Introductory Special

Buy 6 Sodium Hydroxides or 6 Potassium Hydroxides and 1 is free. Sorry, no mix and match - all six, including your free container, must be the same type of hydroxide.


Dear Valued Customer,

Effective May 13th, 2021 there is a voluntary recall of the 32oz bottles of Sodium Hydroxide and Potassium Hydroxide in cooperation with the U.S. Consumer Product Safety Commission Recall. The products lack a child resistant cap, as required under the Poison Prevention Packaging Act (PPPA), posing a risk of chemical burns and irritation to the skin and eyes. In addition, the products are missing necessary information on cautionary labels.   

The recall is on all 32oz bottles purchased since May 2019.  The remedy will be to offer, free of cost, new child resistant packaging with updated labeling for each full or partial full bottle still in customers possession (photo required).  

See the RECALL INFORMATION box in the MAIN MENU box to the left <<<  for PC or MENU at the top ^^^ on your mobile phone for information on how to initiate your recall.  

TheLyeGuy apologizes for any inconvenience.
