Hi George,
Detergents can be classified in 3 main categories:
Enzymatic, Mild Alkaline & High Alkaline.

You may choose to have just one type or a mix of two. Generally, enzymatic detergents are pH neutral. Of the various types of enzymes that are available, you need to look for Proteases. Proteases have a proteolytic action and they are most effective on Proteins. These detergents work most effectively at a temperature range of 45 deg C to 55 deg C. Contact times of 8-10 minutes are required.
Fats (lipids) can be removed more efficiently using alkaline detergents. These work at temperatures of 55 deg C and above. Detergents with a pH of up to 11.0 are called mild alkaline detergents, while those with higher pH are known as High alkaline detergents. High alkaline detergents can be extremely effective, but are extremely corrosive due to their caustic nature. Mild alkaline detergents are very effective as well and are okay to use on a wide range of materials including anodised aluminium.

Some manufacturers recommend that an enzyme wash precedes the alkaline wash. Others are happy to combine both detergents in the same step. Obviously, the second scenario is more efficient time wise.

When you choose detergents, you want them to process all types & materials, not just lap & metal instruments. Also, metals include, stainless steel, anodised aluminium, titanium etc.

Please note that the above are just some aspects. You may also want to look at many others. The washer-disinfector manufacturer will also have a say in this.

Choosing the right detergent that is tailor made for your situation is very vital. You are on the right path.

I take this opportunity to wish you ‘all the very best’ !

Kind Regards
