Pawel Posted June 23, 2021 Share Posted June 23, 2021 I want to clean my windshield where I have some tree sap/bugs. I saw comments that people use this product successfully on windshield. On the other hand on product label it is mentioned that OPC is for all car surfaces except of glass and there are some warnings about etching the glass. Will it be safe to use 1:5 or 1:10 diluted OPC on windshield and then rinse it traditionally or by washing with ONR? If not, which optimum product is supposed to remove tree sap/bugs from the glass?

Ron@Optimum Posted June 23, 2021 Share Posted June 23, 2021 Power Clean can etch glass when used at full concentration and allowed to dry. When diluted and thoroughly rinsed, it's safe on glass. Other options to remove sap/bugs include MDR, TAR, IPA (rubbing alcohol), and WD40. Quote Link to comment Share on other sites More sharing options...
No Soap Posted June 23, 2021 Share Posted June 23, 2021 Tree sap, T.A.R. 😍 Quote Link to comment Share on other sites More sharing options...

Redgrandam Posted June 23, 2021 Share Posted June 23, 2021 OPC does seem to be safe at 3:1 on glass. At least when I used it the other day it seemed fine, for bugs, not letting it dry of course. Quote Link to comment Share on other sites More sharing options...
Ron@Optimum Posted June 23, 2021 Share Posted June 23, 2021 OPT put the no glass recommendation because it's hard to explain caveats in usage and people misused PC then complained. Better to just eliminate the problem. Quote Link to comment Share on other sites More sharing options...
emperors61 Posted November 22, 2021 Share Posted November 22, 2021 Would diluted 3:1 PC used with an air foamer be safe on glass if allowed to dwell for 2-3 minutes, agitated, and then fully rinsed? Quote Link to comment Share on other sites More sharing options...
Ron@Optimum Posted November 22, 2021 Share Posted November 22, 2021 Yes, as long as it's rinsed thoroughly. Power Clean works well in foamers. Quote Link to comment Share on other sites More sharing options...
emperors61 Posted November 23, 2021 Share Posted November 23, 2021 Okay, great. That should make my decon wash much more straightforward. I've switched to using the air foamer for most things over the water foam cannon since all products cling more, and seem to work much better.
