How to Take Care without Sealing Quartz Countertops 

Issues can occur when you fail to take proper care of your Quartz countertop. That is why it is essential to follow certain guidelines:

1. Avoid Cleaning Using Products that Can Lead to Abrasion 

Do not clean your countertop using abrasion-causing products because they will ruin its shine. In the end, you will get a dull worktop. For example, avoid alkaline cleaners that have a pH higher than 10.

 2. Use Heat Protectants 

Exposure to extreme heat may destroy the countertop surface because it may not be heat-resistant. However, this does not mean your quartz countertop is heat-proof.  

For example, when you put a hot pan or pot on your countertop surface for longer, it might result in marks or discolouration. Therefore, always make sure you add a trivet or potholder before placing a deep fryer, electric pressure cooker or hot pan.

3. Be Careful with the Chemical Exposure

Avoid the exposure of your counter to chemical-based products such as paint thinners, household cleaning products, etc.

4. Do Not Cut Things on the Countertop

Avoid cutting citrus and other acidic foods off the surface of your kitchen countertop. The acids they release may ruin your quartz top and make it appear dull. Rather, use a cutting board for chopping those veggies.

5. Avoid Using Bleach

To avoid losing the shine of your quartz countertop, do not use bleach and solvents (such as acetone).

 6. Do Not Repolish

Avoid repolishing the countertop surface using polishing pads or sanding pads.

7. Avoid Using Quartz Stone for Outdoor Kitchen
