I had the same problem when I mixed the whole bottle with a gallon of distilled water. Ended up dumping it.
When I ordered a Loricraft RCM, they included a bottle of L'Art du Son, a 100ml squeeze bottle, a small measuring beaker and instructions for making up small batches of solutions so you won't have to waste the product. Dilution is approx. 2ml of LDS to 100ml distilled/ultra pure water.
Thumbs up to Smart Devices and Loricraft for top-notch service.
