What is a good cleaner to remove soap scum from fiberglass tub and walls, I have tried about everything?

You may need a CLR product or lime away.

Usually any foaming bathroom spray works or you can try Clorox clean up.

You should get in the habit of spraying daily.

Good luck.

Clean your fiberglass shower and tub by heating vinegar until hot (but not too hot to work with) and pouring it into a spray bottle. Spray the surface liberally, wait 10 to 15 minutes and scrub with a scrubbing sponge dipped in more hot vinegar and a little borax. Rinse well and dry. Heating the vinegar gives it more kick. You can also use undiluted liquid Fabric softner on a wet sponge and rub it over the soap scum, this will remove the soap scum easily then just rinse with hot water and while rinsing scrub with a nylon type sponge to remove all traces of soap. You can also use WD-40 all you do is spray on the soap scum leave for a few minutes then clean with soap and water and rinse with hot. Good Luck !

A weak solution of sulfuric acid works well with soap, test it on a small patch of the fiberglass first but it shouldn't hurt it. And water is all you need to nutralize the acid after you use it.

Magic Eraser by potential of Mr. clean. i grew to become into skeptical once I first began utilising the product and now I won't stay devoid of it. It takes genuinely no scrubbing. those days, i grew to become into employed to wash somebody's abode (as college scholar makes funds any way attainable). This guy or woman's bathtub had no longer been wiped clean for actually 6 years. It grew to become into disgusting. I gagged oftentimes. in spite of if it took genuinely no scrubbing to get rid of ninety seven% of the stains. I merely went over the section. Rinsed oftentimes. I now use the product for each little thing -- timber paintings, scrubbing corners (the place my mops do no longer attain), and any textured floor. this is wonderful on textured and gentle surfaces. I now purchase one for the finished family individuals.

Try Mr Clean Sponges-No chemicals just get them wet -I use them on my tub to remove soap scum and just to clean it-They are great! And very cheap!

kaboom and a mr. clean magic pad works great and won't scratch the fiberglass

I use Fantistic and a non-scratch scrubbing pad.

I would say Lime Awy, it works great.

kaboom, limeaway, toilet cleaning spray.
