Our Stone Cleaning Crew Made This Shower in Queens Look As Good As New

November 26, 2025

A homeowner in Queens was wary about using new cleaners after seeing the results of his previous attempts. He'd noticed the discoloration of his shower surfaces months before and tried different ways to bring the stone back to life. The results were disappointing at best and downright concerning at worst, making the owner question the safety of using generic cleaners in this part of the house. That's why he didn't hesitate to ask for more information when he overheard his next-door neighbor talk about our stone cleaning service in Queens.


His neighbor praised the quality of our results, and it wasn't hard for the owner to find our website from there. He went straight to our picture gallery to check out our work on different natural stone surfaces, and once he was pleased with his findings, he decided to give us a call.

At his convenience, we were at his doorstep later that week for an in-home evaluation. During the evaluation, our crew observed the marks on the floor and all the moldy spots between the tiles. Through his constant cleaning efforts, the owner could preserve parts of the grout, but dirt still spread around the porous surface, resulting in black and brown spots in different areas of the large shower stall. The stone also looked duller and darker due to the residue that got stuck on the porous surface.

Our techs explained that multiple factors had come together to worsen the issue. For one, the minerals carried by hard water corrode hard surfaces until they crack, on top of causing discoloration on cement-based grout. Meanwhile, store-bought cleaners create a soapy film that pushes the dirt into the grout pores, creating new stains every day. Luckily, we have the expertise to address all these issues, so our experts immediately offered to work on the shower with Sir Grout's professional equipment. The client thanked us for sharing our insights and immediately scheduled a second appointment.

Following his request, our specialists returned to his house after a couple of days for the restoration. First, we needed to prepare their working space, so we covered the area around the shower with clear plastic and masking tape. With the help of a permeating cleaner, our specialists removed all the embedded dirt, including all the soap scum around the sink and the dirt that was stuck on the wall grout. We also used a 275-degree vapor cleaner for good measure, removing all the mold and mildew from the stone.

It was time to restore the damaged grout. We carefully detached the loose caulk and installed epoxy grout on every corner. Resistant to water and mold, this solution withstands weeks of activity without showing signs of decay. Cement-based grout has a porous surface that absorbs all sorts of external elements with ease, but our epoxy solution is made to rule out these issues.
We also revamped the walls with our flagship ColorSeal, an acrylic-based sealant that's designed to repel common shower elements. With this protection in place, the grout remains spotless and withstands constant exposure to moisture, soap, mineral residue, and more.

Our crew called the client back into the bathroom after checking that everything was in order. He was in awe when he saw the stall, marveling at the stone's elegant appearance and the grout's new color. He was particularly impressed with our work on the floor and thanked us for restoring the stone to its former beauty.

Satisfied with another successful restoration, we started putting away our equipment, and we took the opportunity to share some additional cleaning pointers. Our experts started by recommending pH-neutral cleaners over traditional products for the maintenance of natural stone surfaces. Sir Grout's Natural Hard Surface Cleaner stands out from most of the products in the market for removing stubborn stains in record time, all without altering the stone's appearance. It works against the embedded dirt between the tiles and does a quick job of eliminating the efflorescence inside your shower area. Moreover, our product doesn't release toxic fumes into the air, so you can work more comfortably, keeping a safer environment for people and pets.

We also recommend using non-abrasive tools to scrub off the dirt since stone surfaces can get easily scratched when you use a steel wool or other sharp objects. Regular cleaning sessions with pH-neutral products are often enough to keep most of the dirt at bay, as long as you use a towel or a squeegee to remove the dirt.

Good indoor ventilation also does a lot to simplify your cleaning routine. The constant circulation of fresh air slows down the spread of mold and keeps moisture from being absorbed into porous surfaces. Showers are damp for most of the day, so the air gets stale much faster. For this reason, we remind clients to open the windows and doors from time to time. The owner thanked us for sharing these pointers and promised to recommend our services to everyone he knew.
