , so it might be cleaner because it looks it.

We use Borax, or Baking Soda mixed with lemon juice to clean and shine any porcelain and tiled surface.
