Bathtubs can develop scrapes and marks with time. These scrapes fill with dirt and debris and produce the bathtub seem dirty. It is possible to polish scratches to remove the dirt and restore the look of the bathtub, but you must use the right cleansers and work carefully so you do not produce new scratches. Physical exertion could be saved by employing any polishing creams or fluids into the gloss pad on a rotary instrument and letting the tool do the hard work for you.
Baking soda is a antibacterial cleansing powder that is all nontoxic and natural. Baking soda is somewhat abrasive and it may be used to polish small scratches in fiberglass or porcelain bathtubs. To use it, combine sufficient water with baking soda to produce a thick paste. Rub the paste into the bathtub to eliminate the scratches. Rinse the bathtub with clean water when you are finished. This generally works only on superficial scratches.
Lemon Juice & Borax
Borax is just another all-natural cleansing powder, but it is poisonous if ingested. Make a paste using the borax to grind small scratches on a ceramic or ceramic bathtub. To do so add only enough lemon juice to borax to create a thick paste. Rub the paste to the scratches till they are gone. The acid from the lemon juice helps eliminate alkaline soap scum residue from the scrapes. This functions only on superficial scratches.
You could also use commercial ceramic or ceramic polishers, which contain mild abrasives to remove hairline cracks and scrapes without damaging the bathtub. Choose a commercial product and test it on a small area of the bathtub to ensure it does not alter the color or feel of the bathtub. These generally just work on superficial scratches.
Sanding the bathtub using a fine-grit sanding accessory on a rotary instrument helps eliminate deeper nicks and scrapes. You can also use a fine-grit sandpaper. Work till the nicks and scrapes are gone and finish the job using a buffing wheel to restore the glow.
To finish polishing a bathtub, you may apply auto wax to make it glow and protect it from further stains and scratches. To use it, then apply a thin layer of wax to the bathtub using a sterile cloth. Work until the whole bathtub is coated in the wax. Buff excess wax off using a sterile cloth in circular motions, or use a buffing accessory on a rotary tool.
