The company site lists denatured alcohol Denatured alcohol - Wikipedia while the SDS just lists ethanol. Here is an example of denatured alcohol - Microsoft Word - 6210GHS (chemtel.net) and this a safe solvent, but this is also denatured alcohol \\TAHOE\APPS\MIRS\REPORTS\MSWRPTM.FRX (mscdirect.com) and this is not safe for the record. But, the detergent is diluted 100:1 so even if 5%, in-use it would only be 0.05% - essentially inconsequential.
Industrial cleaning generally accepts pH 6-8 as 'neutral', and Ecover diluted 100:1 should be right in that zone, the ingredients do not include any pH stabilizing (buffering) products like phosphates and silicates. However, the record is pretty immune to alkaline cleaners up to about pH 12. The problem with the high alkaline cleaners is they can be a bear to rinse and residue will dry to 'rocks'.
