Perfect for regular maintenance

I use this every few weeks on my cornet and it keeps everything clean and running smoothly. No harsh chemicals, no damage to the finish, and it gives peace of mind knowing my instrument is properly sanitised. Highly recommend.

Proper game changer for my trumpet

m a college student and play in a brass band, and this stuff is honestly a lifesaver. Didn’t realise how grim my trumpet was until I gave it a soak Now it feels loads freer to play and sounds way cleaner. Dead easy to use as well. Proper worth it.

Brought my trumpet back to life

honestly didn’t realise how much build-up was inside my trumpet until I used this. After one soak, the airflow felt smoother and the valves were noticeably quicker. It even smells fresh instead of that usual stale odour. Definitely a must-have for any brass player.

Great product, just wish the bottle was bigger

Really impressed with how well this works — my trombone feels much cleaner and the slides move better. Only reason for 4 stars is I went through it quite quickly, so I’d love a larger size option. Otherwise, excellent product.

Better than anything I’ve used before

I’ve tried a few cleaning solutions over the years and this is by far the most effective. It removed residue I didn’t think would come off and left a nice protective feel inside the instrument. Super easy to use and worth every penny.
