Hi Javier, This tell how to do it, Hope it helps... https://www.hunker.com/13421638/how-to-whiten-plastic-or-fiberglass-tubs-showers
This is what I use to clean my entire bathroom. You cannot use this on granite or marble, but it can be used everywhere else.
Heat up 1 cup of white vinegar, mix in about 1/4 cup of Dawn Premium. Not the dollar store kind, because it is too thin. When mixed, pour into a spray bottle and fill with water. Shake. Spray down the grout and let it sit overnight. In the morning rinse. If you have stubborn stains, spray again. Use this mixture a few times a week. It will keep your grout and tiles clean. Also works wonders in the toilet bowl to keep hard water stains at bay. Oh you only have to heat the vinegar one time when you add the Dawn.
What are your stains? If rust, use CLR-calcium, lime, rust. Available at diy stores.
Easy Off No Fume Oven Cleaner in the BLUE can. Works on enamel, porcelain, and fiberglass. Some fiberglass tubs have a textured bottom that is hard to clean.

I have one with a non slip bottom that was horrible to clean. I tried to everything I came across. Then I discovered wet & forget shower. You spray it once a week after you get out of the tub and that's all. It is amazing. A bit pricey but it lasts a very long time and worth every dime.

Hi Javier. Pour some undiluted white vinegar into a clean, empty spray bottle. Use it to spray all of your tubs surfaces , including hardware. Wet a cleaning sponge with more vinegar. Then sprinkle baking soda onto the tub's surfaces, and use the wet sponge to scrub it gently. Rinse the tub well to remove all remaining baking soda. Repeat if necessary. Good luck Javier.
bar keepers friend or bon ami, does a great job. I also like soft scrub.
I have a spray bottle with equal parts ACV and Hydrogen Peroxide. I keep it in the shower so that when I'm done I spray down the walls and floor after I step out. I have always lifted out the bath mat and laid it over the side of the tub on the floor mat to keep it from dripping on the floor. If we wind up with a build up from hubby's therapeutic bathsalts before spraying I'll sprinkle baking soda then spray. Before taking the next shower or bath we spray down the shower with hot water. I no longer have to scrub the tub/shower.
Pour undiluted white vinegar into a clean, empty spray bottle.
Spray all of your tub's surfaces, including cracks, crevices and hardware. Let the vinegar stay on the tub for about 30 minutes.
Wet a cleaning sponge with vinegar.
Sprinkle baking soda onto the tub's surfaces and use the wet sponge to scrub it in gently. The combination of the vinegar's cleaning and disinfecting properties, along with the mild abrasiveness of the baking soda, will clean your tub thoroughly and bring it back to a shine.
Rinse the tub well to remove any remaining baking soda.
