To identify the best cleaning product for removing mud stains from golf balls.
Dirty golf balls were selected, one for each cleaner to be analyzed. The balls were photographed and dirty weights were taken. Solution’s dilutions were then prepared, and balls were immersed in the cleaner. Observations were taken every ten minutes, until 30 minutes. At the 30-minute mark the balls were then allowed to sit in solution for thirty minutes at a time, between observations.
Further testing resulted in heating the solutions to about 60°C and allowing them to be immersed for about 10 minutes, then 20 minutes, and finally 30 minutes. Observations were made and photographs and final weights were taken.
Additionally, the Envirox Har Water and Soap Scum Remover was retested on a different set of dirty golf balls, in order to confirm the efficiency of the product on the hardest to remove dirt. Using the above mentioned heated and timing conditions.
The initial testing in which the golf balls were immersed at room temperature showed that the Hard Water and Soap Scum Remover performed best. After 90 minutes the golf ball assigned to the Envirox cleaner was 100% clean. Additional testing introduced heating to about 60˚C, which caused the degradation of every golf ball due to the high heat. In 10 minute intervals totaling 20 minutes the golf balls experienced some change but the golf ball cleaned with the Hard Water and Soap Scum Remover was still the cleanest with no significant spots of mud.
Further testing sought to confirm the efficacy of the Envirox cleaner by using some golf balls with hard to remove dirt. Many of the balls were significantly whiter, as much of the surface dirt was removed, but still remained less than perfectly clean. These golf balls were especially selected because of their stuck-on dirt.

Table 2. Golf balls cleaned with just Hard Water/ Soap Scum Remover
|Hard Water and Soap Scum Remover
|Heated 60˚C -
|Ball 1: Peeling visible within 10 minutes. Residue on ball. Cleaner after 10 minutes. Noticeably whiter after 1 hour. Close to completely clean after 90 minutes.
|Ball 2: Some dirt removed after 10 minutes. Not as much residue as other balls. Scratched on dirt persistent. Visibly whiter after 1 hour. Stubborn spots left after 2 hours.
|Ball 3: Some color change toward white within 10 minutes. No residue. Visibly cleaner after 1 hour. Clear change from beginning after 2 hours.
|Ball 4: Some removal at 10 minutes and residue. Almost completely clean at 1 hour. Only stubborn spots remained.
|Ball 5: Some dirt removal and color change toward white within 10 minutes. Significantly clean after 1 hour. Almost clean at 90 minutes. Some stubborn spots left after 2 hours.
Success Rating:Results successful using TACT (time, agitation, concentration, and temperature, as well as rinsing and drying) and/or other cleaning chemistries examined.
After 2 hours of heated immersion the Hard Water and Soap Scum Remover could not get rid of these stubborn spots. It would seem that the cleaner works best on surface dirt, as opposed to stuck-on dirt, but it will result in noticeably whiter golf balls.
