Overview

How to Use This Guide

This guide is organized around two core questions our customers ask most: "What can I use to clean my finish?" and "How do I maintain the valve inside my faucet?" Choose the section that matches your question below, and always follow the instructions specific to your finish or product type.

Cleaning instructions are based on each finish's specific coating process: Brushed Nickel, Polished Chrome, and Stainless Steel — Electroplating; Brushed Gold — PVD; Matte Black — Electrophoresis. Do not apply instructions from one finish to another.
⚠ Failure to follow these care and cleaning instructions may void your warranty.

Brushed Nickel finish

Brushed Nickel (BN)

Electroplated + Brushed

Description of Finish

Brushed Nickel is produced through an electroplating process that deposits nickel and chrome layers onto the base material. A brushing treatment is then applied to create a subtly textured, linear surface that diffuses light and minimizes the appearance of fingerprints and water spots.

Warranty

Limited Warranty for as long as you own your home.

Cleaning Instructions

  1. Use a soft, damp cloth with mild liquid dish soap; use for a limited time only, then rinse thoroughly with clean water.
  2. Dry immediately with a soft cloth — do not allow water to air-dry on the surface.
  3. Periodically apply a quality non-abrasive wax (such as car wax or furniture wax) to protect the finish. Note: waxing may cause a slight color change but will not damage the finish. Test on a less visible area first.
  4. To remove dried water spots: apply a 50/50 solution of household white vinegar and water (limited time only), then rinse thoroughly and dry immediately. If spots remain, contact our support team for guidance before attempting further cleaning.

Do Not Use

  • Strong cleaners such as lime/calcium/rust (scale) removers
  • Green fiber sponges or abrasive pads — contain mineral particles that scratch the finish
  • Steel wool of any grade
  • Bleach, ammonia-based cleaners, alcohol
  • Wet wipes, disinfectant wipes, or any pre-moistened cleaning cloth — many contain alcohol, bleach, or other solvents that can damage the finish
  • Any cleaner not specifically confirmed safe for electroplated surfaces — when in doubt, use only mild dish soap and water as described above
⚠ Failure to follow these care and cleaning instructions may void your warranty.
Brushed Gold finish

Brushed Gold (BG)

PVD + Brushed

Description of Finish

Brushed Gold is produced through a PVD (Physical Vapor Deposition) process, which molecularly bonds a durable gold-toned coating onto the base material. A brushing treatment is applied to create a linear texture, resulting in a warm, lustrous surface with superior resistance to tarnishing and corrosion.

Matte Black finish

Matte Black (BL)

Electrophoresis
Matte Black is sensitive to surface damage. Any visible marks resulting from use of prohibited products or methods are not covered under warranty.

Description of Finish

Matte Black is produced through an electrophoresis process, in which the coating is deposited onto the base material using an electric current in a liquid bath, forming a uniform, flat layer that bonds firmly to the surface. The result is a zero-reflectivity matte finish with strong resistance to chipping and fading under daily use conditions.

By Valve

Valve Body Cleaning & Flushing

When installing a new cartridge, we recommend cleaning and flushing the valve body first. This removes mineral deposits and loose debris that may have accumulated inside the valve, which can damage a new cartridge or restrict water flow.

Water may exit the valve body with significant force. Follow the steps below carefully to control the flushing process.
If you are unsure about any step in this process, contact our support team before proceeding. We are happy to guide you through the process or arrange professional assistance.

Deckmount Faucets — Bathroom Faucet / Kitchen Faucet

The following steps assume the handle, related handle parts, and the cartridge have already been removed. Refer to your product's installation guide if needed.

Recommended Tools

Soft nylon-bristle brush (e.g., soft toothbrush or bottle brush)
Paper towels
Clean, soft towel free of bleach or chemical treatments (to wrap around faucet base)
Large bowl
A second person (may be required for Step 3)

Cleaning Steps

  1. Wrap a towel around the base of the faucet to protect the surrounding surface. Place a large bowl nearby and ready.
  2. Use a nylon-bristle brush to gently scrub the inside walls of the valve body to remove mineral deposits and debris.
  3. ⚠ Two people may be required for this step. Person A holds a large bowl firmly and closely over the open valve body to fully capture the water flow, redirecting it back into the sink. Person B opens the water supply valve only slightly — turn just enough to hear water begin to flow, then stop adjusting. If water sprays beyond the bowl, close the valve immediately and contact our support team before continuing. If separate hot and cold shut-off valves are used, repeat this process for each side independently.
    Unsure about this step? Contact our support team before proceeding.
  4. Use a rolled-up paper towel to absorb residual water from the BOTTOM of the valve body. If this water is not removed, the new cartridge will not seat properly.
  5. Proceed with cartridge installation. Refer to your product-specific guide for detailed cartridge installation instructions.

Wallmount Faucets — Shower Valve & Trim / Tub Filler

The following steps assume the handle, related handle parts, and the cartridge have already been removed. Refer to your product's installation guide if needed.

Recommended Tools

Soft nylon-bristle brush (e.g., soft toothbrush or bottle brush)
Paper towels

Cleaning Steps

  1. N/A — no preparation step required for wallmount installations.
  2. Use a nylon-bristle brush to gently scrub the inside walls of the valve body to remove mineral deposits and debris.
  3. ⚠ SAFETY: Stand fully outside of the bathtub or shower enclosure, with the door or curtain closed if possible, before opening the water supply. Open the water supply valve only slightly — turn just enough to hear water begin to flow, then stop adjusting. If water sprays beyond the enclosure or you are unable to control the flow, close the valve immediately and contact our support team before continuing. If separate hot and cold shut-off valves are used, repeat this process for each side independently.
    Unsure about this step? Contact our support team before proceeding.
  4. Use a rolled-up paper towel to absorb residual water from the BACK of the valve body. If this water is not removed, the new cartridge will not seat properly.
  5. Proceed with cartridge installation. Refer to your product-specific guide for detailed cartridge installation instructions.

Deckmount vs. Wallmount — Quick Comparison

Step Deckmount Wallmount
1. Prepare Area Wrap towel around faucet base; prepare a large bowl. N/A
2. Clean Valve Body Scrub inside walls with nylon-bristle brush to remove mineral deposits. Scrub inside walls with nylon-bristle brush to remove mineral deposits.
3. Flush 2 people may be required. Hold bowl over valve; open water supply only slightly. Repeat for hot & cold sides separately. ⚠ Stand outside tub/shower. Open water supply only slightly. Repeat for hot & cold sides separately.
4. Remove Residual Water Use rolled paper towel to absorb water from the BOTTOM of the valve body. Use rolled paper towel to absorb water from the BACK of the valve body.
5. Install Cartridge Proceed with cartridge installation. Proceed with cartridge installation.
Step 3 (Flush) carries the highest operational risk — water may spray with force. Step 4 (Remove Residual Water) is critical for proper cartridge installation — any residual water or debris left behind can prevent the new cartridge from seating correctly.
