In most cases, the finish is safe if you follow the manufacturer’s instructions for use and make sure the drain cleaner isn’t left on the finish for longer than 30 minutes.

Many stores can order Delta® faucets that are not stocked or displayed in the store. Ask the plumbing department manager or store manager for assistance with Delta special order.

You also can preview a large assortment of Delta models in many finishes in the Online Catalog.

The finishes available vary from product to product, so not all products are available in all finishes. The Product Catalog section of our website will allow you to select a product, see what finishes are available for that product, and actually view the product in each of those finishes. Other than chrome, each finish has a two-letter suffix in the faucet model number. A summary of finishes and their two-letter suffix is below:

Brilliance® finishes, designed to not corrode, tarnish or discolor for a “like-new” look for life, are developed by embedding molecules deep into the faucet’s surface, creating a bond that is virtually indestructible. This process is known as Physical Vapor Deposition (PVD). Delta was the first manufacturer to offer this patented process that creates a bond that's virtually indestructible with an incredibly reflective shine. Brilliance resists abrasions and discoloration better than traditional special finishes and, in many cases, better than chrome.

In independent tests using the harshest drain cleaners, the Delta Brilliance drain retained its appearance, while its competitors did not come close. Tested with over 100 household cleaners, the abrasion resistance of the Brilliance finish can even withstand repeated scouring with steel wool. A Brilliance finish is guaranteed not to corrode, tarnish or discolor for as long as you own your home. It can even withstand prolonged exposure to harsh coastal environments.

Delta's Brilliance® finishes are more durable than traditional clear coating. These beautiful finishes, which give your home an instant decorator look, won't corrode, tarnish or discolor. They are designed to look like new for life. The finish was tested against more than 100 common household cleaners. Brilliance will even withstand prolonged exposure to hard water or sea air.

Pin holes in a Delta faucet spout are usually caused by "dezincification," which is the removal of zinc from the brass due to salt solutions, brackish water, mildly acidic solutions and poorly grounded plumbing systems. When the zinc is removed, the copper is redeposited to these areas and the surface of the part. The redeposited copper is a weak mass that is porous and fragile.

If this has happened, you will need to replace the spout. To determine the spout part number for your faucet model, contact your Delta plumber or showroom, or e-mail us.

Traditional Polished Brass finishes were coated with a clear coating to inhibit tarnish. Over time, this clear coat can be broken or scratched with regular wear and tear, abuse or chemical attack, causing the finish to tarnish or the coating to peel. Unfortunately, it's not possible to repair the clear coat so you will need to replace any parts of your faucet that are tarnished or badly scratched.

Normally, finish deterioration is due to years of wear and tear, abuse or chemical attack. There is no repair once the finish is damaged, however you can replace many of common faucet parts where the finish deterioration is most noticeable.
