Horse trailer Cleaner

It's amazing what this product can do for an old fully aluminum horse trailer.

On the exterior, it washed away 18yrs of oxidation in one application.

In the horse compartment, it took a little more work (3 applications),but the results were great.

Unbelievable results

My Daughter purchased a 10 year old aluminum horse trailer that has never been cleaned or washed. I had read the reviews on the Bio-Kleen Step 1 acid wash and all seemed satisfied. I purchased a Gallon......The results were truly amazing...... it went from a oxidized grimy trailer, to new. I used 3/4 of a gallon on a 28 foot all aluminum enclosed horse trailer... I used a fertilizer sprayer and followed instructions.... work from the bottom up. AMAZING PRODUCT!!!


Used on bleachers

  • effective
I work for a college and we had bleachers that had decades of wear. I used the acid wash on them and not only was it easy to use but it did an amazing job on lifting off all the grime.
