Directions for Use

Formula HLF

The four magic ingredients are:

  • Formula HLF

  • Water

  • Agitation

  • Time




Use a solution of 5:1 up to 10:1. For my valves I use the 16 oz short mason jar, and put enough solution to cover the cylinder portion of the valves. The mouth of the mason jar is just right for holding the valves upright. The great thing about the mason jar is, you can put a lid on it, and use the solution a couple more times!


I dip the valves into the diluted solution, then use a toothbrush for a quick brush on the valves to get the process underway, then I let the valves soak for about 15 minutes for well maintained valves, but up to a couple hours for really bad ones. One customer leaves his valves overnight. Brush again firmly, and then rinse generously. Your pistons should be squeaky clean, with no soap or oil residue.


Next, the valve casings: If you have a valve casing brush, dip the brush into the diluted solution, and run it though the casings slowly to soak the interior well. Do this in each casing three or four times, and then let soak for the same time frame as the pistons. Then dip the brush in the solution again, and brush the interiors of the casings thoroughly, and rinse generously.


The rest of the horn should be disassembled, and soaked in a bath with Formula HLF solution. Use a snake to clean interior of the tubing, use a brush to clean the outside of the throw slides and tuning slides, and rinse generously. Remember, Formula HLF destroys germs as well at the molecular level!  The smell and germs will all be gone, and you can reassemble the horn using valve oil and slide grease of your choice. After you reassemble, pour a few drops of valve oil into the leadpipe and blow to recoat the tubing with new oil. This will help moisture to move along to your water keys for dumping, and help with corrosive effects of saliva and small particles from the mouth.


The key is to get to bare metal so that you can start with a fresh horn! With no old oil or soapy residue on the horn, your valves will be super responsive. Nothing else on the market destroys the old oil at the molecular level, or does so so safely!!

The Valve Stripper

Take it OFF, Take it ALL OFF!



Remove the piston, rinse under running water and let dry (optional), spray The Valve Stripper onto each valve liberally. Use the provided brush on the exterior and the ports of the piston or rotor, then immediately wipe with the microfiber cloth. Repeat if needed. The old built up oil residue comes off completely.

The Valve Stripper is:


Odor Fee

PH neutral, Safe for all parts of your horn

Non Flammable

American Made and Packaged.


Use as often as needed, but for best results, check out the PrestoValves line of Hybrid Valve Oils! The REALLY last longer and have NO Odor!

Liquid DiaBrass Spray

Nano Ceramic Protection

Diamond-Like Brilliant Protection

For all Brasswind Finishes


Day to day playing, handling, taking in and out of the case, etc. causes micro-scratches, and over time makes the horn look worn and not nearly as new looking. Liquid Diabrass protects the finish from the abrasion from everyday playing and handling, and puts an extra hard protective coating on the finish which makes cleaning fast and easy!

The Liquid DiaBrass Solution:

Liquid DiaBrass’s nano properties are scientifically formulated to fill in the microscopic peaks and valleys on new or used horns, and leaves a micron thin layer of hard protection. Adding layers will give more protection, so two, three, or more layers is fine and will not affect the sound of the horn, but will add to the beauty and give better protection over time. Liquid DiaBrass is a very good, non abrasive silver polish, as well!

Directions for Use:

Rinse the horn under running water and let dry, or wipe with a damp cloth.


When the horn is dry, spray the Liquid DiaBrass on one section at a time, and for better results, use your finger to move the Liquid DiaBrass product around to make sure the entire section is coated.


Let the product stay for 30 seconds to a minute, and, using one of the two microfiber cloths, buff the Liquid DiaBrass, using modest pressure.


Then, using the second microfiber cloth, buff the section until it is very shiny and slick. Move to the next section and repeat until the horn is done. Note: ONLY use microfiber clothes.


You may layer several coats. Keep a third microfiber cloth in your case to wipe the horn with after practicing or performing, and you will find fingerprints and smudges come off very easily.


Liquid DiaBrass may be used as often as needed. Used often, your beautiful horn will stay beautiful for years to come!


Nano Polymer Creme

For Brasswinds


DiaBrass is a nano polymer coating, which, when properly applied and allowed to “cure”, will protect your valuable horn for months at a time. Reapply as often as you wish.


Make sure your horn is rinsed and dried. Dab a microfiber towel into the jar, and spread the DiaBrass on the brasswind body one area at a time. Use a moderate amount of pressure. Let stay until it dries, and then buff off. No powder will come off! Move on to a new area until the entire horn is done. Repeat if desired. Once horn is buffed, lay it aside for several hours or overnight in order for the coating to harden. DiaBrass is a hard, beautiful finish, especially formulated for brasswinds. NOT a silver polish.
