How to get the shower REALLY clean?

I had a similar problem,I found that "Kaboom"really works.It smells like it has muriatic acid,but the stuff works.

Hi ~ Ok, first off, since your shower is cultured marble, that means it is manmade. On 'cultured marble' you have to be extremely careful. The shiny surface that you see is called 'Gelcoat' and even if it were manufactured well, that coating will only be about as thick as a person's fingernail. If you remove too much and 'burn through' the gel, it will need professional attention. You do NOT want to use some of the abrasives that are recommended below. Nor do you want to use products intended for natural marble.

If you are located in an area like Florida where the water is hard and mineral rich, you are in for quite a project. But the good news is that it CAN be made to look as good as new. First I would remove all of the caulk, being very careful not to scratch the surrounding area. If you use a blade, just be certain to not let it slip. I would first clean the surface with a solvent. I believe Home Depot sells Toulene, and if so, use this. You can use Acetone but be sure not to let it sit on the surface. Pour it on a soft cloth and then wipe the surface with it. In areas where the build up is thick you may be forced to sacrifice some of the shine by using a very fine 3M pad to lightly remove the build up. Please make sure you have great ventilation, or take frequent breaks. If you are not used to using solvents they will make you dizzy very fast.

After you use the solvent for the primary cleaning, you can use a product from Home Depot called 'Gel-Gloss'. It is a cleaner but also contains a caranuba wax that can be used repeatedly without a thick build-up. The way I use it for cleaning cultured marble is to use the soft 3M pad on a dual action sander. It works sort of as a light rubbing compound. Just do the final application by hand (soft cloth).

Cultured marble can be polished using a 7 1/2 inch pad on a buffer, using most any of the compounds for the auto body industry. After the final clean, you will need to recaulk the shower making sure to get plenty of caulk deep into the seams. Use water (wet t- shirt cloth over finger) to clean up any messy caulk joints.

I know this sounds like a project..... and it is. You are talking at least a full day's work. Good luck.

If the tile has grout between it and it has mold, kitchen and bath clean up made by clorax. Leave for a while and it will get most of that mokd if not all. I suggest the Mr. Clean magic eraser. If really bad, try a good degreaser and a scrubber, use will be able to tell the pressure to use. Use same method on the door. I own a cleaning company and we get lots of these. Especially when their evictions.

There are some great mildew, and rust removers on the market. Why don't you try a Lowe's store if you have one in your area. Whatever you do please do not use a product called 'KABOOM'. I have never been alergic to anything in my life weather it be food or medicine. I used kaboom to clean my bathtub, and an hour later I was in the emergency room at the hospital My whole body looked like I was an alligator, I couldn't breath, and had to be taken to the trauma unit where I was hooked up to a heart monitor. I still don't know what was in that stuff but I will never use it again. Make sure whatever household product you use won't affect you like I was affected.

CLR (or something like it) and maybe some bleach based liquid cleaning product to help remove the stains.

no doubt you've tried these already ...

they also make a marble cleaner ... sur la table produces one and so does a company named listro. there are others, and they generally run around 20 bucks.

Bicarbonate of soda...make into a paste with a little water...rub it around onto the surface with a cloth..and scrub off with a brush after 10 minutes. For extra sparkle...use white vinegar afterwards.

Lysol Bathroom & Mildew Cleaner works great.. but make sure you have a lot of air flow around..that stuff is nasty to your lungs! Spray it around and let it soak for an hour before scrubbing & then rinse well.

BLEACH >>> Block the drain... And pour in pure bleach.. let it set for the day .. most of the crap will be gone .. Scrub a bit , and you may have to repeat , if its REAL nasty .. ( Careful with the bleach ..don't get it on your clothes it will ruin them )

Toothpaste;)

call a tile store that sells marble and ask them. it may be hopeless if the sufrace of the tile was allowed to get porous.
