Granite countertops are a staple in both classic and modern homes, loved for their natural patterns, timeless beauty, and incredible durability. But when dealing with old, faux, unfinished, or unsealed granite countertops, the cleaning process requires a more delicate, informed approach.
These surfaces don’t have the same protective sealers found on newer polished granite countertops, making them more susceptible to staining, dullness, and damage from improper products. In this guide, you’ll learn exactly how to clean and care for these more vulnerable types of granite surfaces—whether you’re maintaining an older installation or trying to protect granite slabs for countertops that have never been sealed.
Understanding the Different Types of Granite Countertops
Old Granite Countertops
Older granite may have lost its seal or never been sealed at all. Over the years, food spills, hard water, and general wear can degrade the surface. This is especially common in homes with granite kitchen countertops or granite bathroom countertops that see daily use.
Faux Granite Countertops
Faux granite is typically a laminate or painted surface designed to mimic natural stone. These countertops are more affordable and non-porous but prone to scratching and wear.
Unfinished or Unsealed Granite Countertops
Granite without a sealer is extremely porous. Water, oil, and acidic substances can easily soak in, leaving behind stains and discoloration. Whether it’s black granite countertops, white granite countertops, or brown granite countertops, unsealed stone needs extra attention and care.
Why Unsealed Granite Needs Special Care
Sealed granite repels moisture and stains, while unsealed stone absorbs liquids quickly, often leading to:
- Dark patches or water rings
- Dull, gritty texture
- Bacterial buildup in porous areas
- Loss of color vibrancy in surfaces like blue pearl granite countertops
Because of this, cleaning agents and techniques used for standard sealed granite can cause damage to unfinished or faux granite countertops. It’s crucial to use safe, effective methods that won’t degrade the surface or leave behind chemical residues.
Safe Cleaning Supplies for Delicate Granite Countertops
To properly clean old, faux, or unsealed granite countertops, you’ll need:
- Mild, pH-balanced dish soap
- Warm distilled water
- Isopropyl alcohol (70%)
- Baking soda
- Microfiber cloths
- Plastic wrap (for poultices)
- Plastic scraper (non-metal)
- Soft sponge (non-abrasive)
Pro Tip: Never use bleach, vinegar, lemon, or ammonia on granite—especially unsealed granite—as these can cause etching or dulling of the surface.
Step-by-Step: How to Clean Old, Faux, and Unsealed Granite Countertops
1. Basic Surface Cleaning
Mix a few drops of mild, pH-neutral dish soap into warm distilled water. Use a soft microfiber cloth or non-abrasive sponge to gently clean the surface. This step is safe for all types of granite, including faux and unsealed.

2. Spot-Cleaning with Isopropyl Alcohol
For stubborn spots, use a 50/50 mix of isopropyl alcohol and distilled water. Spray the solution on the affected area, let it sit for 3–5 minutes, then wipe clean with a dry cloth.
This is especially useful for older installations or affordable granite countertops for modern kitchens that haven’t been recently resealed.
3. Use Baking Soda for Stains
For deeper stains or oil spots, use a baking soda poultice:
- Mix baking soda with water (or hydrogen peroxide for light granite) into a paste
- Apply to the stain
- Cover with plastic wrap and tape edges down
- Leave for 24 hours
- Wipe clean and dry
This works well for custom granite countertops that may have unique colors or textures.
4. Dry Immediately After Cleaning
Always dry your countertops after cleaning to prevent moisture absorption. This is especially important on honed granite countertops, which can be more prone to staining due to their matte finish.
Faux Granite Care Tips
- Avoid abrasive cleaners that can strip the design
- Stick to mild soap and warm water
- Use coasters and trivets to avoid heat or moisture damage
- Don’t use metal scouring pads or brushes
Should You Seal Your Granite Countertops?
If your countertop absorbs water rather than letting it bead up, it’s likely unsealed. Applying a sealant will:
- Prevent future staining
- Enhance color vibrancy
- Extend lifespan of your granite
