Car Wash Chemistry – Titration Testing: Blendco Rhino Brite Plus

When washing cars with a touchless automatic car wash, testing the strength & concentration of your chemicals is critical for ensuring a consistent, quality clean.

Touch free automatic car washes don’t utilise the added friction from brushes to remove contaminants, so your soaps must be performing at optimal levels for a clean & shiny finish.

The other consideration is that you don’t want to be using too much chemical which is both un-economical to your business & can potentially cause damage to vehicles.

How often should you titrate?

Optimally, we say weekly. Do you want to risk 3 weeks out of every month running at the wrong levels & upset customers?

Titration test kits can be purchased from Prowash.
