Experimental Procedure

Twelve pre-weighed stainless-steel coupons were soiled with synthetic blood using a swab and allowed to air dry for 24 hours before recording dirty weights. Two additional coupons were weighed but not soiled to provide a control. Two cleaners were prepared using the specified dilutions and temperature: Biogone (RTU at 22 C); Biogone (1:1 at 22 C).

Six coupons per cleaner were immersed in a beaker for two minutes. Coupons were rinsed in a DI water bath and dried for 48 hours before recording clean weights.

Results

	0.0052	0.0027	48.08
	0.0019	0.0008	-	Control

Conclusion

Both dilutions of Biogone were not effective. The RTU dilution was about 25% more effective than the 1:1 dilution. The same ranking was observed using visual analysis.
